Dengue Fever is a mosquito-borne viral infection caused by the dengue virus and transmitted primarily through the bite of infected Aedes aegypti mosquitoes. These mosquitoes are most active during the early morning and before sunset and commonly breed in clean, stagnant water found in containers, flower pots, old tires, water tanks, and other uncovered water sources. Dengue is a major public health concern in many tropical and subtropical countries, including Pakistan, where outbreaks are more common during the rainy and post-monsoon seasons.
After being bitten by an infected mosquito, symptoms usually appear within 4 to 10 days. The illness can range from mild to severe. Most people recover within one to two weeks with proper rest and supportive care. However, some patients may develop Severe Dengue (Dengue Hemorrhagic Fever or Dengue Shock Syndrome), a life-threatening condition that can cause internal bleeding, organ damage, and dangerously low blood pressure. Immediate medical treatment is essential in such cases.
Currently, there is no specific antiviral medicine that cures dengue. Treatment mainly focuses on relieving symptoms, preventing dehydration, and closely monitoring the patient's condition. Drinking plenty of fluids, getting adequate rest, and using medications such as paracetamol to reduce fever are commonly recommended. Medicines like aspirin and ibuprofen should be avoided because they increase the risk of bleeding.
Early diagnosis and proper medical supervision are extremely important to reduce complications. Blood tests are often performed to confirm dengue infection and monitor platelet counts and other blood parameters. Community awareness, mosquito control programs, and personal protective measures play a vital role in preventing the spread of dengue. Eliminating mosquito breeding sites, using insect repellents, wearing protective clothing, and maintaining clean surroundings are among the most effective ways to reduce the risk of infection. With timely treatment and proper care, the majority of patients recover completely without long-term health problems.
Dengue Fever is caused by the dengue virus, which is transmitted through the bite of an infected Aedes mosquito. The virus is not spread directly from person to person through casual contact. Mosquitoes become infected after biting a person who already has dengue and then spread the virus to others through subsequent bites. Factors that increase the risk of dengue include living in or traveling to tropical regions, poor sanitation, stagnant water around homes, rainy weather, lack of mosquito control, and previous dengue infection, which may increase the risk of developing severe dengue during future infections.
The best way to prevent dengue is to avoid mosquito bites and eliminate mosquito breeding sites. Empty or cover containers that collect stagnant water, clean water tanks regularly, and dispose of unused tires, cans, and other items that can hold water. Use mosquito repellents, wear long-sleeved clothing, install window screens, and sleep under mosquito nets when necessary. Community mosquito control programs, public awareness campaigns, and keeping the environment clean are essential for reducing the spread of dengue. During outbreaks, individuals should take extra precautions and seek medical attention immediately if they develop symptoms after being bitten by mosquitoes.
