A day after The Indian Express reported the diagnosis of a rare Vaccine Derived Polio Virus (VDPV) in a two-year-old child in Delhi, health minister Satyendar Jain said the government was maintaining due surveillance.
“This is just one very rare case. Immunisation rounds have been carried out in the area, so there is no risk of the virus spreading further,” said Jain.
Government authorities have tested 36 stool samples from the family and others who were in contact with the child. Samples were also taken from seven sewage sites.
The World Health Organisation’s (WHO) Southeast Asian regional office, in a statement Tuesday evening, said “rapid and robust” immunisation cycles were conducted in Delhi and nine bordering districts of Western Uttar Pradesh after the case was reported.
The child was diagnosed with the P2 strain of the virus three weeks ago. WHO said the virus in this case is a very rare strain that occurs in children with immunodeficiency or in populations with low immunity levels.
