What is dengue fever?
Dengue is a disease endemic to tropical areas that causes high fevers, headaches, nausea, vomiting, muscle pain and, in the most serious cases, bleeding that can lead to death.
The WHO has warned that dengue and other diseases caused by mosquito-borne viruses such as chikungunya, yellow fever and Zika -- are spreading faster and further due to climate change.
