Sunday, August 25, 2024 Spanish health authorities have issued a warning following a recent spike in West Nile virus infections, with 13 new cases confirmed this week. The virus appears to be spreading particularly in the Sevilla and Huelva regions, causing concern among public health officials. Six of the newly reported cases were found in Dos Hermanas, a town just a few kilometers from Sevilla.
In addition, three cases have been recorded in Coria del Rio, with one case each reported in La Puebla del Rio, Mairena del Aljarafe, and Alcala de Guadaira. Another case was confirmed in Campofrio, located in Huelva province. West Nile virus can cause a range of symptoms.
Approximately 20% of those infected experience mild symptoms such as vomiting, rashes, and body aches. However, in more severe cases, the virus can lead to seizures, muscle weakness, paralysis, and even life-threatening complications like meningitis and encephalitis, often requiring hospitalization. The European Centre for Disease Prevention and Control (ECDC) highlighted the threat posed by the virus last year when 713 cases were reported across nine European countries, resulting in 67 deaths.
The virus also spread to 22 new regions that had not previously reported infections, underscoring its growing reach. Countries such as Italy, Greece, Romania, Hungary, and Spain were identified as hotspots for West Nile virus last year. The virus is particularly dangerous for individuals over 50 and those with underlying health conditions like diabetes, high blood pressure, and cancer, who are at a higher risk of severe symptoms.
Health authorities are attributing the rise in West Nile virus cases to increased mosquito activity, which is the primary vector for transmission. The Ministry of Health has advised the public to take preventative measures to protect against mosquito bites, especially during the peak risk periods around dawn and dusk. Recommendations include applying mosquito repellent, wearing light-colored clothing that covers the skin, and using mosquito nets when possible.
The Junta de Andalucía’s Ministry of Health has detected the presence of the West Nile virus in mosquito samples taken from August 1 to 8 in various municipalities in the Seville province, including Almensilla, Bollullos de la Mitación, Dos Hermanas, Gelves, Los Palacios y Villafranca, and Villamanrique de la Condesa. The virus was also found in Barbate in the Cadiz province. These areas are frequented by British tourists and expatriates, raising further concerns about the virus’s spread.
As of August 21, 2024, human cases of West Nile virus have been reported in eight EU/EEA countries: Austria, Croatia, Hungary, Romania, France, Italy, Greece, and Spain. Additionally, neighboring countries Serbia and Kosovo have also reported cases. The spread of the virus underscores the need for continued vigilance and preventive measures to control its impact.
