Rapid testing 75% of a city every 3 days could 'drive the epidemic toward extinction' within 6 weeks, a new study claims
- Mass and frequent rapid testing for
COVID-19could make a large dent in the pandemic within six weeks, a new studyclaims.
- "Our big picture finding is that, when it comes to
public health, it's better to have a less sensitive test with results today than a more sensitive test with results tomorrow," said Daniel Larremore, a computer scienceprofessor at Colorado University Boulder and lead author of the study.
- Testing 75% of a city's population every three days would reduce infections by 88%, "sufficient to drive the epidemic toward extinction within six weeks."
Mass rapid-testing for COVID-19 — especially of those people showing no signs of infection — could bring an end to the pandemic within six weeks, claims a new study by researchers at the Harvard TH Chan School of Public Health and the University of Colorado Boulder.
Published November 20 in the peer-reviewed journal Science Advances, the study suggests that rapid tests, although less reliable, could allow public health authorities to rely on more targeted interventions, rather than economy-wide lockdowns, if deployed on a massive scale.Rapid tests are low cost and can return results in a matter of minutes, rather than the days associated with the lab variety. If half the US population were tested weekly, with those who test positive isolating from the rest, the impact would be enormous, researchers said.
According to the study, based on mathematical modeling, rapid-testing three-quarters of a city's population every three days slashed the number of those ultimately infected by 88%, "sufficient to drive the epidemic toward extinction within six weeks.""These rapid tests are contagiousness tests," Michael Mina, a professor of epidemiology at Harvard and coauthor of the study, said in a news release. "They are extremely effective in detecting COVID-19 when people are contagious."
Increasing the availability of "cheap, rapid tests" is one of the key strategies under consideration by President-elect Joe Biden, Politico reported Friday.Have a news tip? Email this reporter: firstname.lastname@example.org
