Circulating Vaccine-derived poliovirus (cVDPV) is associated with 4 cases of Acute Flaccid Paralysis (AFP) caused by Oral Polio Vaccine (OPV).

QUETTA: 
The Prime Minister’s polio cell, the World Health Organisation (WHO), and the United Nations Children’s Fund (UNICEF) confirmed that a newly-found strain of the polio virus is the result of persistently low Routine Immunisation (RI) coverage in the Pishin and Qilla Abdullah districts of Balochistan.

The virus has been confirmed in four children in Qilla Abdullah and one in Pishin, according to a joint statement issued on Thursday.

The release stated that ‘cVDPV (Type 2)’ cases are due to poor routine immunisation coverage that may cause type 2 poliovirus to mutate and attain a form that can cause paralysis after passing through multiple children in environments with substandard sanitation.
