The Junta de Andalucía confirms five mild cases of West Nile virus in the province of Seville, located in four municipalities. All affected individuals show mild symptoms and no hospitalisations have been recorded.
The Ministry of the Presidency, Health and Emergencies of the Junta de Andalucía has confirmed five mild cases of West Nile virus in the province of Seville during the current season. The positive cases have been detected in four municipalities in Seville, keeping the province as the main focus of surveillance against this mosquito-borne disease.
According to the latest epidemiological report, the cases have been located in Palomares del Río, Villamanrique de la Condesa, La Puebla del Río, and Coria del Río. In Palomares del Río, two of the five cases recorded this year have been noted. All affected individuals present mild symptoms and have not required hospitalisation, according to health sources.
The Junta's surveillance system has analysed 262 individuals, conducted arbovirus screening in 104 patients with viral meningitis, and performed 950 tests in blood donor screening, all with negative results for the West Nile virus. These figures reflect a thorough control effort to detect possible asymptomatic or mild cases.
The epidemiological update coincides with an increase in municipalities on alert due to the circulation of the virus. This Sunday, the Junta added San Juan de Aznalfarache to the list of localities with confirmed presence of the virus in mosquitoes captured near the urban area. Additionally, the alert situation in Palomares del Río, where carrier mosquitoes had already been detected, has been extended.
The surveillance systems have also detected the circulation of the virus in two wild birds located around the Doñana National Park, an area of special ecological sensitivity. So far, no positives have been recorded in equines during the current season, indicating that the virus primarily circulates through mosquitoes and birds.
The Junta maintains active vector control protocols in the affected municipalities, with fumigation and public awareness campaigns to reduce exposure to mosquito bites. Authorities recommend that the population use repellents, mosquito nets, and avoid standing water accumulations, especially during peak mosquito activity hours, at dawn and dusk.
For residents of the municipalities in Seville with confirmed cases, the main recommendation is to visit the health centre if symptoms such as fever, headache, or general malaise occur, although most mild cases resolve without complications. The Ministry of Health reminds that West Nile fever is not transmitted from person to person, but only through the bite of infected mosquitoes.
The West Nile virus is endemic in southern Spain and typically appears between July and October, coinciding with high temperatures and rains that favour mosquito breeding. In previous years, outbreaks have been recorded in the province of Seville, with severe cases occurring on some occasions. Health authorities stress the importance of prevention and continuous monitoring to minimise the impact of the disease.
The Junta de Andalucía will continue to provide periodic updates on the evolution of the situation and the measures taken. Citizens can consult official recommendations through the public health channels of the regional administration.
