Understanding Dengue Fever
Causes and Transmission
Dengue fever is caused by the dengue virus, which has four distinct serotypes (DENV-1, DENV-2, DENV-3, and DENV-4). The virus is transmitted to humans through the bite of infected female Aedes mosquitoes.
Public awareness about dengue fever, prevention, and treatment is essential for disease control. These mosquitoes typically breed in stagnant water found in containers like pots, tires, and tanks. The transmission cycle begins when a mosquito bites an infected person, becomes infected itself, and subsequently bites another individual.
Symptoms and Diagnosis
The incubation period of dengue fever ranges from 4 to 10 days after the bite of an infected mosquito. Symptoms include sudden high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding (such as nose or gum bleeding).
Research on dengue fever prevention and treatment is ongoing to develop new strategies. In severe cases, symptoms can progress to DHF or DSS, characterized by plasma leakage, fluid accumulation, severe bleeding, or organ impairment.
Risk Factors
Certain factors increase the risk of severe dengue, including previous infection with a different dengue serotype, age (younger children and the elderly), and underlying health conditions. A holistic approach is required for sustainable dengue fever prevention and treatment.
Geographic and environmental factors also play a role, as dengue is more prevalent in densely populated urban areas in tropical and subtropical climates.
Prevention Measures
Personal Protection
Preventing mosquito bites is the first line of defense against dengue fever. Individuals are advised to use mosquito repellents containing DEET, Picaridin, or oil of lemon eucalyptus. A combination of prevention and treatment measures is necessary to control dengue fever.
