Amid a constant rise in dengue cases, 11 states are reporting serotype-2 dengue cases, which is a more dangerous type of dengue. The centre has asked these 11 states to take necessary steps for early detection of cases and informs that Serotype-2 dengue is associated with more complications than other forms. Dengue is a mosquito-borne viral disease that is transmitted by female mosquitoes mainly, Aedes aegypti. Every year, India sees a surge in dengue cases during monsoon. Humid temperature and stagnant water promote the breeding of mosquitoes in the monsoon.
