Prevalence of antibodies

 * Coronavirus UK: Half population could be infected, says expert - Daily Mail Online,
 * ''The new model from Oxford University suggests the virus was circulating in the UK by mid-January, around two weeks before the first reported case and a month before the first reported death.
 * ''This means it could have had enough time to have spread widely, with many Britons acquiring immunity. Sunetra Gupta, a professor of theoretical epidemiology who led the study, said testing was needed to assess the theory. ‘We need immediately to begin large-scale serological surveys – antibody testing – to assess what stage of the epidemic we are in now,’ she said.

Knowing the true infection rate would allow one to determine the fatality rate. If infections have been more widespread than estimated then the fatality rate is lower. If they are not more widespread then the fatality rate has not been overestimated. Nassim Taleb argues contra John Ioannidis that uncertainty in data increases the risk of underestimation.

False positives?

 * Chris Martenson If the new Antibody tests are 93.5% accurate (i.e. "sensitivity') then this means if true incidence of Covid in population is 1%, the test will return a false positive 82% of the time.
