*The determination can be made at the time the patient is confirmed to be positive (i.e., at baseline, an interim visit, or day 14)


Notes for field investigators:

  • Primary case/s

    • Primary case is the confirmed COVID-19 case with the earliest symptom onset in the household. Oftentimes, this will be the index patient.

    • If there are multiple household cases who have the earliest symptom onset (within a day; or, not within a day but they have a known common exposure), we will consider them as co-primary cases who introduced the virus into the household. Please check them as primary cases in the table.

  • Secondary cases

    • Ideally, we’d like to identify secondary cases as household members who are subsequently infected by the primary case/s.

    • However, in practice, we may not be able to differentiate secondary vs. tertiary (or further generations of) transmission, or infections due to exposure outside of the household

    • Thus, for now, we plan to consider all subsequent infections in the household as secondary cases, and estimate the overall risk of infection (i.e., % household members subsequently infected) as a proxy for household secondary attack rate

      • This approach assumes that all subsequent infections in the household are due to exposures to the primary case/s

      • As the above assumption may be violated, please mark household cases with suspected/known infection due to outside sources as; as a sensitivity analysis, we will consider excluding them when estimating the secondary attack rate
