Coronavirus Transmission Information Gap Remains Wide Open

A new viewpoint article published by Science states: 'as we learn more about SARS-CoV-2 transmission, important uncertainties remain. The majority of SARS-CoV-2 infections likely occur within households and residential settings such as nursing homes. This is because most individuals live with other people, and household contacts include many forms of close, high-intensity, and long-duration interaction.'

'The relative risk of transmission in different community settings, such as restaurants and retail stores, is still unclear, as is the impact of mitigation measures in these contexts. It is still unknown how seasonality and heterogeneities in the population distribution and duration of immunity will affect future transmission dynamics.'

'Filling these and other knowledge gaps will clarify how the engines of transmission interact to drive the pandemic—and how best to fight back.'
