Researchers reveal m6A epigenetic modification controls arbovirus infection and transmission

Arthropod-borne viruses (arboviruses), such as dengue and Zika viruses, transmit widely across the globe, posing threats to human health and biosecurity. They spread through the bites of arthropod vectors, moving between insects and vertebrate hosts. To sustain their transmission cycle, these viruses must alternately infect both mosquito vectors and vertebrate hosts.
