Why is Dengue Fever in Costa Rica getting worse?

Dengue fever in Costa Rica is worsening due to several factors, including increased urbanization that creates breeding grounds for mosquitoes, particularly Aedes aegypti, which transmit the virus. Climate change also plays a role by extending the mosquito breeding season and increasing their range. Additionally, public health challenges such as inadequate vector control measures and a lack of community awareness contribute to the rising incidence of the disease. Efforts to manage and mitigate outbreaks are further complicated by resource constraints and the need for improved surveillance systems.
