The three polio cases were found in different districts of the Balochistan.
According to the Balochistan health department, poliovirus has been confirmed in an eight-month-old girl belonging to Union Council Islamyar in Zhob. Samples of the girl were obtained on April 16 and 17.
Other victims, four-and-a-half-year-old and 13-month-old girls, belong to Naseerabad and Jhal Magsi districts.
Three more cases of polio have been found, taking the tally of children infected with poliovirus in the Balochistan this year to ten.
In 2019 when 12 cases were reported from Balochistan, most of the victims belonged to Qila Abdullah, a district of Balochistan located at the Pakistan-Afghanistan border.
Repeated immunisations have protected millions of children from polio, allowing almost all countries in the world to become polio free. Moreover, there are only two countries in the world — Pakistan and Afghanistan — from where polio cases are still reported.
