All 5 household contacts of patient 1 had laboratory evidence of SARS-CoV-2 infection but remained asymptomatic throughout the period of observation (February 11-March 1) (Figure, panel A) . An early report from China on 72,314 COVID-19 cases found that only 1% of SARS-CoV-2 infections were asymptomatic; however, asymptomatic close contacts were not routinely tested in that study (7) . In summary, this single-household study found a high attack rate for asymptomatic SARS-CoV-2 infection among the immediate family members of a symptomatic COVID-19 case-patient. Moreover, our experience indicates that screening symptomatic contacts with a single throat swab test for SARS-CoV-2 might lead to an underestimate of the rate of infection and that asymptomatic persons can repeatedly revert between positive and negative PCR results on throat specimens.	./cache/cord-334945-lxowaacg.txt	./txt/cord-334945-lxowaacg.txt
