After Recovery From the #Coronavirus, Most People Carry Antibodies - The New York Times
La plus grande série, étasunienne, de #sérologie à ce jour chez des personnes ayant développé antérieurement un COVID-19. Tous sauf 3 ont développé des anticorps y compris ceux qui avaient développé des formes légères de #COVID-19 (dont on pensait qu’ils en développaient moins). Le test utilisé a un taux de faux positif de moins de 1%.

Several small studies have given reason to hope that people who have had Covid-19, the illness caused by the coronavirus, would gain some immunity for some period of time. The new study is the largest by far, with results from 1,343 people in and around New York City.
The study also eased a niggling worry that only some people — only those who were severely ill, for example — might make antibodies. In fact, the level of antibodies did not differ by age or sex, and even people who had only mild symptoms produced a healthy amount.
