Sir: Despite praiseworthy efforts by the concerned authority, another polio case was reported in Union Council 1 of Landhi, Karachi. With this new case, the total number of polio cases reached to 57 in the current year. Still, the concerned authority needs to do more to eradicate the virus from the country and for this the public should play their due rules and cooperate with the polio eradication team to make the country polio-free.
