Spanish health authorities are sounding the alarm after a surge in West Nile virus infections, with 13 new cases confirmed this week. The virus is particularly prevalent in the Sevilla and Huelva regions, causing concern among public health officials. Six cases were reported in Dos Hermanas, a town near Sevilla, and three in Coria del Rio. Additional cases were confirmed in La Puebla del Rio, Mairena del Aljarafe, Alcala de Guadaira, and Campofrio in Huelva province.
West Nile virus can manifest in a range of ways. About 20% of infected individuals experience mild symptoms like 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. Individuals over 50 and those with pre-existing health conditions like diabetes, high blood pressure, or cancer are at higher risk of experiencing severe symptoms.
The European Centre for Disease Prevention and Control (ECDC) highlighted the severity of 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, highlighting its growing reach. Countries like Italy, Greece, Romania, Hungary, and Spain were identified as hotspots for West Nile virus.
The rise in cases is attributed to increased mosquito activity, which serves as the primary vector for virus transmission. The Ministry of Health has advised the public to take preventive measures against mosquito bites, especially during dawn and dusk when mosquitoes are most active. 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 virus in mosquito samples collected 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 spread of the virus.
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.
