Dengue Fever Warning
Severe Outbreak – May Lead to Sudden Death
Causes of Dengue Fever
Dengue fever is a mosquito-borne viral disease transmitted primarily by female Aedes mosquitoes. These mosquitoes can spread the disease throughout the year, especially during the rainy season when mosquito populations increase.
After a mosquito bites an infected person, the virus incubates inside the mosquito for approximately 8–10 days before it can be transmitted to another person. Once infected, a person may carry the virus for about 2–7 days before symptoms appear. During this period, the infected individual can serve as a source of infection for other mosquitoes, which can then spread the disease to more people.
Although Aedes mosquitoes are the primary carriers of dengue virus, mosquito breeding sites are commonly found in stagnant water containers around homes and communities. Eliminating these breeding grounds is essential for disease prevention.
When Should You Suspect Dengue Fever?
The symptoms of dengue fever are often non-specific and may resemble other illnesses.
In children, symptoms may be limited to fever and a rash. In adults, symptoms are often more severe and may include:
- High fever lasting 2–7 days
- Loss of appetite
- Facial flushing
- Severe headache
- Pain behind the eyes
- Muscle and joint pain
- Nausea and vomiting
- Abdominal pain
Additional warning signs may include:
- Red spots or small bleeding points on the skin
- Nosebleeds
- Bleeding gums
- Black stools caused by gastrointestinal bleeding
Severe dengue can lead to shock and life-threatening complications. Seek immediate medical attention if the patient develops:
- Cold hands and feet
- Excessive sweating
- Extreme weakness
- Loss of consciousness
Prompt diagnosis and treatment can significantly reduce the risk of severe complications and death.
