The Extremadura Health Service confirmed a further human case of West Nile fever in Extremadura on 11 September 2026. The person affected is a 67-year-old man from Miajadas (province of Cáceres), who, according to the regional government, does not need to be admitted to hospital and is receiving outpatient care.
The health authority attributes the increase in cases to the ongoing late-summer season, when the virus regularly circulates in south-western Europe. Several new infections had already been recorded in Extremadura in recent weeks. At the end of August and beginning of September, the Junta de Extremadura reported two deaths linked to the virus. The authority gave no information about any new severe cases in the current instance.
West Nile virus is usually transmitted by mosquitoes. According to current knowledge, it is not transmitted from person to person. According to the Servicio Extremeño de Salud, about 80 per cent of infections are asymptomatic. A smaller proportion result in febrile illness; neuroinvasive cases such as meningitis or encephalitis are rare, particularly affecting older people or those with pre-existing conditions.
The Junta de Extremadura points to its strengthened monitoring and control of vectors. These measures include expanded entomological surveillance in the worst-affected areas and cooperation with the University of Extremadura to identify mosquito species and test for the presence of the virus in laboratories. The aim is to detect chains of infection early and coordinate countermeasures in the areas where cases are detected.
As a precaution, the Servicio Extremeño de Salud recommends avoiding potential breeding sites: cover water containers and rain barrels, regularly empty plant saucers and other receptacles, and maintain gardens so that no standing water remains. The authorities advise people to use approved mosquito repellents, wear light-coloured clothing that covers the skin in the evening and at night, and fit mosquito screens to windows and doors. Doctors in the region have been asked to remain alert so that possible symptoms can be assessed promptly and laboratory-confirmed cases reported without delay.
The latest information comes from statements by the Junta de Extremadura and consistent reports in regional media on 11 September 2026, including Europa Press and Canal Extremadura.
