"The boy is stable and on ventilator, being treated at the B J Wadia hospital at Parel (central Mumbai)," director of Health Services Dr Satish Pawar told PTI here.
The child, Arsh Singh, was suspected to be suffering from Guillain-Barre Syndrome(which, like polio, leads to paralysis) and his stool reports confirmed the presence of VDPV, Dr Pawar said. "We are now testing other children in his home and locality," he added.
The child had been administered the oral polio vaccine at least five times.
This is the second case of VDPV in Maharashtra and fourth in the country this year, the official said. In June, a 10-month old boy from Beed in the state, who had contracted VDPV, died at a hospital.
