Giving detail information in this regard Dr Sawant said that the World Health Organization (WHO) is cooperating in India for polio survey as per the international quality parameters.
As a part of this survey, sewage water samples from 45 places in different states including Maharashtra were collected. These samples were examined in five recognised laboratories in the country.
Along with sewage water samples of stools were also regularly examined. Each year around 75,000 stool samples are examined. Because of the vaccination under polio vaccination program the risk factor among the children has been reduced as per the experts’ opinion.
The use of virus infected polio vaccine produced by a certain company has been stopped in the state as per the directions of the central government.
The last polio patient in India was found on January 13, 2011. After that no patient was admitted in the last three years hence the WHO declared India as polio-free country in 2014.
After identification of type 2 polio virus the central government team conducted examinations and found that the virus was present in bOPV viols produced by a certain company.
The Ministry of Health and Family Welfare Ministry (MoHFW) of the central government took the decision to stop the use of this vaccine on September 10.
“In compliance with the central government decision the state government too has stopped the use of this vaccine from September 11. The central government is handling this issue with the help and coordination of WHO with all seriousness and the citizens in the state need not panic,” appealed Maharashtra Health Minister, Dr Deepak Sawant.
The Central Drug Standard Control Organisation (CDSCO) has begun an investigation into the recent polio dose virus case.
The three-member team constituted by the CDSCO will investigate the possible cause of contamination in the poliovirus
Recently, polio vaccines contaminated with a strain of type 2 virus were found in some batches of the oral vaccine manufactured by a Ghaziabad-based company
