Rotavirus is spreading in New Jersey

Key Points:

• Rotavirus cases are spiking in parts of New Jersey, particularly Monmouth and Somerset counties, as detected through wastewater samples collected from January to April, reflecting a national increase especially in the Northeast.
• The virus mainly affects infants and young children, causing severe vomiting and diarrhea that can lead to dehydration; early treatment focusing on rehydration is crucial to prevent hospitalization.
• The resurgence may be linked to reduced childhood immunizations and weakened immune systems due to less exposure to infectious diseases during the pandemic, with the virus spreading easily in hospitals and childcare centers.
• Wastewater surveillance, used by the CDC and managed by programs like WastewaterSCAN, provides rapid, community-level monitoring of rotavirus and other pathogens without requiring direct testing of individuals.
• Health officials emphasize vaccination as the most effective protection against rotavirus, alongside proper handwashing with soap and water, since hand sanitizer does not eliminate the virus; reinfections remain possible despite vaccination or prior infection.
