Influenza A and B viruses are responsible for respiratory epidemics each year. Influenza A Viruses are categorized by their surface proteins: Hemagglutinin (H) and Neuraminidase (N). Since Influenza B viruses are structurally different, they are only broken down into two lineages: B/Yamagata and B/Victoria (CDC, 2017).
The Delaware Public Health Lab performs influenza identification, molecular detection, and genotyping/subtyping. Influenza surveillance is performed as part of the CDC-World Health Organization (WHO) Influenza surveillance effort. This information, along with a select number of isolates, is provided to CDC and the WHO to aid in surveillance efforts and future vaccine formulation. THE INFLUENZA VACCINE IS NOT A GUESS!
