Explore the global impact of dengue fever, which can affect (when people get infected) over half of the world's population. While the majority of individuals will be asymptomatic or have only mild symptoms, some occasionally develop life-threatening symptoms leading to a significant number of infections, hospitalizations, and deaths annually. Discover the challenges in diagnosis, the increasing prevalence due to factors like air travel and urbanization, and the imperative for comprehensive interventions including mosquito control, public education, and vaccine development to mitigate its potential burden on health systems during outbreaks.

Sophie contracted dengue fever when she was 15 years old while visiting the Bahamas. She was informally diagnosed with dengue by a doctor based on her symptoms and the high likelihood as there was a local epidemic at the time. Sophie became very ill (as is the case with about 5% of people who have symptomatic dengue)1 and her experience has changed the way she now travels. To ease her concerns about getting dengue again, she is now more aware of, and takes, protective measures when travelling to an area of risk.

Natasha reflects on becoming ill with dengue and thinks she may have been infected when visiting a swimming pool at night – a place at which she often spends time with her friends. Natasha received treatment in hospital where she was given saline through an IV. Although only about 1 in 4 dengue cases are symptomatic1, Natasha is now worried about getting dengue again from places where she “hangs around a lot” with her friends, such as the swimming pool. Natasha’s advice to people living in dengue endemic countries is to “always keep in mind you could get dengue at any time”.
