B.1.1.7. B.1.351. P1. B.1.671.2. It’s exhausting trying to keep up with emerging SARS-CoV-2 variants with names as inscrutable as these.
But thankfully, we finally have a straightforward naming system: on May 31, the WHO announced a system using letters of the Greek alphabet. B.1.1.7 (first identified in the U.K. is now Alpha, B.1.351 (first identified in South Africa) is now Beta, and so on. You can find the complete list (so far) here. While there are an innumerable amount of SARS-CoV-2 variants, so far the WHO naming system only applies to “variants of concern” and “variants of interest.”
While there have been non-place-related names for these variants for a while, colloquially they have been called things like “the U.K. variant” and “the South African variant” because most people won’t just toss “B.1.1.7” around in conversation. (I tried, and no one knew what I was talking about.) However, this is problematic for a few reasons. First, we don’t know for sure that B.1.1.7. originated in the United Kingdom — that’s just where they found it first. And for other countries, naming a coronavirus variant after them associates a dangerous stigma with that country (like how nicknaming the coronavirus “the China virus” earlier in the pandemic contributed to a rise in anti-Asian hate). According to WHO coronavirus lead Maria Van Kerkhove in an interview with STAT News, a country will be more likely to report a variant if the name of the variant will not be associated with the country name.
The WHO naming system is nice for now, but it’s not clear if it’ll catch on and become the norm or if it’ll just be yet another naming system in a crowded patchwork. It’s also unclear what will happen if we run out of Greek letters, but we certainly hope it doesn’t come to that. (Making this yet another reason to vaccinate the world.)
More variant data
- It’s time to worry about the Delta variantThe Delta variant (also known as B.1.617.2) was first identified in India earlier this spring. It’s now known to spread more easily than any other variant found so far and evade immunity from a prior COVID-19 infection. It’s now spreading rapidly in the U.S.
- New variant names from the WHOWe finally have a straightforward variant naming system: on May 31, the WHO announced a system using letters of the Greek alphabet. B.1.1.7 (first identified in the U.K. is now Alpha, B.1.351 (first identified in South Africa) is now Beta, and so on.
- Why did the CDC change its breakthrough case reporting?Earlier this month, the CDC made a pretty significant change in how it tracks breakthrough cases. Instead of reporting all cases, the agency is only investigating and collecting data on those cases that result in hospitalizations or deaths. Here’s what this decision means, and why I’m calling it a lazy move.
- National numbers, May 30Cases, deaths, and hospitalizations all continue to drop nationwide. The U.S. reported about 3,000 COVID-19 deaths last week, in total—at the peak of the winter surge, we saw more than 3,000 deaths a day.
- Source updates, May 16Two more important CDC data updates for this week: the CDC added more options for its vaccine demographic data and more recent variant data.
