New Dengue Fever Vaccine

Dengue fever is caused by the Dengue virus (DENV), which has four strains: DENV-1, DENV-2, DENV-3, and DENV-4. It is transmitted through bites from Aedes mosquitoes.

Symptoms of Dengue Fever

• Sudden high fever (above 38 °C, sometimes reaching 40-41 °C) lasting 2-7 days
• Nausea, vomiting, and loss of appetite
• Red rash, small red spots, or bleeding (nosebleeds, bleeding gums, bloody stool/urine)
• Severe abdominal pain, especially under the right rib cage
• In severe cases: shock syndrome, causing restlessness, cold hands and feet, low blood pressure, and decreased urination
• Liver enlargement and tenderness in some cases
• Recovery usually occurs after 7-10 days, but a red itchy rash may appear on hands and feet before fully healing

High-Risk Groups

• Obese individuals
• People with chronic diseases (diabetes, heart disease, high blood pressure, kidney disease, blood disorders)
• Elderly individuals with weaker immunity
