Why dengue is a public health issue globally?
Dengue is recognized as a significant global public health issue due to its widespread distribution, increasing incidence, and the severe economic and health burdens it imposes on affected populations. The disease, caused by the dengue virus transmitted through Aedes mosquitoes, has seen a dramatic rise in cases and geographic spread, affecting an estimated 400 million people annually with over 20,000 deaths reported each year. The World Health Organization has classified dengue as a major international public health concern, highlighting the complexity of its resurgence, which is attributed to factors such as rapid urbanization, international travel, demographic changes, and climatic factors. The expansion of dengue's geographical reach, partly due to climate change and the increasing temperatures and changes in precipitation cycles, poses a threat even to regions previously unaffected, such as Europe. This expansion is compounded by the lack of specific antiviral therapies for treatment, making mosquito vector control the primary strategy for curtailing transmission . Despite efforts, the disease's control is challenged by the mosquito vector's extensive geographic distribution, rapid urbanization, and weak surveillance systems. The economic impact of dengue is profound, with significant costs to public health systems, especially in Latin America and Southeast Asia, where the disease is most prevalent . The development of vaccines has seen progress, yet the first licensed vaccine has shown serostatus-dependent performance, and other candidates are still under trial. The global burden of dengue, estimated at 390 million infections per year, far exceeds previous WHO estimates, underscoring the urgent need for effective control and prevention strategies. In summary, the global challenge of dengue lies in its widespread distribution, increasing incidence, lack of effective treatments, and significant health and economic impacts, necessitating coordinated global efforts in surveillance, vector control, and vaccine development .
