National Enterovirus Surveillance System (NESS)

The National Enterovirus Surveillance System (NESS) is a passive, voluntary surveillance system that monitors laboratory detections of enteroviruses and parechoviruses in the United States. Participating laboratories report basic specimen data, including serotype. Public health practitioners, researchers, and clinicians have used NESS data since the 1960s to determine circulation patterns of individual enterovirus and parechovirus types.

NESS uses REDCap to collect electronic data on types of enteroviruses and parechoviruses from laboratories across the U.S.

See the latest data from NESS, including the most commonly reported enteroviruses and parechoviruses from participating laboratories each year.
