Health officials are closely monitoring a shift in seasonal illnesses across Franklin County this week. While the mid-winter peak of respiratory viruses appears to be cooling, the Centers for Disease Control and Prevention and the Pennsylvania Department of Health report that the region remains in a “moderate” activity zone for several key illnesses.
The “big three” respiratory viruses
According to the latest CDC FluView and state surveillance data, the trio of Influenza, COVID-19, and RSV continues to be the primary driver of doctor visits in South Central Pennsylvania.
- Influenza (flu): There is a notable transition occurring in the virus strains. While Influenza A (H3N2) has dominated the season, the CDC is now reporting an uptick in Influenza B cases. This “second wave” of Type B is common in late February and can sometimes lead to a prolonged flu season.
- COVID-19: Activity is currently described as “decreasing slightly” across the state. However, wastewater surveillance in Pennsylvania still shows moderate levels of the virus, and hospitalizations remain steady among older adults and those with underlying conditions.
- RSV: After a high-intensity start to the year, RSV cases are beginning to decline. However, the CDC warns that pediatric units are still seeing a significant number of infants and toddlers seeking care for RSV-related bronchiolitis.
Measles alert in neighboring counties
While not a widespread outbreak in Franklin County, local health providers are on high alert following the confirmation of measles cases in nearby Lancaster County earlier this month. The CDC has emphasized that 97% of recent national cases occur in unvaccinated individuals. Local residents are encouraged to verify their MMR (Measles, Mumps, and Rubella) vaccination status, especially if planning travel.
Norovirus and “stomach flu”
Anecdotal reports from local school districts align with national CDC trends showing an increase in Norovirus—the highly contagious virus that causes vomiting and diarrhea. Unlike respiratory viruses, Norovirus is resistant to many hand sanitizers; officials stress that vigorous handwashing with soap and water is the only effective way to stop its spread in households and classrooms.
