Characteristics of Household Transmission of COVID-19

Jun 22, 2020COVID Literature Appraisal, Epidemiology

The study delves into COVID-19 household transmission dynamics which can guide home isolation policy in non-severe COVID-19 cases. It suggests minimal risk of COVID-19 transmission among household contacts if early and strict isolation (masking, eating and residence) are followed. Physical distancing is suggested for practice within households especially for high risk group and close contacts like spouses. Indoor household transmission of COVID-19 presents a high risk of infection among contacts due to high number of asymptomatic secondary cases. However, with proper case isolation and testing and follow-up of contacts household COVID-19 transmission can be significantly minimized.
