Puerto Rico has declared a public health emergency this week due to a significant increase in cases of potentially deadly dengue fever, a mosquito-borne infection, across the territory. The Department of Health recorded 549 cases so far this year, marking a 140 percent increase compared to the same period last year. The outbreak has exceeded historical records, according to Health Secretary Carlos Mellado López.
This surge in dengue cases is part of a global trend, with countries like Bangladesh, Sri Lanka, and many parts of Central and South America also facing large outbreaks. Climate change and rising temperatures are contributing to the spread of mosquito-borne illnesses like dengue. The environment has become more conducive to mosquitoes, allowing them to move into new areas and elevations.
Factors like El Niño, decaying infrastructure, and urban development are also contributing to the rise in dengue cases. In Puerto Rico, over 340 people have been hospitalized with severe symptoms, mostly in the capital, San Juan. While the disease cannot be passed directly between people, controlling mosquito populations is crucial in preventing further transmission.
There is no one-size-fits-all solution to combating dengue outbreaks, and governments are implementing various strategies to control the spread. In the United States, the risk of dengue is still primarily tied to travel, but preventative measures are advised for travelers to at-risk regions. Ultimately, reducing exposure to mosquitoes through indoor protection and insect repellents is key to minimizing the impact of dengue outbreaks.
