Health authorities and experts in Latin America are focusing on mosquito control and prevention strategies to combat dengue, chikungunya, and zika viruses. In Nicaragua and Argentina, officials have emphasized monitoring mosquito vectors like Aedes aegypti and Aedes albopictus, urging the elimination of standing water to disrupt breeding cycles.

During a forum in Colombia, health experts warned that a recent decline in case numbers should not lead to a false sense of security. They noted that while regional cases decreased in 2025, factors such as urbanization, climate phenomena like El Niño, and human mobility maintain high transmission risks. This follows a period of unprecedented impact, including a season in Argentina that saw over 580,000 confirmed cases and 419 deaths.
