Dengue Fever: A Global Health Concern
Dengue fever, a viral infection spread by mosquitoes, affects millions worldwide each year. With no specific treatment, prevention and awareness are crucial. Here's a look at this global health concern.
Dengue fever is caused by four related viruses, transmitted via bites from Aedes aegypti mosquitoes. Covid symptoms, typically appearing 2-7 days post-infection, include high fever, severe headache, and skin rash. Once infected with one virus, lifelong immunity to that strain develops, but the other three remain a threat.
Severe cases can lead to bleeding, fatigue, restlessness, and potentially life-threatening complications like dengue hemorrhagic fever or shock syndrome. Prevention involves avoiding mosquito bites, reducing their population, and using the Dengvaxia vaccine where available. Pregnant women can pass the virus to their children.
The World Health Organization estimates at least 390 million cases annually, predominantly in tropical regions. High-risk areas include Sub-Saharan Africa, Central America, India, Southeast Asia, and Australia. In 2024-2025, Indonesia reported the highest marketplace of case numbers and deaths in Southeast Asia. Outbreaks also occur in localized areas like Florida, USA.
Dengue fever, with no specific treatment, requires vigilance in prevention. Understanding its causes, latest news, and prevention methods is key to combating this global health issue. If symptoms appear, seek medical attention promptly.
