CLI Surveillance

Is North Carolina seeing a continued downward trajectory or sustained leveling of COVID-Like Illnesses (CLI) in its surveillance systems? 

COVID-19 Surveillance Summary will be updated every Thursday by 4 p.m. Please note this report was updated Wednesday, Nov. 25 due to the Thanksgiving holiday.

The North Carolina Department of Health and Human Services (NCDHHS) is using all available tools to monitor the spread of COVID-19 across the state. In addition to tracking and reporting of laboratory-confirmed cases, NCDHHS is using many of the same systems that are used to track influenza and other respiratory illnesses each season. 


Mild COVID-19 illness presents with symptoms similar to influenza-like illness, so surveillance systems that have historically been used during influenza seasons are being used to track trends of mild COVID-19 illness and allow for comparison with prior influenza seasons. Limitation: These numbers represent only people seeking care in the Emergency Department (ED).
