The Latest: Don’t panic about the latest immunity news

Dear Reader,

Cases of Covid-19 are surging in the U.S. More than 74,300 new cases were reported on Monday, which gets the country’s daily average over the past week to over 71,000. As the New York Times reports, this is the most in any week-long stretch during the pandemic.

If there’s any silver lining to this, it’s that experts anticipate that the number of people hospitalized with Covid-19 on any given day should be lower today than it was over the summer. Why? The way doctors treat people hospitalized with Covid-19 has improved and that appears to be translating to shorter hospital stays and move lives saved.

Even still, over 20 states are reporting Covid-19 cases at or near record levels. And this will still strain hospital resources. The pandemic is extremely fatiguing (I am OVER it). But now is not the time to get lazy about masks!

P.S. If you need tips for a safe Halloween, here’s some epidemiologist-backed advice. 🎃

  • Case count: There are over 8.7 million confirmed cases in the U.S. and over 44 million confirmed cases worldwide. So far over 226,700 Americans have died from Covid-19.
  • Russia orders a national mask mandate: Effective Wednesday, masks will be mandatory in crowded public spaces, such as public transportation, parking lots and elevators. Read more.

Does Covid-19 immunity wane over time?
A new study released this week in the U.K. suggested that antibodies to Covid-19 wane over time. However, some experts are criticizing the way the findings are being covered and interpreted. As Yasmin Tayag reports for the Blog, it’s hard to quantify the amount of antibodies a person gets after infection during a short study period. A decline in antibody levels after the initial illness does not necessarily mean the body has waning immunity to the virus, and antibodies only represent one part of the body’s immune response. Experts say the findings of the new study are expected. Read more about how to interpret them here.
