Dr. Sanjay Gupta: It's hard to say how far we are into this pandemic. Some of us have been socially distancing for weeks -- others started more recently.
By now, hopefully, those who can are staying at home. Which might mean you have more time than ever to follow news about the coronavirus and question what the future holds.
You've sent me a lot of your questions in emails and voice memos -- today, I want to spend some time answering them.
I'm Dr. Sanjay Gupta, CNN's Chief Medical Correspondent. And this is "Coronavirus: Fact vs. Fiction."
Listener: With so many people touching fresh produce and packages at grocery stores and markets, what measures need to be taken in protecting consumers from contracting the novel coronavirus?

Listener: I'm one of the nurses here in Las Vegas. How can we be safe in taking care of the ill if we ourselves aren't protected properly?
Dr. Gupta: The answer is: You can't. That's why this question is crucial and will become even more so as our hospitals attempt to handle
