Respiratory Virus Surveillance Dashboard

April 28, 2022: Recent trends in reported case rates by vaccination and booster status have become difficult to interpret due to a number of factors, including: higher prevalence of previous infection among the unvaccinated and un-boosted groups; difficulty in accounting for time since vaccination and waning protection; and potential biases related to differences in testing practices (e.g., at-home tests) and prevention behaviors. Therefore, attack rates and ratios by vaccination status are no longer being included in the weekly Respiratory Virus Surveillance Summary report. These factors are likely to impact differences in mortality rates by vaccination status but to a lesser degree.

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

Respiratory Virus Surveillance Summary will be updated every Thursday by 4 p.m.

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).
