India has recorded its first case of polio infection this year. The victim of the crippling disease is an 18-month-old girl from West Bengal’s Howrah district. She tested for polio after the onset of paralysis on June 13. The girl has been infected with the dangerous type-1 virus. The P1 strain of polio causes large outbreaks and paralyses one out of every 200 children infected. The Union health ministry was informed that the child was never immunized against polio before the virus infected her. She had not received any dose of the oral polio vaccine (OPV) either in the nationwide polio campaigns or under routine immunization.
