Asymptomatic transmission – The claim healthy people can spread infections
The screening of the 9,865,404 participants without a history of COVID-19 found no newly confirmed COVID-19 cases, and identified 300 asymptomatic positive cases with a detection rate of 0.303. A total of 1174 close contacts of the asymptomatic positive cases were traced, and they all tested negative for the COVID-19. (Wuhan-Study 2020)
