Hyderabad, Sept. 21: Due to continuing rains in the state, viral fever and cholera cases are on rise in several areas including the state capital. Poor sanitation and contaminated water supply are cited as main reasons by the health experts for the spread of the water-borne diseases. Incidentally, the majority of the cholera cases have been reported from the twin cities and the neighbouring Ranga Reddy district. Director of health, Dr D. Ramesh Chandra, said, "Usually, between the second half of June and December, different types of air-borne, water-borne and vector-borne diseases spread rapidly." Dr Chandra revealed that around 65 to 70 confirmed cases of cholera have reported in the state so far this year which is more than the number of cases reported during the same period last year. However, other diseases like dengue and diarrhoea are showing a downward trend. According to the statistics with health officials, the number of confirmed dengue cases this year is around 85. Dr Chandra added, "We are taking all necessary steps to improve the health conditions. In medical camps we are distributing oral rehydration salts." The department is also asking people to drink boiled water. Even measures to check mosquito breeding have been taken. But ground situation is apparently different from what the officials claim. Mr Abharamurthy, a resident of Madhavapuri in Kapra says, "Viral fevers are rampant. In our locality, each household has one or two patients. After the recent floods, pools of stagnant water have become breeding grounds from mosquitoes." He said that no sanitation measures have been taken up by the health authorities. Fever hospital, Osmania and Gandhi hospitals too are receiving large number of viral fever cases.
