People who have no symptoms of COVID-19 “do not necessarily need a test,” even if they have been in close contact (within 6 feet) with an individual who has tested positive for the virus for at least 15 minutes, the CDC now recommends.
“A negative test does not mean you will not develop an infection from the close contact or contract an infection at a later time,” the CDC said. “It is important to realize that you can be infected and spread the virus but feel well and have no symptoms.”
The federal agency previously advised that all people who came into close proximity with a COVID-19-positive patient should be tested for the virus, even if they displayed no symptoms.
It also recommends testing vulnerable populations, including residents and staff in nursing homes or long term care facilities, critical infrastructure workers, healthcare workers and first responders, and those individuals (who may be asymptomatic) when prioritized by public health officials.
“And finally, through continuously evaluating the data we know we have strong, proven preventive measures for reducing the spread of COVID-19: wearing a face mask, watching your distance, washing your hands, and avoid large gatherings and crowded indoor spaces,” Giroir added.
“I was under general anesthesia in the operating room and was not part of any discussion or deliberation regarding the new testing recommendations,” Fauci said.
He added that he is concerned the updated guidelines will downplay the threat of asymptomatic COVID-19 spread.
“I am concerned about the interpretation of these recommendations and worried it will give people the incorrect assumption that asymptomatic spread is not of great concern. In fact it is,” Fauci said.
Fauci in June highlighted the challenge posed by the high asymptomatic spread of COVID-19, which some research has put at up to 45 percent.
“We now know the level of virus in an asymptomatic person is about the same as the level of virus in somebody who has symptoms,” Fauci said at the time in remarks to The Washington Post. “So it’s like, oh my goodness, how do you address that?”
