Influenza A, COVID-19 and norovirus (stomach flu) are on the rise, according to the Centers for Disease Control and Prevention. But there’s a fourth “bug” the public should be aware of: respiratory syncytial virus. RSV causes cold-like symptoms and affects the breathing passages and lungs.
Wastewater levels of RSV are “moderate” nationwide for the week ending Dec. 28, according to the CDC’s wastewater monitoring systems. Wastewater levels of RSV rose to moderate in mid-December – the first time it reached moderate since January 2024. Since then, RSV levels in wastewater had been “minimal” or “low,” according to the CDC.
Respiratory viruses can spread quickly in winter months, as more people spend time inside. Colder temperatures can weaken your immune system, and colder, drier air can help respiratory viruses thrive, experts say.
