West Nile and dengue alerts spread in Cuba, Mexico, Spain and US

Health authorities in several regions have reported heightened activity of mosquito‑borne viruses. In the United States, the Beaufort County mosquito‑control department confirmed West Nile virus–positive mosquitoes, prompting intensified trapping and public‑health warnings. In Spain, the Andalusian government raised its alert level to cover eleven municipalities after detecting infected mosquitoes, while the towns of La Puebla del Río and Coria were placed on alert following positive traps in urban areas. Local officials in Santa Pola also reported a severe mosquito infestation that has disrupted outdoor activities, leading to increased fumigation efforts.

In Cuba’s Cienfuegos province, health officials continued active surveillance of arboviruses such as dengue and chikungunya, noting small focal points but no widespread transmission. Meanwhile, Mexico’s Tamaulipas state health secretariat recorded 38 confirmed dengue cases, emphasizing ongoing monitoring and community measures to eliminate breeding sites.

Across the affected areas, authorities are reinforcing vector‑control programs, expanding mosquito trapping, issuing public guidance on personal protection, and conducting targeted fumigation to curb mosquito populations and reduce the risk of disease transmission.
