Nairoviruses are a group of viruses belonging to the family Bunyaviridae. They are primarily transmitted by ticks and can infect both animals and humans. These viruses are known to cause various diseases, including Crimean-Congo hemorrhagic fever, which can lead to severe illness and high mortality rates. The main hosts of nairoviruses are often livestock, such as sheep and cattle, which can serve as reservoirs for the virus. Prevention strategies focus on controlling tick populations and monitoring animal health to reduce the risk of transmission to humans.
