Evidence-backed informationEN 5/7 applicable sections · ZH 5/7 applicable sectionsUpdated Sep 3, 2026

Dengue is a mosquito-borne viral infection widespread in warm tropical and subtropical regions, caused by any of four antigenically distinct dengue virus serotypes transmitted principally by Aedes mosquitoes. The disease produces a spectrum of illness ranging from asymptomatic or mild febrile episodes to severe hemorrhagic complications and fatalities. In recent decades dengue has expanded geographically, with intensifying outbreaks; WHO graded the situation as a Grade 3 emergency in 2023 amid rising transmission in multiple countries. No antiviral therapy exists, and prevention relies on vector control and, where available, vaccination, making sustained surveillance and integrated programmatic responses central to containment efforts.[1][2][3]

Definition

Dengue is a vector-borne viral disease caused by the positive-stranded RNA flavivirus dengue virus (DENV), which comprises four antigenically distinct serotypes (DENV-1 through DENV-4). It is the most rapidly spreading mosquito-transmitted viral disease and is endemic across more than 100 tropical and subtropical countries, where Aedes mosquitoes sustain transmission cycles.[1][2][3]

Clinical features

Clinical manifestations form a broad continuum from unnoticeable infection through classic dengue fever to severe dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). After an incubation of roughly 4–10 days, symptomatic patients typically present with flu-like illness that may include high fever, severe headache, retro-orbital pain, myalgia, arthralgia, nausea, and rash. As disease advances, patients may develop respiratory distress, mucosal bleeding, plasma leakage with a rapid drop in blood pressure, thrombocytopenia, and leucopenia, and in the most critical presentations, shock and death.[1][2][3]

Epidemiology

Dengue is endemic throughout tropical and subtropical regions and is now the most important mosquito-borne tropical infectious disease after malaria in its global public-health impact. Recent estimates place annual cases at approximately 400 million worldwide, with roughly 22,000 deaths, and historic burden estimates have cited up to 100 million cases of dengue fever and 500,000 cases of DHF per year. Transmission exhibits seasonal patterns, typically peaking during and immediately after rainy seasons, and is amplified by high mosquito densities, co-circulation of multiple serotypes (hyperendemicity), rising urban temperatures, heat waves, and gaps in sustained vector-control programmes. WHO escalated dengue to a Grade 3 emergency in 2023 in response to expanding outbreaks across multiple countries.[1][4][3]

Transmission

Dengue is principally transmitted to humans through the bites of infected female Aedes mosquitoes. The four DENV serotypes circulate in tropical and subtropical settings, and many infected individuals remain asymptomatic yet still contribute to onward transmission through mosquito vectors. Epidemic intensity is shaped by mosquito abundance, environmental conditions such as precipitation, humidity, and warm temperatures that shorten viral incubation and alter vector feeding behaviour.[1][2][3]

Prevention

Because no universally effective antiviral therapy exists, prevention depends on vector control, sustained surveillance, and integrated public-health programmes that reduce Aedes mosquito populations and limit human–vector contact. A first licensed tetravalent dengue vaccine (CYD Denvaxia) has been introduced in some settings but is not approved everywhere, and additional vaccine candidates remain under development. Strengthening programmatic approaches, addressing unplanned urbanisation, and maintaining adequate staffing for surveillance and control are highlighted as core elements of prevention strategy.[1][2][3][5]
