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."

      Question 1

        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?
        Dr. Gupta: Now, it's important to point out that coronavirus is not a food-borne illness, but a respiratory illness. You won't get it from eating food. But experts do recommend wiping down the outsides of canned or wrapped goods. You should be washing your produce anyway, so keep doing that. You should also be sure to wash your hands after unpacking your groceries.
        You know the drill: soap and water for 20 seconds. Don't forget your thumbs.

They're all very interconnected. So, my question is, if someone does get exposed and get sick, how can they best self-isolate while still under the same roof?
        Dr. Gupta: This is a hard one. If an infected person lives in a shared space, that person should try to keep to a single room as much as possible. The Centers for Disease Control and Prevention have a really helpful home care guide that suggests steps for those living with a sick person.
        Some of the recommended precautions include making sure shared spaces have good air flow, having the sick person wear a mask if they're able to, and using disposable gloves to handle potentially contaminated items like tissues or dishes.

        Question 3

        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
