The antibody surveillance study “Household transmission of SARS-CoV-2 from unvaccinated asymptomatic and symptomatic household members with confirmed SARS-CoV-2 infection” published in CMAJ Open (Canadian Medical Association Journal) included 695 participants from 180 households in Ottawa between September 2020 and March 2021. The study included households with at least one member having had a confirmed COVID-19 infection, and each participating household enrolled had at least one child within their household. “Our study was conducted when we were dealing with a less transmissible virus and pandemic restrictions were strongly in place, and we still had a 50% transmission rate within households. Flash forward to where we are today with an extremely transmissible variant of COVID-19 and the majority of pandemic restrictions lifted; it’s safe to say transmission rates will be higher even though we have a high vaccination rate amongst those who are eligible,” said Dr. Maala Bhatt
