CDC Reports Rise in Norovirus Cases in New Mexico

New Mexico – Norovirus cases, a highly contagious stomach bug, are on the rise across the U.S., including in New Mexico, according to recent data from the U.S. Centers for Disease Control and Prevention (CDC). The New Mexico Department of Health (NMDOH) has expressed concern over the increasing number of cases, particularly as the holiday season brings more gatherings.

Dr. Chad Smelser, the deputy state epidemiologist for NMDOH, noted that reports from the CDC indicate a rise in cases since late October, continuing through November and December. “It was disrupted a bit during the pandemic due to isolation and precautions, but now it’s returning, similar to what we saw before COVID-19,” Smelser explained.

CDC data from 14 states shows that 91 outbreaks of norovirus were reported during the week of December 5, up from 69 outbreaks in the week of November 28. In New Mexico, four outbreaks have been identified, all occurring in long-term care facilities, though Smelser suspects there may be more unreported cases. He added that this year’s viral activity could reach pre-pandemic levels of spread.

Norovirus typically causes symptoms such as nausea, vomiting, and diarrhea. While it is more common in winter, the NMDOH warns that its spread has increased due to higher social interactions during the holiday season. To prevent infection, Smelser emphasized the importance of handwashing and avoiding contact with sick individuals. He also advised that anyone showing symptoms of norovirus should refrain from preparing food for others and isolate themselves as much as possible.

Symptoms typically appear 24 to 48 hours after exposure. If symptoms last longer than three days or become severe, the NMDOH recommends seeking medical attention.
