The C Influenza Virus is one of the three main types of influenza viruses, alongside A and B. It primarily infects humans and some animals, causing mild respiratory illness. Unlike A and B, which can lead to seasonal epidemics, C typically results in less severe symptoms and does not cause widespread outbreaks. C Influenza Virus is characterized by its ability to mutate, but it does so at a slower rate than A and B. Vaccines are not commonly developed for C due to its lower impact on public health. Overall, it remains a less significant concern compared to other influenza types.
