Municipal workers cut grass in a poor neighbourhood in Asuncion on January 9, 2024, as part of an eradication campaign against the Aedes aegypti mosquito, which spreads the dengue-causing virus. Hospitals in Asuncion are receiving many patients with dengue symptoms. The mosquito-borne disease, endemic to tropical areas, causes high fevers, headaches, nausea, vomiting, muscle pain and, in the most serious cases, bleeding that can lead to death.
