Coronavirus Outbreak: US CDC updates guidelines on testing asymptomatic people

Filmmaker Anurag Kashyap has responded to the #MeToo allegations levelled against him by Bollywood actor Payal Ghosh, saying all the charges are baseless.

The US Centers for Disease Control and Prevention (CDC) has updated its guidelines for testing people who do not show symptoms of the novel coronavirus.

“Due to the significance of asymptomatic and pre-symptomatic transmission, this guidance further reinforces the need to test asymptomatic persons, including close contacts of a person with documented SARS-CoV-2 infection,” Xinhua news agency quoted the CDC as saying on its website on Friday.

“Testing is recommended for all close contacts of persons with SARS-CoV-2 infection. Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested,” it added.

It is a change from the CDC guidance released last month which said testing might not be necessary for people withoutsymptoms.

“Viral tests are recommended to diagnose acute infection of both symptomatic and asymptomatic individuals, to guide contact tracing, treatment options, and isolation requirements,” according to the CDC website.

The guidance notes that even if people do not have symptoms, they still need a test if they have been in close contact — such as within 6 feet — of a person with coronavirus infection for at least 15 minutes.

“In areas where there are a small number of new cases and limited spread, your public health department may request a small number of asymptomatic ‘healthy people’ to be tested,” said the updated guidance.

If there is significant spread of the virus in the community, public health department may request significant numbers of asymptomatic “healthy people” to be tested in order to help stop the spread of the virus, according to the guidance.

On August 24, the CDC changed Covid-19 testing guidelines on its website, no longer recommending testing for most people without symptoms.

The move has sparked controversy as experts warn it may hamper the timely identification of asymptomatic individuals.

According to a report of The New York Times earlier this week, the recommendation published in August was not written by CDC scientists and was posted to the agency’s website despite their serious objections.

The US remains the worst-hit country with the world’s highest number of cases and deaths at 6,722,699 and 198,509, respectively, according to the Johns Hopkins University.
