ATLANTA - The Centres for Disease Control and Prevention quietly modified its coronavirus testing guidelines this week to exclude people who do not have symptoms of Covid-19 - even if they have been recently exposed to the virus.
Restricting testing to only people with obvious symptoms of Covid-19 means"you're not looking for a lot of people who are potential spreaders of disease," she added."I feel like this is going to make things worse." "I think it's bizarre," said Assistant Professor Daniel Larremore, a mathematician and infectious diseases modeller at the University of Colorado Boulder."Any move right now to reduce levels of testing by changing guidelines is a step in the wrong direction."
"Wow, that is a walk-back," Dr Butler-Wu said."We're in the middle of a pandemic, and that's a really big change." Although researchers remain unsure how often asymptomatic people unwittingly transmit the coronavirus, studies have shown that the silently infected can carry the virus in high amounts. The evidence is more clear-cut for pre-symptomatic people, in whom virus levels tend to peak just before illness sets in - a period when these individuals might be mingling with their peers, seeding superspreader events.
The reasons behind the surprise shift in testing recommendations are unclear. In response to an inquiry from The New York Times, a representative for the CDC directed the questions to the US Department of Health and Human Services .
