NIH scientists show in mice that "stomach viruses" spread through saliva

June 29, 2022

A study published in the scientific journal Nature on determind that in mice, stomach viruses such as norovirus can be spread through saliba, which represents a new route of transmission for these diarrhea-producing viruses. These findings are not yet confirmed in humans.

"The transmission of these so-called enteric viruses through saliva suggests that coughing, talking, sneezing, sharing food and utensils, and even kissing all have the potential for spreading the viruses. The new findings still need to be confirmed in human studies. "
