Arboviruses, or viruses carried by arthropods like mosquitoes or ticks, are responsible for hundreds of thousands of deaths worldwide each year. As the climate changes globally, the geographic distribution of these diseases, including Zika, dengue, chikungunya, West Nile, and yellow fever, are steadily expanding. The National Academies Forum on Microbial Threats hosted a public workshop in December 2023 to explore avenues of threat reduction from known and emerging arboviral diseases in the context of public health preparedness and capacity building. The workshop featured talks from experts in entomology, public health, ecology, virology, immunology, disease modeling, and urban planning.
