The World Health Organization (WHO) has reported a staggering 10 million cases of dengue fever in the first half of this year, with over 16,000 severe cases and 3,000 deaths. This represents a threefold increase from the same period in 2023 and highlights the dangers of the pandemic.
One notable case is that of Genesis Polanco Marte, a 9-year-old who was admitted to a hospital in the United States with symptoms of dengue fever. The disease, which was previously common in Southeast Asia but often overlooked in the Western world, has seen a surge in cases due to climate change. The Aedes aegypti mosquito, which carries the virus, is thriving in warmer temperatures, leading to more infections.
The increase in dengue fever cases has overwhelmed hospitals in various countries, with Puerto Rico declaring a public health emergency. Experts warn that the disease could spread to temperate regions, including South America. The lack of specific treatment for dengue fever and the serious complications it can cause make it a significant public health concern.
Climate change is a key factor in the spread of dengue fever, as it creates ideal conditions for the Aedes aegypti mosquito. Hot and stormy weather allows the mosquito to breed more rapidly, increasing the risk of disease transmission. Without effective vaccination strategies, controlling the spread of dengue fever becomes increasingly challenging.
Vaccination against dengue fever remains difficult due to the unique characteristics of the virus, which has multiple serotypes and can cause severe disease. The only licensed vaccine in the US, Dengvaxia, is only effective for individuals who have previously had the disease. Counteracting
