Coloured TEM of yellow fever viruses
Yellow fever virus. Coloured transmission electron micrograph (TEM) of yellow fever viruses, cause of yellow fever. Although the viruses coloured green appear rounded here, they are of cubic symmetry. They are of the Flavivirus group, containing RNA genetic material. The yellow fever virus occurs in tropical Africa, Central and South America. It is transmitted to humans when an infected female mosquito Aedes aegypti bites a human. Yellow fever causes yellowing of the skin due to jaundice. Other symptoms include fever, headache and nausea. In serious cases there may be liver and kidney damage, and even death. Yellow fever vaccines provide immunity. Magnification: unknown

EDITORS COMMENTS
This print showcases a coloured transmission electron micrograph (TEM) of yellow fever viruses, the notorious cause of yellow fever. The green-coloured viruses, although appearing rounded in this image, possess cubic symmetry. Belonging to the Flavivirus group and containing RNA genetic material, these microscopic entities are responsible for outbreaks in tropical Africa, Central and South America. The transmission of yellow fever occurs when an infected female mosquito known as Aedes aegypti bites a human host. This viral infection leads to various distressing symptoms such as jaundice-induced skin yellowing, high fever, severe headaches, and nausea. In more severe cases, it can result in liver and kidney damage or even prove fatal. Thankfully, science has provided us with effective protection against this deadly virus through yellow fever vaccines that confer immunity. However, the magnification level used to capture this stunning image remains unknown. This remarkable photograph serves as a reminder of the intricate world hidden from our naked eyes but brought into focus by advanced scientific techniques. It is courtesy of Science Photo Library's collection on viruses belonging to the flavivirus family and specifically highlights the infamous yellow fever virus – an entity that continues to challenge medical professionals worldwide.
