What Is Dengue Fever?

Dengue fever is a viral infection caused by the dengue virus, which is transmitted to humans through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes. Symptoms include high fever, severe headaches, muscle and joint pain, rash, and in severe cases, life-threatening complications such as dengue haemorrhagic fever or dengue shock syndrome.

Who Is At Risk Of Dengue Fever?

Dengue fever can affect anyone living in or traveling to tropical and subtropical regions where Aedes mosquitoes thrive. Urban and semi-urban areas with stagnant water sources are particularly high-risk zones. Individuals who have previously had dengue are at higher risk of severe disease if infected again.

How Is Dengue Fever Spread?

Unlike respiratory diseases, dengue fever is not spread from person to person. Instead, it is transmitted through the bite of an infected mosquito. These mosquitoes are most active during the day, particularly early morning and late afternoon.

Where Is Dengue Fever Common?

Dengue fever is endemic in many tropical and subtropical regions, including Southeast Asia, the Pacific Islands, the Caribbean, Central and South America, and parts of Africa. Travelers to these areas are advised to take preventive measures.

The Importance Of The Dengue Vaccine

Vaccination is an important tool for reducing the risk of dengue fever, especially for those living in or traveling to high-risk areas. In addition to vaccination, protective measures such as using mosquito repellents, wearing long-sleeved clothing, and avoiding areas with standing water are crucial.
