West Nile virus, TEM
West Nile virus particles. Coloured transmission electron micrograph (TEM) of West Nile virus (WNV) particles (green) next to a host cell (red). This virus causes encephalitis (inflammation of the brain) in humans. The WNV belongs to the group of Flaviviruses, which are RNA viruses that have a core (dark) surrounded by an outer protein coat (green) with a cubic symmetry. WNV is transmitted by mosquitoes and infects both humans and animals. Symptoms can range from a mild fever to spontaneous bleeding of the skin and circulatory failure, which are often fatal. WNV occurs in Africa, Asia, Europe and North America

EDITORS COMMENTS
This print from Science Photo Library showcases the West Nile virus, a microscopic menace that causes encephalitis in humans. The image reveals the intricate structure of this RNA virus, belonging to the Flavivirus group. In vibrant colors, we see the West Nile virus particles depicted in green, juxtaposed next to a host cell shown in red. The dark core of the virus is surrounded by an outer protein coat with a cubic symmetry. This visual representation provides valuable insights into its morphology and composition. Transmitted through mosquito bites, WNV can infect both humans and animals across continents like Africa, Asia, Europe, and North America. Symptoms resulting from WNV infection vary widely; they range from mild fever to severe complications such as spontaneous bleeding of the skin and circulatory failure – often proving fatal. As seen under transmission electron microscopy (TEM), these viral particles are actively replicating within their host cells. This remarkable photograph not only highlights the beauty found within scientific imagery but also serves as an important tool for medical research and understanding pathogenic microorganisms. It sheds light on virology, microbiology, pathology while emphasizing the significance of studying infectious diseases like West Nile virus to safeguard public health worldwide.
