At least six more persons of Vareli village in Palsana tehsil have been admitted to hospitals, said District Development Officer and Collector (in-charge) K Rajesh, adding that a team of medical officers was camping at the village and had set up a control room to provide medical assistance to the villagers.
"The death toll has climbed to 13. Six persons are undergoing treatment, four at a government hospital and two at a private hospital. The exact cause of the deaths is yet to be ascertained, though methanol poisoning is not ruled out," he said.
Surat Collector Mahendra Patel had said yesterday that nine persons had died in the last three days at Vareli and primary medical reports suggested that they died due to consumption of some kind of a poisonous substance like methyl alcohol (which is often found in spurious liquor).
Police said a massive search operation was launched in the area to trace the dens selling hooch. At least six police inspectors, posted in the Surat rural area, were transferred in the aftermath of the incident, they added.
Officials did not rule out the possibility of an outbreak of some viral disease as a cause of the deaths. Rajesh said samples had also been sent to the National Institute of Virology in Pune to explore the possibility.
