Dengue is transmitted when a person is bitten by a mosquito infected with the dengue virus. The mosquito becomes infected when it bites a person who already has the virus in their bloodstream.
Symptoms:
Symptoms of dengue fever can vary widely and may include:
- High fever
- Severe headache
- Pain behind the eyes
- Joint and muscle pain
- Fatigue
- Nausea and vomiting
- Skin rash, which may appear a few days after the fever starts
- Mild bleeding, such as nosebleeds or gum bleeding
Dengue Severity:
Dengue can range from mild to severe. In some cases, it can progress to a severe form known as dengue hemorrhagic fever (DHF) or dengue shock syndrome (DSS). These conditions can cause:
- Severe abdominal pain
- Persistent vomiting
- Rapid breathing
- Bleeding under the skin, nose, or gums
- Shock and circulatory collapse
Severe dengue can be life-threatening and requires immediate medical attention.
Diagnosis:
Dengue is diagnosed through blood tests that detect the presence of the virus or antibodies against it. Rapid diagnostic tests are available in some areas to quickly identify dengue infection.
Treatment:
There is no specific antiviral treatment for dengue fever. Treatment focuses on relieving symptoms, maintaining hydration, and monitoring for any signs of severe disease. In severe cases, hospitalization may be necessary for close monitoring and supportive care.
Prevention:
Preventing dengue involves controlling mosquito populations and protecting oneself from mosquito bites. Some preventive measures include:
- Eliminating mosquito breeding sites by emptying containers with standing water.
- Using mosquito repellent on exposed skin and clothing.
- Wearing long-sleeved clothing and using bed nets, especially during peak mosquito activity times.
- Using screens on windows and doors to keep mosquitoes out.
Vaccine:
A dengue vaccine is available in some countries, but its use is usually recommended for individuals who have had a prior dengue infection. It’s important to consult with a healthcare professional about the vaccine’s appropriateness for specific individuals.
Dengue is a significant public health concern, especially in tropical and subtropical regions. Early detection, proper medical care, and mosquito control are essential to reducing the impact of this disease. If you suspect you have dengue fever, seek medical attention for proper diagnosis and management.
