Romania faces growing mosquito-borne disease threat as climate shifts

Romania faces a growing threat from mosquito-borne diseases as climate change creates favorable conditions for tropical disease vectors, according to epidemiologist Emilian Popovici, who warns the country must prepare for illnesses historically associated with tropical regions. West Nile virus is already an active annual risk, with Romania ranking among Europe's top three affected countries alongside Italy and Greece, reporting 45 local cases across 15 affected zones by August 26, 2026. The Asian tiger mosquito (Aedes albopictus) is established in 10 of Romania's 42 administrative units, creating conditions for potential local dengue and chikungunya transmission. Popovici states that local outbreaks of dengue or chikungunya are "only a matter of time," dependent on viremic travelers entering the country during July-August. He recommends integrated vector management strategies, advanced surveillance systems, and public education campaigns, noting current mosquito control measures based solely on local spraying have limited effectiveness.
