Generally, someone with norovirus symptoms (severe vomiting and/or diarrhea) should stay home until at least a full 48 hours after their symptoms have ended because that’s the time that they’re shedding the highest amount of virus. In reality, someone with noro could spread the virus for up to two weeks afterward or even longer. If we excluded everyone for the full amount of time they shed the virus, it would be a huge financial burden, so it’s not realistic. But the good news is that good hand hygiene can prevent the spread of noro and drastically reduce the risk of an outbreak. It’s very important to make sure your employees don’t return until they’ve been symptom-free for a minimum of two full days and that they’re hyper-focused on hand washing, especially the first week after they return.

Public health officials are concerned after former president Donald Trump said earlier this week that he wouldn’t give “one penny” to any schools with vaccine or mask mandates. Right now, every single state and D.C. have vaccine mandates for routine childhood immunizations that prevent devastating diseases like polio, mumps, measles, and whooping cough. If federal funding were withheld from schools that require vaccination, it would have a massive impact. If routine childhood vaccination requirements were removed, public health experts fear we’d see the return of dangerous diseases that they’ve worked for generations to eliminate in the U.S., like polio. Trump’s campaign spokesperson said in an email to a Hill reporter that he’s only referring to COVID vaccines, which is reassuring. Still, politicization and polarization of vaccines is likely to cause continued drops in routine childhood vaccination uptake.

Norovirus is particularly hard to kill because it has a strong protein shell called the capsid that surrounds its core. A quick squirt of hand sanitizer isn’t usually enough to break that strong shell and destroy the virus. In fact, even hand washing needs to be vigorous to kill noro. It takes 30 full seconds of washing with hot water and soap, including the backs of the hands and under the nails. If you have noro in your community, or if you have an employee who is just returning 48 hours after their noro-like symptoms ended, it’s important to reiterate just how important very thorough hand washing is for preventing the spread.
