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 are encouraged to 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.
|Enterovirus||Percentage of Positive Specimens|
|1 Enterovirus D68||55.9% of specimens|
|2 Echovirus 30||5.8% of specimens|
|3 Coxsackievirus A6||5.5% of specimens|
|4 Echovirus 18||4.2% of specimens|
|5 Coxsackievirus B3||4.0% of specimens|
|6 Echovirus 9||2.4% of specimens|
|7 Echovirus 11||2.3% of specimens|
For more information about the most recent enterovirus data, see CDC MMWR Enterovirus and parechovirus surveillance, United States, 2014–2016.
NESS accepts electronic reports of enterovirus and parechovirus typing results. If your laboratory is interested in participating, please contact us.
