Global study maps how trade and travel fuel the worldwide spread of disease-carrying mosquitoes

Researchers compiled the first global database tracing how, when, and where non-native mosquito species that transmit human diseases have spread and established. The study reveals accelerating introductions since 1950, driven by trade, transport, and socio-environmental factors, highlighting actionable hotspots for global surveillance.

First global standard published to measure outcomes in dengue treatment trials

The first global standard which harmonizes what outcomes to measure in dengue treatment trials has been published this week in The Lancet Infectious Diseases. Co-led by researchers at King's and the University of Oxford, this solves a longstanding discrepancy in terms of what is measured in these trials.

Survey shows low public concern despite rising West Nile virus infections in the U.S.

West Nile virus is the leading cause of mosquito-borne illness in the continental United States. As of Sept. 23, over 1,100 human cases of West Nile disease have been reported across 42 states, according to the U.S. Centers for Disease Control and Prevention (CDC), including nearly 750 cases of the more serious neuroinvasive form which affects the brain.
