Due to the fact that the majority of people who are infected with COVID-19 don't ever experience symptoms, it can be difficult to determine whether or not someone is contagious. Unlike other illnesses, just because someone looks or feels good, they can still infect others with coronavirus. During an interview with MSNBC, Dr. Anthony Fauci, the nation's go-to infectious disease expert revealed the secret to knowing if you are still able to spread the virus. Read on, and to get through this pandemic at your healthiest, don't miss these Sure Signs You've Already Had Coronavirus.

Trump "Looks Good" But You Never Know

When asked about President Donald Trump's health after testing positive for the virus last week, Fauci revealed that answer is complicated. 

"He certainly looks good and apparently feels good," he said. "One of the issues that we all have to be aware [of], and his physicians are aware of this, is that the history of COVID-19 is that you could look and feel like you're doing reasonably well. And after a couple of days, you could have a downturn, namely having a reversal. That's possible. The chances of that happening, I don't know as good as he looks, I don't think that's going to happen, but I don't know, but you have to be heads up that it might happen."

And, even though he has received treatment and feels better, he is likely still in the infectious stage of the virus. Why? Infectiousness has less to do with how someone feels and more to do with science.

There's One Way to Prove Someone is Not Contagious

"The general guideline from the CDC says that 10 days from the onset of symptoms you can essentially consider someone non-infectious," he points out. One way to "definitively" prove that someone is no longer capable of spreading the virus is via "two negative PCR tests, 24 hours apart."

"So if the president goes 10 days without symptoms and they do the tests that we were talking about, then you can make the assumption based on good science that he is not infected," Fauci continued. "But you just have to wait and make sure you go through those particular benchmarks that are delineated in the CDC guidelines." As for yourself, avoid crowds, social distance, only run essential errands, wash your hands frequently, and to get through this pandemic at your healthiest, don't miss these 35 Places You're Most Likely to Catch COVID.
