Flaviviruses are a group of positive-sense single-stranded RNA viruses that are primarily transmitted by arthropods, such as mosquitoes and ticks. These viruses can cause a range of diseases in humans, including dengue fever, Zika virus, yellow fever, and West Nile virus. Flaviviruses are a significant public health concern due to their potential to cause widespread outbreaks and severe illness. Research on flaviviruses focuses on understanding their biology, transmission mechanisms, and developing effective prevention and control strategies, such as vaccines and vector control measures. Additionally, ongoing research aims to discover novel therapeutic approaches to combat flavivirus infections and reduce their impact on global health.
