Dengue and chikungunya are mosquito-borne viral diseases with similar symptoms but important differences. Learn how they compare in symptoms, complications, diagnosis, treatment and prevention, supported by reliable public health data.
Infectious diseases are not rising uniformly around the world. Explore seven major diseases, including dengue, malaria, measles, cholera, chikungunya, Oropouche, and yellow fever,through recent case numbers, geographic hotspots, and evidence of resurgence or expansion.
Dengue has reached record levels in recent years, but the global trend is not uniform. This data-driven analysis examines where dengue cases are rising and falling, the factors driving recent outbreaks, and what modelling suggests about the future of dengue.
Dengue is more than a mosquito-borne disease—it carries a major economic burden. Explore the costs of dengue worldwide, including healthcare, lost productivity, household expenses and public-health spending, with data from Asia, Latin America and other regions.
Dengue and malaria can both cause fever, but they are very different diseases. Explore 15 key differences in their causes, symptoms, transmission, diagnosis, treatment and prevention.
Dengue has evolved from a poorly understood tropical fever into a major global health threat. Explore its history from early descriptions and the 1780 Philadelphia outbreak to the discovery of dengue virus serotypes, the emergence of dengue haemorrhagic fever, and the record number of cases reported in 2024.
What is Dengue? Dengue is a globally significant mosquito-borne viral infection caused by four closely related serotypes (DENV-1 to DENV-4).
