New surveillance approach to detect outbreaks early
A method used to detect early cases of community transmission of COVID-19 in Seattle is published in the New England Journal of Medicine. Dr. Helen Chu, assistant professor of medicine at the UW School of Medicine, explains how using "swab-and-send," where a swab kit is sent to a home and then sent back for testing, can be an effective strategy in fighting outbreaks, similar to the COVID-19 pandemic. It was a part of Chu's work with the Seattle Flu Study.
"It will allow us to catch cases early," Dr. Chu says. "It will allow us to develop a system to map where the hot spots might be coming up. It will allow us to take measures more quickly to be able to slow down transmission."
