The Centers for Disease Control and Prevention is warning that as many as 25 percent of people infected with the novel coronavirus (COVID-19) may be asymptomatic, meaning they may never show any symptoms. Based on this information, the federal health agency is considering advising all Americans to wear masks, in a reversal of their previous stance.
“One of the [pieces of] information that we have pretty much confirmed now is that a significant number of individuals that are infected actually remain asymptomatic,” CDC director Dr. Robert Redfield told NPR on Tuesday.
“That may be as many as 25 percent. That’s important, because now you have individuals that may not have any symptoms that can contribute to transmission, and we have learned that in fact they do contribute to transmission,” he added.
According to Redfield, COVID-19 has the ability to transmit far easier than flu, and it is “probably now about three times as infectious as the flu.”
Fauci added that their main concern with a policy like that is making sure they are not taking supplies away from health care workers, who have repeatedly expressed a shortage in personal protective equipment across hospitals and medical facilities in the U.S.
“But when we get in a situation where we have enough masks, I believe there will be some very serious consideration about more broadening this recommendation of using masks,” he added. “We’re not there yet, but I think we’re close to coming to some determination.”
In the meantime, Redfield reminds Americans that their most “powerful weapon” against contracting the virus and spreading it is to continue social distancing.
“This virus cannot go from person to person that easily. It needs us to be close. It needs us to be within 6 feet. If we just distance ourselves, this virus can’t sustain itself and it will go out,” he said. “So this social distancing that we’re pushing, is a powerful weapon, and that will shut this outbreak down sooner than it otherwise would have been shut down.”
“I’d like to thank all the Americans and all the people in our nation that have taken this to heart and really practice aggressive social distancing,” he added.
Redfield and the CDC predict for now that the U.S. should see a decline in the virus late spring and early summer, but warns this will be a seasonal occurrence with a second wave expected to hit in the fall and winter.
“As next season comes up, it’s going to be important that we reembrace that social distancing,” Redfield said.
