Students talk on chikungunya and dengue in the assembly. 

What is dengue?
Dengue is a disease caused by any one of four closely related dengue viruses (DENV 1, DENV 2, DENV 3, or DENV 4). The viruses are transmitted to humans by the bite of an infected mosquito. In the western hemisphere, the Aedes aegypti mosquito is the most important transmitter or vector of dengue viruses.
What is chikungunya?
Chikungunya is a relatively rare form of viral fever transmitted to humans by infected mosquitoes. Typically, the Aedes Aegypti mosquito spreads the disease.
