Concept –

Dengue is transmitted by several species of mosquitoes within the genus Aedes.
Symptoms include fever, headache, muscle, and joint pain, and a characteristic skin rash that is similar to measles.
There are four types of dengue strains, and type II and IV are considered to be more severe and normally require hospitalisation. According to experts, the aedes mosquito breeds in clean stagnant water.
Cases of malaria, chikungunya and viral fever are also rampant during rainy season.
Dengue and chikungunya are caused by the bite of Aedesagypti mosquito, which breeds in clear water.
The Anopheles mosquito, which causes malaria, can breed in both fresh and muddy water.
