Flaviviruses are a group of positive-sense single-stranded RNA viruses that belong to the Flaviviridae family. They are characterized by their icosahedral capsid and a lipid envelope. Flaviviruses are known for their ability to infect a wide range of hosts, including humans, birds, and mammals. They are transmitted through various means, such as mosquitoes, ticks, and direct contact.

The genus Flavivirus includes several well-known viruses, such as the dengue virus, yellow fever virus, West Nile virus, and Japanese encephalitis virus. These viruses cause a range of diseases, from mild to severe, including fever, rash, and neurological symptoms. Flaviviruses are also associated with serious conditions like dengue fever, which can lead to severe bleeding and shock, and yellow fever, which can cause jaundice, bleeding, and even death.

Flaviviruses are of significant medical and veterinary importance due to their potential to cause outbreaks and pandemics. They are also a subject of ongoing research for the development of vaccines and antiviral therapies. The study of flaviviruses involves molecular biology, virology, and epidemiology to understand their replication, transmission, and control.
