Abstract:

Mosquito-borne viruses transmit between hosts and mosquito carriers through mosquito biting, which cause hundreds of millions of infections each year. These viral infections result in serious human diseases such as hemorrhagic fever, biphasic fever, arthritis, encephalitis and meningitis, which can lead to death if proper treatment is not available. Most mosquito-borne viruses are RNA viruses, with the flavivirus family as the most prevalent ones, including dengue virus, Zika virus, yellow fever virus, Japanese encephalitis virus and West Nile virus. Although there are effective vaccines for a few mosquito-borne flaviviruses, such as those for yellow fever virus and Japanese encephalitis virus, there are still no effective preventive vaccines and antiviral therapies for most mosquito-borne flaviviruses. Therefore, a comprehensive understanding of the mechanisms underlying the infection and transmission of mosquito-borne flaviviruses between vertebrate hosts and mosquitoes would provide insights for vaccine and drug development, enabling us to more effectively predict and control the transmission of mosquito-borne flavivirus and occurrence of the epidemics in the future, and providing solutions for addressing the public health threats posed by arboviruses. In this article, we firstly describe the biological and epidemiological characteristics of mosquito-borne flaviviruses, introduce the transmission routes and carrier models of mosquito-borne flaviviruses, and summarize the current research on the transmission and infection mechanisms of mosquito-borne flaviviruses between hosts and carriers. Furthermore, we highlight the development of novel vaccines and strategies for screening drugs to fight against mosquito-borne flaviviruses, providing an outlook for future research and development of vaccines and antiviral drugs.

Key words: mosquito-borne flavivirus, mosquito vector, infection and transmission, pathogenesis, vaccine and drug
