As winter slowly fades away, the threat of viral infections remains prevalent across the United States. Recent data from WastewaterSCAN, a network monitoring wastewater surveillance sites, highlights the resurgence of several viruses, signaling that the sick season is far from over. Here’s a breakdown of the viruses causing concern right now:
Norovirus:
Known as the “cruise ship virus,” norovirus is highly contagious and a common cause of food-borne illnesses in the U.S. Its prevalence typically peaks from November to April, and this year is no exception. While infections usually decline by late February, the recent data suggests a prolonged peak, emphasizing the need for continued vigilance in sanitation practices, especially in high-traffic areas like kitchens and bathrooms.
Human Metapneumovirus (HMPV):
Despite being identified only recently in 2001, HMPV has quickly emerged as a respiratory threat, particularly affecting older individuals and young children. Recent wastewater sampling indicates a sharp increase in HMPV cases since late February, underscoring its late-season surge. While no specific antiviral treatment exists, adhering to basic hygiene measures can help mitigate its spread.
Influenza B:
While influenza A viruses are on the decline, influenza B viruses are on the rise and have recently peaked. This contrasts with the previous year, indicating a shift in the dominant strains. Although the annual flu shot offers protection against both influenza A and B viruses, individuals should remain diligent in practicing good hygiene habits.
Wastewater surveillance provides valuable real-time insights into viral trends, guiding public health responses and vaccine development strategies. This evolving tool not only aids in monitoring known pathogens but also holds promise for detecting emerging threats in the future. As we navigate through these ongoing challenges, staying informed and proactive remains crucial in safeguarding public health.
By leveraging the data provided by WastewaterSCAN and adhering to recommended preventive measures, we can collectively combat the persistence of these viral threats and pave the way for a healthier future.
Remember, while we may be tired of the pandemic, viruses don’t adhere to calendars. Stay vigilant, stay safe.
