These viruses are typically transmitted through arthropod vectors, such as mosquitoes and ticks. Some well-known members of this family include the Dengue virus, Zika virus, and West Nile virus. The structure of 黄病毒科 viruses is characterized by a single-stranded RNA genome and an envelope derived from the host cell membrane. These viruses can lead to a range of illnesses, from mild fevers to severe conditions like hemorrhagic fever, making them significant public health concerns worldwide.
