PUERTO VALLARTA, JALISCO. – Efforts to prevent the spread of dengue in Puerto Vallarta continue, as city authorities work to eliminate potential breeding grounds for the Aedes aegypti mosquito, the carrier of the dengue virus. According to the Jalisco Ministry of Health, local cleanup programs last year removed 1,886 tons of junk from homes and public spaces, materials that often become mosquito breeding grounds. Despite these efforts, dengue claimed three lives in Puerto Vallarta in the same period and infected 827 others.
