    National numbers, January 9

    The national average case rate for the U.S. is twelve times the CDC’s benchmark for “high transmission” (100 new cases per 100,000). Chart via the January 6 Community Profile Report.

    In the past week (January 1 through 7), the U.S. reported about 4.1 million new cases, according to the CDC*. This amounts to:

    • An average of 586,000 new cases each day
    • 1,251 total new cases for every 100,000 Americans
    • One in 80 Americans testing positive for COVID-19
    • 86% more new cases than last week (December 25-31)

    Last week, America also saw:

    • 115,000 new COVID-19 patients admitted to hospitals (35 for every 100,000 people)
    • 8,700 new COVID-19 deaths (2.7 for every 100,000 people)
    • 95% of new cases are Omicron-caused (as of January 1)
    • An average of one million vaccinations per day (including booster shots; per Bloomberg)

    *Here at the COVID-19 Data Dispatch, we’re back to our regular schedule of national updates based on Friday data, as the CDC has resumed weekly reports following its holiday hiatus.

    Omicron continues to drive record cases across the U.S., as we move from tense holiday gatherings to extremely fractured schools and workplaces. This week, the CDC reported 4.1 million new cases—almost double last week’s number, and about 2.5 times the case peak reported during last winter’s surge.

    Put another way: 4.1 million cases amounts to about one in eighty Americans testing positive for COVID-19 in the past week. And that number doesn’t include the vast majority of rapid, at-home tests that continue to be in high demand across the country.

    At the same time, hospitalizations are increasing rapidly, with over 100,000 current COVID-19 patients now reported by the CDC. We appear to be on track to pass last year’s peak, 124,000 COVID-19 patients in beds nationwide.

    I’ve seen a lot of discussion in recent days about hospitalizations “with” COVID-19 versus hospitalizations “for” COVID-19. As Omicron is less severe and more transmissible than other variants, the argument goes, aren’t a lot of those 100,000 COVID-19 patients people who have mild or asymptomatic cases, but tested positive for COVID-19 upon going to the hospital for a different condition?

    While it’s true that some COVID-19 patients in hospitals are “incidental,” meaning their cases were caught during routine hospital screening, these cases can still have a major impact on the hospital system. Healthcare workers need to separate these patients from non-COVID patients, take extra care with their PPE, and utilize other resources. Plus, a lot of patients that, at first, appear to “incidentally” have COVID-19 may see the disease worsen their chronic conditions, such as diabetes or COPD.

    To better understand the strain on hospitals right now, I recommend reading Ed Yong’s latest feature in The Atlantic—which gets into the “with” versus “for” issue, hospital staffing challenges, and other problems.

    When it comes to hotspots: the Northeast continues to see the highest case rates. New Jersey and New York are leading the pack, both with over 2,400 new cases for every 100,000 residents reported in the last week according to the latest Community Profile Report. (Reminder: the CDC threshold for “high transmission” is 100 new cases per 100,000, so New York and New Jersey are at 24 times the rate of this benchmark.)

    Rhode Island, Puerto Rico, D.C., Delaware, Massachusetts, and Florida also have incredibly high case rates, over 1,800 per 100,000 in the last week. Meanwhile, cases are rising rapidly in a number of other Southern and Western states: Texas, the Carolinas, Utah, Arkansas, California, Oregon, and Mississippi have all reported more than 150% case increases in the past week.

    If you are able to work from home and avoid public spaces as much as possible, now is the time to do so. January is going to be rough.

  • Omicron updates: ‘mild’ cases can still mean a nasty surge

    Omicron updates: ‘mild’ cases can still mean a nasty surge

    Image
    Data from South Africa and the U.K. suggest that Omicron patients are less likely to require intensive hospital care than those infected with previous variants. Chart posted on Twitter by Paul Mainwood.

    It’s now been over a month since Omicron arrived in the U.S., and the variant’s impact is clear: January is about to be nasty. Here are the major updates from this week:

    • Omicron continues to cause the majority of new cases in the U.S., but the CDC revised its estimates down this week. On Monday, the agency updated its variant proportions estimates; according to the new data, Omicron caused 59% of new cases in the U.S. in the week ending December 25. Notably, this was lower than the previous week’s estimate of 73%. As I explained in a Twitter thread, the CDC’s variant proportions data are estimates with very wide confidence intervals, based on sequencing data that are reported with a lag of multiple weeks. And the agency’s slow pace of updates means that its estimates are unlikely to match the actual variant situation in the U.S. anyway. Still, the CDC data do tell us that Omicron is causing the majority of U.S. cases right now, and that it became dominant over Delta in under one month.
    • Outdoor concerts in Puerto Rico were a superspreading event for Omicron. Puerto Rico has been a pandemic success story, with one of the highest vaccination rates in the nation. But the territory is currently reporting record COVID-19 cases thanks to Omicron, with an increase of over 5,000% in the space of two weeks. One reason for the increase: a series of concerts by the Puerto Rican rapper Bad Bunny, which have now been connected to at least 2,000 cases according to Puerto Rico’s Office of Epidemiology. The concerts took place in an outdoor stadium, and audience members had to be vaccinated and wear a mask to attend. The high number of cases connected to this event indicates Omicron’s high transmissibility, even in outdoor settings.
    • South Africa’s Omicron wave continues to decline, and London may be seeing a similar pattern. Omicron cases have now been decreasing in South Africa for more than two weeks, with a 30% decline from December 18 to 25. The country’s leaders recently lifted a curfew from midnight to 4 AM, though public gatherings are still restricted to 1,000 people indoors and 2,000 outdoors. A similar decline may be starting in London, another major Omicron hotspot—though holiday reporting delays and high testing demand make it hard to say for sure.

    • Continued evidence that Omicron cases are more likely to be mild. Data out of South Africa continue to show that patients infected with Omicron have a lower risk of severe symptoms than those infected in past waves. One study, published this week in JAMA, finds that the country’s fourth wave has impacted younger patients with “fewer comorbidities, fewer hospitalizations and respiratory diagnoses, and a decrease in severity and mortality.” As I’ve written before, this is likely thanks to South Africa’s high prevalence of immunity from past infections. But a growing number of lab studies are also showing that Omicron may have inherent biological qualities that make it more mild, including a reduced capacity to infect lung cells compared to past variants.
    • It is worth noting, however, that mild, in the clinical sense, means that your case does not require hospitalization. A patient could have a high fever, become bed-bound for days, and even face Long COVID symptoms while still fitting the “mild disease” classification, as Nsikan Akpan discusses in this Gothamist article about his own experience with Omicron. Reminder: we still have next-to-no data on how Omicron may impact the likelihood of Long COVID.
    • Studies continue to indicate that vaccines protect against severe disease from Omicron, though protection against infection is less robust. A new preprint posted this week finds that “most of your T cell responses from vaccination or previous infection still recognize Omicron,” explained study author Wendy Burgers in a Twitter thread. T cells are a type of immune system cell that participates in long-term response; their recognition of Omicron means that vaccinated people are still well-protected against severe disease. At the same time, a new study set to be published in Nature found that vaccinated people who’d received two doses had limited protection against infection, while people with three doses or multiple doses and a prior infection were better protected.
    • Antibodies made during an Omicron infection could provide protection against Delta. In Omicron hotspots, people who recently caught Delta have been readily infected by the new variant. But an Omicron infection may lead to anti-Delta antibodies in your immune system, according to a new preprint from South African scientists who tested blood samples from Omicron patients in the lab. “The researchers found, unsurprisingly, that the patients’ blood contained a high level of antibodies potent against Omicron,” explained Carl Zimmer in the New York Times. “But those antibodies proved effective against Delta, too.” If other studies back up this finding, it could mean that regions with Omicron waves will be protected from Delta resurgence.
    • Pediatric hospitalizations are rising as Omicron spreads, but the variant is not necessarily inherently worse for children. In New York City, one of America’s Omicron hotspots, pediatric hospitalizations increased four-fold from the beginning of December through last week, according to the New York State health department. State leaders are encouraging parents to get their kids vaccinated, as less than one-third of children in the five to 11 age group had received at least one dose as of December 24. As the New York Times points out, low vaccination rates for young kids, combined with the sheer number of cases caused by Omicron, are likely to blame for this increase—rather than some inherent quality of Omicron making it more severe for children.
    • The Omicron surge will be bad in the U.S., but it may boost nation-wide immunity for a few months afterwards. I highly recommend reading through this story by STAT’s Megan Molteni, which walks through several potential scenarios for the Omicron winter surge in the U.S. Some highlights: while South Africa’s short wave is promising, it might not translate to the U.S.; the country will be “in a viral blizzard nationwide” for the next few weeks; massive numbers of Americans will be infected (though their cases may be mild and go unreported); the whole world may be in a similar situation; and those huge case numbers could translate to a lot of immunity in the future. “The thing Omicron will do, because it’s going to infect 40% of the entire world in the next two months, is it will raise population-wide immunity for a while,” Chris Murray, director of IHME, told STAT.

    While COVID-19 case numbers in many parts of the country have shot past last winter’s records, hospitalizations and deaths have remained relatively low. Chart via the New York Times, shared on Twitter by Benjamin Ryan.

    In the past week (December 24 through 30), the U.S. reported about 2.2 million new cases, according to the CDC.* This amounts to:

    • An average of 316,000 new cases each day
    • 674 total new cases for every 100,000 Americans
    • 79% more new cases than last week (December 17-23)

    Last week, America also saw:

    • 71,000 new COVID-19 patients admitted to hospitals (22 for every 100,000 people)
    • 7,700 new COVID-19 deaths (2.4 for every 100,000 people)
    • 59% of new cases are Omicron-caused (as of December 25)
    • An average of 1.3 million vaccinations per day (including booster shots; per Bloomberg)

    *This week’s update, like last week’s, is based on Thursday data (as of December 30) because the CDC has once again taken Friday through Sunday off.

    It’s difficult to interpret COVID-19 data in the wake of any major holiday, as public health officials and testing sites alike take well-deserved time off. The weeks after Christmas are particularly tricky: the numbers are just starting to recover from one holiday when New Year’s hits, causing another round of delays. This year, the CDC took three-day weekends over both Christmas and New Year’s.

    All of that said, we have enough data to say that cases are rising incredibly fast across the U.S. The country reported over 300,000 new cases a day this week—the highest seven-day average of the entire pandemic so far. Over 500,000 new cases were reported on Friday alone.

    New York City continues to be a major Omicron hotspot. Last week, I wrote that one in every 100 New Yorkers had tested positive within a seven-day period, according to NYC data; this week, that number is one in 50. NYC’s positivity rate is over 25%, indicating that one in every four PCR tests conducted in the city is returning a positive result—but also indicating that the city is not testing enough to actually identify all cases. City data don’t include rapid at-home tests, contributing to the data gap here.

    NYC’s case rate seems to be slowing down, suggesting that the city may soon follow South Africa in seeing an intense, yet short Omicron surge. But “growth is still growth,” as analyst Conor Kelly points out:

    Meanwhile, plenty of other places in the U.S. are facing rapid growth from Omicron. In Florida, cases increased by almost 1,000% in the last two weeks of December—bringing the state from the lowest per-capita case rate in the country to the fourth-highest. Several other Southern states have also seen cases more than double in the last week: Georgia, Alabama, Louisiana, California, Mississippi, Washington, and Maryland, among others.

    There is some good news in this surge, though: while COVID-19 cases surge to record highs, hospitalizations remain much lower than they were at this point last year. The CDC currently reports about 67,000 COVID-19 patients in hospitals nationwide, compared to a peak of over 120,000 in January 2021. Omicron hotspots like NYC and DC are similarly reporting hospitalization numbers that, while rising sharply, are not following cases as closely as they did last year. 

    COVID-19 experts call this phenomenon “decoupling”: thanks to vaccinations, treatments, and (possibly) some inherent biological qualities of Omicron, hospitalization increases no longer directly follow case increases. Still, a smaller percentage of cases requiring hospitalization can still mean a lot of hospitalizations, when case numbers are as high as they are right now. And hospitals, already facing dire staffing shortages, were in crisis mode before Omicron hit.

    The seven-day average for new COVID-19 cases in the U.S. on December 23 has passed the peak of the Delta surge. Chart via the CDC.

    In the past week (December 17 through 23), the U.S. reported about 1.2 million new cases, according to the CDC.* This amounts to:

    • An average of 176,000 new cases each day
    • 376 total new cases for every 100,000 Americans
    • 42% more new cases than last week (December 10-16)

    Last week, America also saw:

    • 55,000 new COVID-19 patients admitted to hospitals (17 for every 100,000 people)
    • 8,500 new COVID-19 deaths (2.6 for every 100,000 people)
    • 73% of new cases are Omicron-caused (as of December 18)
    • An average of 1.4 million vaccinations per day (including booster shots; per Bloomberg)

    *This week’s update is based on data as of Thursday, December 23; I typically utilize the CDC’s Friday updates, but the agency is not updating any data from Friday through Sunday this week due to the Christmas holiday.

    Last week, the Omicron surge had clearly arrived; this week, it’s picking up steam. Nationwide, the U.S. reported well over one million new cases this week—more than a 40% increase from last week. 244,000 cases were reported on Thursday alone, and the daily new case average is now higher than at any point during the Delta surge.

    Hospitalization and death numbers have yet to increase so sharply: the number of new COVID-19 patients admitted to hospitals this week is up less than 1%, and the number of new COVID-19 deaths is up by about 4%.

    But when Omicron reaches those Americans who are more vulnerable to COVID-19, they’ll arrive at hospitals already overwhelmed from Delta, the flu, and nearly two years of pandemic burnout. At the same time, Omicron’s incredible capacity to spread will likely cause staffing shortages for many hospitals, as workers get breakthrough cases. On Thursday, the CDC announced that healthcare workers who get sick may shorten their quarantines if their facilities are facing shortages.

    New York City continues to be a major Omicron hotspot: according to city data, one in every 100 New Yorkers has tested positive for COVID-19 in the last week. In Manhattan, the number is one in 60. And these numbers don’t include people who tested positive on rapid at-home tests and weren’t able to confirm it with PCR. The city’s test positivity rate is over 10%, indicating that a lot of cases are going unreported in official data.

    Washington, D.C. has also emerged as a Omicron hotspot this week, with an average of over 1,000 new cases reported daily in the week ending December 22. That’s more than three times higher than the city’s case record at any other point during the pandemic. Meanwhile, several states have seen their case rates more than double in the past week, according to the latest Community Profile Report: Hawaii, Florida, Louisiana, Georgia, and Maryland.

    As Omicron sweeps across the country—aided by holiday travel and gatherings—we are about to face the reporting delays that come with every holiday. Public health workers from local agencies to the CDC are taking time off, while testing sites close for Christmas and millions of rapid tests go unreported.

    Erin Kissane, co-founder of the COVID Tracking Project, wrote about holiday data issues in The Atlantic this week. Her piece concludes:

    In this information vacuum, some of us will tend toward caution and others toward risk. By the time Americans find out the results of our collective actions, the country will have weeks of new cases—an unknown proportion of which will turn into hospitalizations and deaths—baked in. In the meantime, the CDC’s COVID Data Tracker Weekly Review has wished us all a safe and happy holiday and gone on break until January 7, 2022.

    All major COVID-19 metrics shot up in the U.S. this week. Chart from the December 9 HHS Community Profile Report.

    In the past week (December 4 through 10), the U.S. reported about 830,000 new cases, according to the CDC. This amounts to:

    • An average of 119,000 new cases each day
    • 253 total new cases for every 100,000 Americans
    • 37% more new cases than last week (November 27-December 3)

    Last week, America also saw:

    • 52,000 new COVID-19 patients admitted to hospitals (16 for every 100,000 people)
    • 7,600 new COVID-19 deaths (2.3 for every 100,000 people)
    • 99.9% of new cases are Delta-caused (as of December 4)
    • An average of 2.3 million vaccinations per day (including booster shots; per Bloomberg)

    Remember how, last week, I said that the dip in the CDC’s case counts was a vestige of Thanksgiving data delays—and we’d see more cases in the next week? Well, we’re seeing those cases now. Cases have increased by 37% from last week to this week, and they’ve increased by 55% in the last month.

    Hospitalizations are also going up: the number of new COVID-19 patients admitted to hospitals each day has risen 16%, to over 7,000. About 56,000 people are currently hospitalized with COVID-19 in the U.S., as of Thursday. And, tragically, death counts are rising as well: once again, over 1,000 Americans are dying from COVID-19 every day.

    Current hotspots include states in the Northeast and Midwest. New Hampshire reported the most cases per capita last week, at 659 new cases for every 100,000 people, per the latest Community Profile Report. Michigan, Minnesota, Rhode Island, and New Mexico also all reported over 500 new cases for every 100,000 people.

    In many parts of the country, COVID-19 patients have once again pushed hospitals to their breaking points, as the pandemic intersects with staff shortages and burnout as well as flu and other conditions. “We’re at capacity on a daily basis,” the president of a hospital system in Detroit told a local reporter.

    Despite growing Omicron concerns (more on that later), the Delta variant is clearly driving this surge. According to the CDC’s estimates, the Delta variant has caused more than 99% of cases in the week ending December 4, while Omicron has yet to cause even 0.1%. If Omicron is able to outcompete Delta in the U.S., the situation could become even more dire.

    It’s now been two years since a COVID-19 patient first sought medical attention, at a hospital in Wuhan, China. Though most Americans didn’t become aware of the pandemic until March 2020, the coronavirus was already spreading in December 2019—meaning that now, in December 2021, we’re entering Year Three of this global crisis. I hope this can be the year that we get vaccines to every country in the world, and truly get the virus under control.

    Though Omicron is making headlines, Delta is still causing 100% of COVID-19 cases in the U.S. Chart via the CDC, screenshot taken on December 5.

    In the past week (November 27 through December 3), the U.S. reported about 600,000 new cases, according to the CDC. This amounts to:

    • An average of 86,000 new cases each day
    • 184 total new cases for every 100,000 Americans
    • 8% fewer new cases than last week (November 20-26)

    Last week, America also saw:

    • 45,000 new COVID-19 patients admitted to hospitals (14 for every 100,000 people)
    • 6,000 new COVID-19 deaths (1.8 for every 100,000 people)
    • 100% of new cases are Delta-caused (as of November 27)
    • An average of one million vaccinations per day (including booster shots; per Bloomberg)

    Don’t be fooled by the apparent case decline in the CDC’s numbers: the U.S. is still in the midst of a new surge. The agency reported fewer cases last week due to Thanksgiving holiday delays, but we can expect cases to shoot up next week as delayed cases are added to the data.

    I use the CDC for these updates because I find the national agency’s data reliable and easy to access, but the CDC does tend to be more heavily impacted by reporting delays than other sources which compile numbers from U.S. states or counties. For example, the New York Times is reporting a daily new case average of 108,000 as of December 4, while BNO Newsroom has reported over 100,000 new cases for five days in a row.

    Meanwhile, hospitalizations are ticking up: with 45,000 new COVID-19 patients admitted to U.S. hospitals last week and almost 50,000 people currently hospitalized, as of December 2. Hospitalizations are one COVID-19 metric that tends to be less impacted by holidays, as the hospitals collecting these data don’t take days off.

    Northern states continue to lead the country in new cases per capita. According to the latest Community Profile Report, top hotspots are New Hampshire, Michigan, Minnesota, North Dakota, and Wisconsin. New Hampshire reported over 500 new cases for every 100,000 people in the last week, and is continually setting new COVID-19 records.

    Michigan is seeing more cases now than it has in any previous surge, and the state’s hospital systems—like many others—are facing dire staff shortages, along with increased numbers of flu patients. The state has almost 900 fewer staffed hospital beds now than in November 2020, according to ABC News.

    While the Omicron variant has now been identified in more than ten U.S. states (more on that below), the Delta variant is still driving this current surge. According to the CDC’s latest variant data, 100% of new cases in the country are caused by Delta. In the coming weeks, we’ll see how much Omicron is able to compete.

  • Cases are rising on Thanksgiving again, but we’re better protected this year

    Cases are rising on Thanksgiving again, but we’re better protected this year

    Before the Omicron news hit on Thursday, I was planning to write a big post about how the state of the pandemic in the U.S. at Thanksgiving this year compares to the state of the pandemic at Thanksgiving last year. But, well, Omicron happened—so here’s a small post about Thanksgiving, instead.

    Remember: last year, Thanksgiving was a turning point in the winter 2020 surge. While cases had already been going up prior to the holiday, the convergence of travel, indoor gatherings, and cold weather helped the coronavirus spread further. Christmas did the same thing, one month later.

    This year, we saw cases increase once again in the weeks prior to Thanksgiving. But we’re better protected this time, thanks to vaccines and better knowledge of the virus.

    Let’s look at the national metrics:

    • On November 23, 2021 (two days before Thanksgiving), the seven-day average of new COVID-19 cases was about 94,000 new cases a day. That’s about 45% lower than last year’s number, 170,000 new cases a day (on November 26, 2020, Thanksgiving itself).
    • On November 23, 2021, the seven-day average of new COVID-19 deaths was about 1,000 new deaths a day. That’s about 45% lower than last year’s number, 1,800 new deaths a day.
    • On November 25, 2021 (Thanksgiving day), 43,000 people were hospitalized with COVID-19 in facilities across the U.S. That’s just under half as many as the number of patients hospitalized last year, 84,000 people.
    • As of November 24, 2021, 196 million Americans are fully vaccinated against COVID-19—and an additional 35 million have received at least one dose, while more than 37 million have received booster shots.

    Clearly, while the trajectory of cases (and other metrics) may be the same as they were last year, the numbers are way lower. But the national metrics obscure local patterns. In some parts of the country, particularly some northern states, case numbers are actually higher at Thanksgiving this year than they were last year. 

    You can see how your county is faring on this map, which I put together for a DailyMail.com story on this topic. Use the drop-down menu at the top to click between Thanksgiving 2020 and Thanksgiving 2021.

    For that DailyMail.com story, I asked several COVID-19 experts for their thoughts on this winter’s oncoming surge, as well as their advice for staying safe while gathering for the holidays. Key pieces of advice included:

    • Get vaccinated, including a booster shot if you’re eligible.
    • Get tested prior to travel or large gatherings.
    • Use high-quality masks (especially N95s and KN95s) while traveling.
    • Be aware of case rates at both your point of origin and your destination.
    • If you’re gathering indoors with others, make sure everyone is on the same page about safety.

    New York City is now seeing about 14 new cases for every 100,000 people each day. Chart via THE CITY’s COVID-19 dashboard.

    In the past week (November 13 through 19), the U.S. reported about 620,000 new cases, according to the CDC. This amounts to:

    • An average of 88,000 new cases each day
    • 189 total new cases for every 100,000 Americans
    • 16% more new cases than last week (November 6-12)

    Last week, America also saw:

    • 38,000 new COVID-19 patients admitted to hospitals (12 for every 100,000 people)
    • 7,200 new COVID-19 deaths (2.2 for every 100,000 people)
    • 100% of new cases are Delta-caused (as of November 13)
    • An average of 1.3 million vaccinations per day (including booster shots; per Bloomberg)

    Last week, I wrote that the U.S. was at the start of a winter surge; this week, the surge is beginning to take off. Nationwide, cases are up 16% from last week to this week, and up 24% from two weeks ago. It’s not as sharp of an increase as what we saw during the first Delta surge in the summer, but it’s still concerning. New hospitalizations are also rising, up about 5% from last week.

    Michigan and Minnesota are now the country’s top hotspots, with 589 and 524 new cases for every 100,000 people in the past week, respectively, per the latest Community Profile Report. Other hotspots include more northern states: New Hampshire, North Dakota, Wisconsin, Vermont. After being a success story for most of the pandemic, Vermont is now seeing its highest case numbers yet.

    Meanwhile, in Europe, the ongoing surge has prompted increasingly strict COVID-19 safety measures. The government of Austria, which is also seeing record-high case numbers, announced on Friday that COVID-19 vaccination is now mandatory for the entire adult population. This follows a lockdown for unvaccinated Austrians only.

    Nearly 80% of Austrian adults are vaccinated, according to the New York Times; the U.S. is in a similar position. But here, all the attention is on booster shots—more than 33 million Americans have now received boosters—and on shots for kids in the recently eligible 5 to 11 age group. About 10% of kids in that age group have now received their first doses, which may seem less impressive when one considers that the U.S. had enough doses for the entire eligible population ready to go when the FDA and CDC approved the shots.

    In NYC, where I live, the case rate is now up at about 14 new cases for every 100,000 people, every day. That adds up to almost 100 new cases for every 100,000 people in the last week, meeting the CDC’s threshold for high transmission. About three in every four residents are vaccinated.

    To combat this increase, city leaders announced on Monday that all adults were eligible for a booster shot—a few days before the FDA and CDC made the same decision for all adults in the U.S. (More on that eligibility later in this issue.) But no efforts have been made to cut down on indoor dining, curb the crowds in Times Square, or actually enforce mask-wearing on the subway. In this new surge, it truly feels like everyone is out here fending for themselves.

  • Thinking about COVID-19 risk as winter approaches

    Thinking about COVID-19 risk as winter approaches

    I recently received a question from a COVID-19 Data Dispatch reader that followed a similar theme to many questions that readers, friends, and family members have asked me in the past few months. The question essentially outlined an event in the reader’s personal life that they’d been invited to attend, and asked for my advice: should they go? How risky was this event?

    I have a hard time answering these types of questions directly, because I am no medical expert—I’m far from qualified to give direct advice. Instead, I like to outline my own attitudes towards risk at the pandemic’s current moment, and try to explain what I might do in that situation.

    Right now, this type of decision-making feels harder than ever before. The majority of Americans are fully vaccinated, and we know how well the vaccines work. A growing number of Americans are getting booster shots, which we know are highly protective for seniors (and at least seem to reduce infection risk for others). So many of us are tired of the pandemic, and want to have a normal holiday season this year.

    But at the same time, I feel an impetus to stay cautious—to protect the people around me as much as I can—as COVID-19 cases start to rise again in New York City, where I live, and in many other places around the country. 

    It’s also important to note here that everyone has a different risk comfort zone right now, partially as a product of a dearth of local and federal safety regulations at this point in the pandemic. If you’re fully vaccinated, and you’re comfortable hanging out inside with a large group of fully vaccinated people, there is evidence to suggest that is a largely safe situation for you. But if you’re not comfortable at such an event, there is also evidence to suggest that you may be able to pick up the coronavirus (even from a fully vaccinated crowd) and bring it back to someone who is more vulnerable than you are. Every choice comes with a calculation—what risk are you willing to bring to yourself and to those around you? 

    With all of that in mind, there are a few things I consider when I try to decide how “risky” an event might be. First of all, I still consider outdoor events to be very safe; the benefits of open air, wind, and sun far outweigh Delta’s high capacity for transmission. Then, for indoor events, I think about a few different layers of safety measures:

    • Will everyone be fully vaccinated?
    • Will negative COVID-19 tests be required before the event?
    • Will masks be required?
    • Will windows be open, or will ventilation in the space otherwise be high-quality?
    • What are the COVID-19 case numbers in the surrounding county; are they above or below the CDC’s “substantial transmission” threshold (50 total new cases for every 100,000 people in the past week)?

    When at least three of these five conditions are met, I personally would consider an event safe for attendance. When fewer than three conditions are met, I tend to add additional layers of protection for myself and others in my immediate community by wearing a high-quality mask and getting tested before and after. (I might use an at-home rapid test or a PCR test, depending on how much security I want in that test result.

    Finally, if you’d rather listen to the insights of some high-profile COVID-19 experts than to me, I’ve got a source for you: STAT News recently surveyed 28 infectious disease experts on which activities they would feel comfortable doing right now. The responses to STAT’s survey reveal a diversity of risk comfort levels, even among people who are incredibly well-informed about the pandemic.

    The vast majority of experts said they would travel by air, train, or bus for Thanksgiving (mostly with a mask on), and the majority said they would not attend an indoor concert or event without mandatory masks. Other than that, all the questions are fairly split. The article (which I recommend reading in full!) includes a number of insights from those experts explaining their survey responses.

    Many Northern states are seeing cases increase right now as Southern states have lower transmission levels. Charts from the November 10 Community Profile Report.

    In the past week (November 6 through 12), the U.S. reported about 510,000 new cases, according to the CDC. This amounts to:

    • An average of 73,000 new cases each day
    • 156 total new cases for every 100,000 Americans
    • 3% more new cases than last week (October 30-November 5)

    Last week, America also saw:

    • 36,000 new COVID-19 patients admitted to hospitals (11 for every 100,000 people)
    • 7,000 new COVID-19 deaths (2.1 for every 100,000 people)
    • 100% of new cases are Delta-caused (as of November 6)
    • An average of 1.4 million vaccinations per day (including booster shots; per Bloomberg)

    It may be happening slowly, but the U.S. is clearly at the start of a winter COVID-19 surge. The number of newly reported cases rose this week for the first time since early September, while the number of COVID-19 patients in hospitals has plateaued.

    Delta is still causing practically 100% of COVID-19 cases in the country, so a new variant is probably not to blame for this potential surge. Instead, it’s a consequence of the cold weather, combined with less-stringent safety behaviors among many Americans as we approach the holiday season. One epidemiologist told NBC that a surge may be “inevitable” at this time of year.

    In line with COVID-19’s cold-weather advantage, many Northern states are seeing cases increase right now as Southern states—which were hit harder by the summer Delta surge—have lower transmission levels. Alaska, North Dakota, New Mexico, Montana, and Wyoming had the highest case rates last week, per the latest Community Profile Report.

    Cases are also rapidly increasing in Maine, Vermont, Minnesota, Michigan, Colorado, and other chillier states. At Vermont’s St. Michael’s College, Halloween parties were a major source of new COVID-19 cases—even though 98% of people on campus are vaccinated, according to local outlet WCAX3.

    Still, it’s important to point out here that the U.S. is in a far better spot now than we were at this time last year. As Dr. Ashish Jha pointed out on Twitter recently, we have winter coming and the vast majority of schools in the country are open, but cases are flat rather than rising sharply as they did last November.

    Of course, we have vaccines to thank for this improved position. More than two-thirds of the U.S. population has received at least one vaccine dose; as of this week, that number includes over one million children under age 12, according to the CDC. Vaccinating more children and other people who are currently unvaccinated, booster shots for seniors, and continued use of masks and testing can help keep case numbers (relatively) low as we head into the coldest months.
