Dengue Fever and Travel: What You Need to Know
Dengue Fever is a mosquito-borne viral disease transmitted primarily through the bite of infected Aedes mosquitoes, which are active during the day. It’s common in tropical and subtropical regions, including parts of Asia, South America, Africa, and the Caribbean. Symptoms can include high fever, severe headache, joint and muscle pain, skin rash, and in some cases, it can lead to severe complications such as Dengue Hemorrhagic Fever or Dengue Shock Syndrome.
There is no specific antiviral treatment for Dengue, making prevention through vaccination and mosquito protection essential—especially for travelers visiting high-risk destinations.
The dengue vaccine (such as QDENGA, where available) is recommended for:
-
Travelers heading to endemic areas for two weeks or longer, especially during peak mosquito season.
-
Individuals with a previous history of Dengue infection who are at risk of severe reinfection.
-
Humanitarian workers or healthcare professionals traveling to regions with ongoing Dengue outbreaks.
-
Families or long-term travelers planning extended stays in high-risk areas.
