What Causes Dengue Fever?

Dengue fever is caused by a virus known as the dengue virus. This virus is primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. These mosquitoes are commonly found in tropical and subtropical regions around the world.

Transmission of Dengue Virus

When an Aedes mosquito bites a person infected with the dengue virus, it becomes a carrier of the virus. The mosquito can then transmit the virus to another person through its bite. This cycle continues, leading to the spread of dengue fever.

Symptoms of Dengue Fever

The symptoms of dengue fever typically appear 4-10 days after being bitten by an infected mosquito. These symptoms can range from mild to severe and may include high fever, severe headache, joint and muscle pain, rash, and in severe cases, bleeding.

Treatment and Prevention

There is no specific treatment for dengue fever, and management usually involves supportive care to relieve symptoms. Prevention is key in controlling the spread of the disease. This includes reducing mosquito breeding sites, using mosquito repellents, wearing protective clothing, and seeking medical attention if symptoms develop.

In conclusion, dengue fever is caused by the dengue virus, which is transmitted to humans through the bite of infected Aedes mosquitoes. Understanding the transmission and symptoms of dengue fever is crucial in preventing and managing this potentially serious illness.
