Abstract & Authors:展开
Mosquito-borne arboviruses are a group of heterogeneous viruses that are mainly transmitted to vertebrate hosts and are the aetiological agents of many human diseases. These viruses naturally maintain a life cycle between distinct hosts by transmission from an infected mosquito to a naive host, and acquisition from a viraemic host back to a fed mosquito. To survive in and maintain a cycle between different host environments, mosquito-borne arboviruses exploit sophisticated approaches, including subverting the immune system, hijacking host factors, and taking advantage of gut microbes. We summarize the recent progress towards understanding the mechanisms of arboviral transmission and acquisition by mosquitoes. This knowledge offers an insight into the emergence and re-emergence of arboviruses in nature and an avenue for disease prevention in the future.
