“…Previous COVID-19 transmission studies have shown that sharing a bedroom with the index individual significantly increases transmission risk, while self-reported mask wearing by contacts or the index individual significantly decreases transmission risk [ 8 , 9 ]. In a PEP study, differences in household demographics, the severity of an index individual’s illness, and their interactions with household members can lead to very different risks of transmission within the household.…”

“…Although studies primarily assessing COVID-19 transmission often enroll both the index individuals and their contacts [ 6 , 7 ], to our knowledge no studies assessing COVID-19 PEP have enrolled index individuals because they do not directly inform the efficacy of prevention interventions. However, the severity of an index individual’s illness and their interaction with household members are important predictors of infection in their household contacts [ 8 , 9 ], and adjusting for prognostic covariates such as these can increase the precision of PEP efficacy estimates [ 10 ].…”
