Dengue Fever

Dengue fever is an acute, mosquito-borne viral illness caused by four distinct, but closely related, dengue viruses. It is an important public health concern in tropical and subtropical regions of the world, with an estimated 390 million infections per year across the globe. The virus is spread by the bite of an infected Aedes aegypti mosquito. Symptoms of dengue fever include sudden onset of fever, severe headache, joint and muscle pain, nausea, vomiting, swollen glands, and skin rash. Treatment of dengue fever involves rest and supportive care, including taking acetaminophen for pain and fever reduction. Severe cases of dengue fever may require hospitalization for rehydration, monitoring for complications, and supportive care. Prevention of dengue fever primarily involves personal protection measures against mosquito bites and vector control.
