There are several respiratory viruses going around, including:
-
HMPV: Human metapneumovirus, a little-known respiratory virus that surged in the US in March 2023. It is seasonal, like the annual flu, and levels have dropped since then. Symptoms are similar to the common cold.
-
RSV: Respiratory syncytial virus, which is expected to circulate in the US over the next few months along with influenza and COVID-19.
-
Influenza: The flu, which is also expected to circulate in the US over the next few months along with RSV and COVID-19.
-
COVID-19: The coronavirus disease, which continues to circulate globally and has several variants.
-
Enterovirus: A virus that can cause an array of symptoms, including congestion, runny nose, sore throat, and mouth sores.
-
Chickenpox: A viral illness caused by varicella zoster virus, which is very contagious.
The National Respiratory and Enteric Virus Surveillance System (NREVSS) is a laboratory-based system that monitors temporal and geographic circulation patterns of several respiratory viruses, including RSV, HMPV, and influenza.
