The sero survey carried out in five zones in Pune has found 51.5% seroprevalence, with the spread ranging from 36.1% in the lower bound to 65.4% in higher bound. The

This seems like an important point for understanding Manaus. If your blood donor samples consist of people who suspected they probably had COVID and wanted a result, you may overestimate

As I predicted a month ago the number of new COVID cases has decreased in the US. From a high of 70,000 per day to 35,000 per day now. It

With @CDCgov's update to their seroprevalence results across sites in the US, it's possible to see if with increased availability in testing whether we're catching a larger fraction of infections

Chapter 1 of the Economic Survey 2020-21 (https://www.indiabudget.gov.in/economicsurvey/ ): a glowing report on the govt's handling of the COVID crisis, and a case study in what happens when science is abandoned

My piece in The Wire on the third national serosurvey. The headline (~21% prevalence) is probably not a major underestimate. Apparently the antibody test used was less vulnerable to missing

Excellent to see new Canadian seroprevalence estimates from @CANBloodServ https://nationalpost.com/news/only-1-5-per-cent-of-canadians-report-covid-19-antibody-immunity-in-second-pandemic-wave-study I think there are some issues with how th

I’m convinced that seroprevalence studies greatly underestimate the true level of immunity of a given population to COVID. Take Sweden: point is not whether they did the right thing. I

Huge ANTIBODY study in NYC among 40,000 health care professionals. Key #COVID19 findings:13.7% were seropositive. Of 6078 w/ previous PCR testing, 34.8% were PCR positive. Of previous PCR-positives, 6.5% had

By July of 2020, 16.8 million people in the US had #COVID19 -- and didn’t know it. Read our pre-print @medrxivpreprint (1/13)https://www.medrxiv.org/content/10.1101/2021.01.27.21250570v1 We called out for volunteers that never

New findings from Swiss seroprevalence and an good opportunity to learn some more infectious disease epidemiology!A similar prevalence in children aged 6 - 18 y (23%) than the adult population

In the past week, COVID cases have fallen in the majority of countries across the globe (see below for weekly change). But not all countries are locked down.A thread on

Thank you, Toby, for providing us a classic example of how to misinterpret seroprevalence data.The stated 68% positive antibody test appears to be from CityMD, an urgent care facility in

India must be being protected by cross reactive immunity from prior corona viral infections. Let us examine the data:1)>2.7 million diagnosed with COVID. 2) Seroprevalence in hotspots: Mumbai slums 57%Pune

India has 1.3 billion people. 4 times that of the US. What’s going on is just amazing and needs in depth immunologic studies. These are raw numbers! When I adjust
