Influenza viruses circulate year-round, but the number of new influenza cases generally increases in the cooler months and tapers off in the warmer months of the year. Both viruses depend on a viral RNA polymerase to express their proteins, but only SARS-CoV-2 has a proofreading mechanism, which results in a low mutation rate compared to influenza. The Taxonomy Database is a curated classification and nomenclature for all of the organisms in the public sequence databases. Influenza A viruses are divided into subtypes on the basis of two proteins on the surface of the virus: hemagglutinin (HA) and neuraminidase (NA).

There are 18 known HA subtypes and 11 known NA subtypes. Its virions show spherical or filamentous shapes of about 100 nm in diameter and occasionally irregular morphology, which exemplifies the pleomorphic nature of these virions. 129 Lineage(full): Viruses; Riboviria; Orthornavirae; Negarnaviricota; Polyploviricotina; Insthoviricetes; Articulavirales; Orthomyxoviridae; Betainfluenzavirus.
