Ahmedabad: It's a ticking time bomb. After water contamination triggered a typhoid outbreak in three villages of Bavla taluka of Ahmedabad district, it could well be the turn of 65 more in Sanand taluka alone. "Of the villages we visited in Sanand taluka recently, about 65 have no proper sanitation facilities. The situation is similar to that in the three villages in Bavla taluka. There is great risk of similar outbreak here, as here too proper chlorina-tion of water is not taking place," says a senior officer of Water and Sanitation Man agement Organisation (WASMO). Of the 132 cases of typhoid detected in Bavla, over a 100 have been children. One child is dead. Contaminated (Irinking water, lack of sanitation facilities and government apathy have created a toxic combination that has washed away claims of 'Nirmal Gujarat' and the year of 'Nirogi Balak' (healthy child) of state government. Even now, authorities are working in a knee jerk manner. "We are focusing only on Kalyan-gadh, Kerala and Bhayala villages in Bavla taluka as these were affected. We have told sarpanches of other viUages to be alert. Apart from that, no intervention has been made in other villages in either Bavla or Sanand," said Ahmedabad district development officer (DDO) AJ Shah when asked by TOI on preventive steps being taken. According to WASMO sources, past tests have revealed that water was found to be unfit for consumption in many villages including the ones affected by current outbreak. "We had advised health officials there to start chlorination of water immediately" says an official. On Monday, sarpanch of Kerala village Navghanbhai Patel told TOI that chlorination of water in village started only after March 12. "Before that, we had no idea what chlorination is and what needs to be done," he said. Meanwhile, WASMO officials have collected water samples from 47 villages in Bavla taluka and sent it for testing. This measure has been taken to prevent not just another typhoid outbreak, but other epidemics spread by stagnant water like chikuflgunya and malaria.
