The change that was published Friday reverses that language, saying directly that if someone has been in close contact with a person with COVID-19 infection "you need a test" and to self-isolate for 14 days, even if the test is negative.
The agency's previous position recommended testing all people who have had close contact with anyone diagnosed with Covid-19.
Even along with no signs, "you need to have an exam", the organization's internet site now reviews, "if you have actually resided in near connect with, like within 6 feets of an individual along with recorded SARS-CoV-2 contamination for at the very least 15 mins". 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, ' the site now reads.
'Viral tests are recommended to diagnose acute infection of both symptomatic and asymptomatic individuals, to guide contact tracing, treatment options, and isolation requirements'.
It also said anyone who has been within six feet of an infected person for 15 minutes should get tested for the virus.
Public health experts have noted testing the contacts of infected people is a core element of efforts to keep outbreaks in check, and a large percentage of those infected with the coronavirus exhibit no COVID-19 symptoms.
"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.
To prevent more disproportionate COVID-19 deaths, the CDC's report concluded that health departments, health providers, and community partners must "mobilize to remove systemic barriers that contribute to health disparities".
The head of the CDC, Robert Redfield, told the NYT in a statement following the article's publication yesterday that the guidelines were coordinated in conjunction with the White House Coronavirus Task Force and "received appropriate attention, consultation and input from task force experts".
There was immediate praise for the changes.
The United States's top public health agency has dropped controversial directives around testing for the novel coronavirus, a move that was welcomed as "good news" in the country's fight against the global pandemic.
