About Dengue:

- Dengue is a viral infection caused by the dengue virus (DENV), which is transmitted to humans through the bite of infected mosquitoes.
- The dengue virus is transmitted to humans through the bites of infected female mosquitoes, primarily the Aedes aegypti mosquito.
- Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.
- Most people who get dengue do not have symptoms. For those who do, the most common symptoms are high fever, headache, body aches, nausea and rash.
- In severe cases, dengue can be fatal.
- Dengue is treated through pain management as there is no specific treatment currently.
- There is evidence, however, of the possibility of maternal transmission (i.e. from a pregnant mother to her baby).
- The mosquitoes that spread dengue are active during the day.
