Title: Secondary Transmission of Coronavirus Disease from Presymptomatic Persons, China Cord-id: ybb0dno4 Document date: 2020_8_25
ID: ybb0dno4
Snippet: We explored the secondary attack rate in different types of contact with persons presymptomatic for coronavirus disease (COVID-19). Close contacts who lived with or had frequent contact with an index case-patient had a higher risk for COVID-19. Our findings provide population-based evidence for transmission from persons with presymptomatic COVID-19 infections.
