Since BA.2.86 emerged a couple of weeks ago, scientists around the world have been racing to evaluate this variant. Several teams posted data in the last week, and the news is promising: while BA.2.86 does have an advantage over past variants, the lab findings suggest that vaccines (including the upcoming boosters) and past infections provide protection against it.
This week, the health department in New York City, where I live, announced that they’d identified new variant BA.2.86 in the city’s wastewater. I covered the news for local outlet Gothamist/WNYC, and the story got me thinking about how important wastewater surveillance has become for tracking variants.
Last week, I introduced you to BA.2.86, a new Omicron variant that’s garnered attention among COVID-19 experts due to its significant mutations. We’ve learned a lot about BA.2.86 since last Sunday, though there are many unanswered questions to be answered as more research is conducted.
Last week, several variant experts that I follow on Twitter started posting about a new SARS-CoV-2 variant, first detected in Israel. They initially called it Omicron BA.X while waiting for more details to emerge about the sequence; it’s now been named BA.2.86.
Marc Johnson, a molecular virologist and wastewater surveillance expert at the University of Missouri, recently went viral on Twitter with a thread discussing his team’s investigation into a cryptic SARS-CoV-2 lineage in Ohio. I was glad to see the project get some attention, because I find Johnson’s research in this area fascinating and valuable for better understanding the links between coronavirus infection and chronic symptoms.
A few months ago, I wrote about how testing sewage from airplanes could be a valuable way to keep tabs on the coronavirus variants circulating around the world. This spring, San Francisco International Airport became the first in the U.S. to actually start doing this tracking; I covered their new initiative for Science News.
COVID-19 spread continues to trend down in the U.S., though our data for tracking this disease is now worse than ever thanks to the end of the federal public health emergency. If newer Omicron variants cause a surge this summer, those increases will be hard to spot.
We’re now less than one week out from May 11, when the federal public health emergency (or PHE) for COVID-19 will end. While this change doesn’t actually signify that COVID-19 is no longer worth worrying about, it marks a major shift in how U.S. governments will respond to the ongoing pandemic, including how the disease is tracked and what public services are available. Here’s all the key info you should know about this, in one place.
GISAID, the global database of virus sequences, has faced a lot of criticism recently from the virologists and bioinformaticians who rely on it—potentially hindering responses to future virus outbreaks.
