Asymptomatic patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection must be quickly
identified and isolated to prevent the spread of the virus. The number of asymptomatic healthy people is completely
unknown because they remain untested. Detection of specific SARS-CoV-2 antibodies has been widely accepted as a
diagnostic test, and an immunochromatographic test, which is simpler and relatively cheaper than other methods, is
becoming the gold standard for identifying healthy people who had been infected with SARS-CoV-2 in the past. In
this study, 1,528 volunteers who worked at a particular hospital were subjected to an immunochromatographic IgG
test for SARS-CoV-2 to determine the ratio of asymptomatic people. Only 12 volunteers (0.79%) were IgG+, with no
significant background differences in the sex, age, profession, experience.. View More»
