The risk of dengue has increased in recent years due to rapid urbanization, and deficient water management including improper water storage practices in urban, peri-urban and rural areas, leading to proliferation of
mosquito breeding sites. The cases peak after monsoon and it is not uniformly distributed throughout the year.
