- Mass and frequent speedy testing for COVID-19 might make a big dent within the pandemic inside six weeks, a brand new examine claims.
- “Our huge image discovering is that, in relation to public well being, it is higher to have a much less delicate take a look at with outcomes immediately than a extra delicate take a look at with outcomes tomorrow,” stated Daniel Larremore, a pc science professor at Colorado College Boulder and lead creator of the examine.
- Testing 75% of a metropolis’s inhabitants each three days would scale back infections by 88%, “enough to drive the epidemic towards extinction inside six weeks.”

Mass rapid-testing for COVID-19 — particularly of these individuals exhibiting no indicators of an infection — might convey an finish to the pandemic inside six weeks, claims a brand new examine by researchers on the Harvard TH Chan College of Public Well being and the College of Colorado Boulder.
Printed November 20 within the peer-reviewed journal Science Advances, the study means that speedy assessments, though much less dependable, might enable public well being authorities to depend on extra focused interventions, quite than economy-wide lockdowns, if deployed on an enormous scale.
Speedy assessments are low value and may return leads to a matter of minutes, quite than the times related to the lab selection. If half the US inhabitants had been examined weekly, with those that take a look at optimistic isolating from the remainder, the impression can be huge, researchers stated.
“Our huge image discovering is that, in relation to public well being, it is higher to have a much less delicate take a look at with outcomes immediately than a extra delicate take a look at with outcomes tomorrow,” Daniel Larremore, a pc science professor at CU Boulder and lead creator of the examine, stated Friday. “Relatively than telling everybody to remain dwelling so you may ensure that one one who is sick does not unfold it, we might give solely the contagious individuals stay-at-home orders so everybody else can go about their lives.”
In keeping with the examine, based mostly on mathematical modeling, rapid-testing three-quarters of a metropolis’s inhabitants each three days slashed the variety of these in the end contaminated by 88%, “enough to drive the epidemic towards extinction inside six weeks.”
“These speedy assessments are contagiousness assessments,” Michael Mina, a professor of epidemiology at Harvard and coauthor of the examine, stated in a information launch. “They’re extraordinarily efficient in detecting COVID-19 when individuals are contagious.”
Rising the supply of “low cost, speedy assessments” is without doubt one of the key methods into account by President-elect Joe Biden, Politico reported Friday.
