Rapid spread of Dengue fever in Telangana
In the last 10 days, around 1,700 cases of Dengue were reported in multiple districts of Telangana. The state received rains for few days that washed away the mosquito larvae collected in dumps and stagnant water.
Changes in rainfall pattern, rise in humidity level and long spell of warmer temperatures are the main reasons for the recent outspread of Dengue in Telangana. The state is urbanizing at a faster rate after the partition, the construction projects like Amaravati (the capital city being built) have increased. The state Government estimates over 50% of the Telangana population will reside in urban areas by 2023
With unplanned construction projects dumping of discarded objects and stagnation of water have made Telangana conducive for spread of dengue and Chikungunya.
