Nairovirus is a genus of viruses belonging to the family Bunyaviridae. These viruses are primarily transmitted by ticks and can infect various animal species, including livestock. Nairoviruses are known to cause diseases such as Crimean-Congo hemorrhagic fever and Nairobi sheep disease, which can lead to significant health issues in both animals and humans. The symptoms of nairovirus infections can vary widely, ranging from mild fever to severe hemorrhagic manifestations. Prevention strategies focus on controlling tick populations and minimizing contact between infected animals and humans. Research continues to better understand these viruses and develop effective vaccines and treatments.
