One thing to be on the lookout amidst all of the eclipse excitement -- diseases. No, not from the moon, but rather from all the people flocking to New York.

The Buffalo area alone is expected to see up to 1.2 million tourists, and if there's anything we learned from 2020, it's that large crowds can spread diseases.

The New York State Department of Health says COVID and flu cases are pretty low right now, but the main concern is norovirus. That's a highly contagious gastrointestinal disease that can spread through air and through touch.

"The good news about this event is that most infectious agents transmit best in indoor settings, particularly respiratory viruses. Most of us are going to be outdoors, at least for a large part of this. So that’s going to minimize risk," Dr. Thomas Russo, professor and chief of infectious disease at the University at Buffalo, said.

Experts recommend that anyone at risk to watch the eclipse in smaller groups and you can always wear a mask if you like.
