# # # 1. **Human Metapneumovirus (HMPV)**
* **Overview**: HMPV is a respiratory virus causing symptoms similar to the common cold or flu, such as cough, fever, congestion, and sore throat. ([New York Post][1])
* **Current Status**: Recent surges in HMPV cases have been reported in both China and the United States. In the U.S., cases have been increasing since November, with the CDC noting a rise in HMPV infections. ([New York Post][1])
* **Impact**: While most infections are mild, HMPV can lead to severe illness in young children, older adults, and immunocompromised individuals. There is currently no vaccine or specific treatment for HMPV; management focuses on supportive care. ([New York Post][1])
