Dengue Fever is a viral illness spread by the bite of infected Aedes mosquitoes, particularly Aedes aegypti. Symptoms usually appear 4 to 10 days after the bite and can include high fever, severe headaches, joint and muscle pain, and rash. In some cases, it can develop into a more severe form known as Dengue Hemorrhagic Fever, which can be life-threatening. Preventing Dengue Fever involves reducing mosquito populations and avoiding bites. This can be done by using insect repellent, wearing long sleeves, and eliminating standing water where mosquitoes breed. Awareness and community efforts are essential in controlling outbreaks and protecting public health.
