Rapid testing can wipe out Covid-19 spread within weeks: Study

Hindustan Times  

A new study published by the University of Colorado Boulder and Harvard University researchers claims that frequent and rapid testing could eliminate Covid-19 spread within weeks. The lead author Daniel Larremore, an assistant professor of computer science at CU Boulder said in the report, “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 one with results tomorrow.” Larremore added, “Rather than telling everyone to stay home so you can be sure that one person who is sick doesn’t spread it, we could give only the contagious people stay-at-home orders so everyone else can go about their lives.” As per the reports of Science Daily, the researchers from BioFrontiers Institute and the Harvard T.H. The researchers stated the reason and said, “When the amount of testing was the same, the rapid test always reduced infectiousness better than the slower, more sensitive PCR test,” “That’s because about two-thirds of infected people have no symptoms and as they await their results, they continue to spread the virus,” the authors added. Senior co-author Roy Parker, director of the BioFrontiers Institute and a Howard Hughes Medical Institute investigator said, “This paper is one of the first to show we should worry less about test sensitivity and, when it comes to public health, prioritize frequency and turnaround.” “In one scenario, in which 4 per cent of individuals in a city were already infected, rapid testing three out of four people every three days reduced the number ultimately infected by 88 per cent and was sufficient to drive the epidemic toward extinction within six weeks,” Parker added.
