Coronavirus antibodies fall dramatically in first 3 months after mild cases of COVID-19

In people with mild cases of COVID-19, antibodies against SARS-CoV-2 -- the virus that causes the disease -- drop sharply over the first three months after infection, decreasing by roughly half every 36 days, a new study finds. If sustained at that rate, the antibodies would disappear within about a year.
