Latin America faces surge in dengue and respiratory infections
Latin American and Caribbean nations are facing significant public health challenges due to rising infectious disease rates. In Peru, dengue cases have surged by approximately 79% in 2026 compared to the previous year, with over 55,900 cases and 67 deaths reported. Health authorities warn that rising temperatures and water storage challenges could drive further increases. Piura, La Libertad, and San Martin are among the hardest-hit regions.
Cuba is also experiencing a dramatic rise in dengue, with 7,133 cases recorded in 2026—roughly 7.4 times higher than historical trends. Meanwhile, El Salvador is managing a dual health burden: a spike in suspected dengue cases and a significant pneumonia outbreak. The country has reported over 7,200 pneumonia cases, resulting in 5,509 hospitalizations and a 3.60% mortality rate, particularly affecting children under nine.
Other regional responses include intensified mosquito control and vaccination efforts in Argentina and Paraguay to mitigate the spread of arboviruses like dengue, Zika, and chikungunya.
