Three members of the White House's coronavirus task force, including Dr. Anthony Fauci, are quarantining themselves after coming into contact with someone who has tested positive for the coronavirus.

Stephen Hahn, commissioner of the Food and Drug Administration, and Robert Redfield, the director of the Centers for Disease Control and Prevention, have decided to self-quarantine for two weeks.

Since the beginning of the coronavirus outbreak in the U.S., officials have been warning about the prospect of a second wave. Some even say additional COVID-19 spikes in the country could be worse than the first wave.

Dr. Ali Khan, former director of the Office of Public Health Preparedness and Response at the Centers for Disease Control and Prevention, says he is confident that a second wave will happen. That's because, he says in an interview with NPR's Morning Edition, the vast majority of people in the U.S. are likely still at risk of contracting the virus.

The Centers for Disease Control and Prevention has added several new symptoms to its existing list of symptoms for COVID-19.

The CDC has long said that fever, cough and shortness of breath are indications that someone might have the disease caused by the novel coronavirus. It has now added six more conditions that may come with the disease: chills, repeated shaking with chills, muscle pain, headache, sore throat and new loss of taste or smell.

The Centers for Disease Control and Prevention is funding 650 health workers at state health departments to supplement more than 600 CDC staff already in place, according to director Dr. Robert Redfield.

It's the question on everyone's minds: What will it take for us to come out of this period of extreme social distancing and return to some semblance of normal life?

It turns out that the Centers for Disease Control and Prevention has been working on a plan to allow the U.S. to safely begin to scale back those policies. CDC Director Robert Redfield spoke with NPR on Thursday, saying that the plan relies on not only ramped-up testing but "very aggressive" contact tracing of those who do test positive for the coronavirus, and a major scale-up of personnel to do the necessary work.

The federal government has released new guidelines regarding when people in critical infrastructure roles can return to work after being exposed to a confirmed or suspected case of the coronavirus.

The guidance pertains to essential critical workers who have been exposed to COVID-19. For those individuals, the guidelines advise:

• Take your temperature before work.
• Wear a face mask at all times.

President Trump said Friday the Centers for Disease Control and Prevention now recommends that people wear cloth or fabric face coverings, which can be made at home, when entering public spaces such as grocery stores and public transit stations. It is mainly to prevent those people who have the virus — and might not know it — from spreading the infection to others.
