RM2BE0J6R–Transmission electron micrograph (TEM) of influenza A virus.

H3N2 influenza virus particles, coloured transmission electron micrograph (TEM). Each virus consists of a nucleocapsid (protein coat) that surrounds a core of RNA (ribonucleic acid) genetic material. Surrounding the nucleocapsid is a lipid envelope that contains the glycoprotein spikes haemagglutinin (H) and neuraminidase (N). These viruses were part of the Hong Kong Flu pandemic of 1968-1969 that killed approximately one million worldwide. H3N2 viruses are able to infect birds and mammals as well as humans.

Transmission Electron Micrograph (TEM) of Influenza A. Influenza A virus causes influenza in birds and some mammals, and is the only species of influenza virus A. Influenza virus A is a genus of the Orthomyxoviridae family of viruses. Strains of all subtypes of influenza A virus have been isolated from wild birds, although disease is uncommon. Some isolates of influenza A virus cause severe disease both in domestic poultry and, rarely, in humans. Occasionally, viruses are transmitted from wild aquatic birds to domestic poultry, and this may cause an outbreak or give rise to human influenza pan

RMBDMMPP–Negative-stained transmission electron micrograph (TEM) of a number of influenza virus particles

Colorized transmission electron micrograph (TEM) of the A/New Jersey/76 (Hsw1N1) virus, while in the virus' first developmental passage through a chicken egg. Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza that regularly cause outbreaks of influenza among pigs. Swine flu viruses cause high levels of illness and low death rates among pigs. Swine influenza viruses may circulate in swine throughout the year, but most outbreaks among swine herds occur during the late fall and winter months similar to humans. The classical swine flu virus (an influenza type
