This negative-stained transmission electron micrograph (TEM) depicted a number of influenza A virions. There are three types of influenza viruses: A, B and C. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. The emergence of a new and very different influenza virus to infect people can cause an influenza pandemic. Influenza type C infections cause a mild respiratory illness and are not thought to cause epidemics. For a colorized version of this image see PHIL 11702. IMGSETINF. Image courtesy CDC/F. A.
