- Influenza A: Avian flu H5N1, swine flu H1N1
Definitions
- Human influenza is RNA virus, categorized into types A, B and C, which can be subcategorized into several subtypes, e.g., influenza A: H1N1, H1N2, H2N1, H3N1, etc.; influenza B subtypes are B/Yamagata and B/Victoria lineages
- Influenza pneumonia results from lung inflammation and compromise caused by direct viral infection of respiratory epithelium
