"This helps explain how rapidly this virus continues to spread across the country, because we have asymptomatic transmitters and we have individuals who are transmitting 48 hours before they become symptomatic", Dr. Redfield said in the interview.
Many officials from around the world have claimed that wearing masks is unnecessary especially those who are non-symptomatic of the COVID-19 virus.
For weeks, Americans were told that the general public does not need to wear masks while in the public.
"I think I took it really out of curiosity to see how quickly it worked", said Trump, who also tested negative last month after coming into contact with a Brazilian official who later tested positive for the coronavirus.
Trump emphasized that the CDC isn't recommending the use of commercial medical-grade masks, which are in short supply at hospitals.
If you wear a homemade cloth mask, scarf or bandana, do not forget to wash your hands before you put it on, Adams said.
After dragging his heels about advising Americans to wear a cloth mask in public to help stem the spread of the COVID virus, President Donald Trump announced on April 3 that the CDC is recommending Americans do so.
Earlier Friday, the CEO of 3M went on television to deny that his company has done anything wrong and said 3M is doing all it can to fight price gouging and unauthorized resale, and that the company is increasing its production.
Trump also said that mask-wearing did not replace the social distancing guidelines the government already put out, including standing six feet apart and "practicing hand hygiene" as the president put it. The number of cases has continued to rise with over 200,000 positive patients, while more than 7,000 deaths have been recorded so far in the US. "I somehow don't see it for myself". Scarves work just as well, he said.
"The CDC is advising the use of non-medical cloth-based covering".
And on Thursday, officials in Laredo, Texas, issued an emergency ordinance which means residents will face a $1,000 (£815) fine if they fail to cover their noses and mouths while outside.
