Sir: The poliovirus, with all its menacing implications, still haunts children all across Pakistan. Even so many years of relentless efforts to eradicate polio barely managed to keep its devastating effects at bay. However, for the past couple of years, polio struck and struck hard so that multiple cases surfaced. The recently concluded Pakistan Demographic Household Survey (PDHS) paints a very bleak picture regarding the overall national full child vaccination coverage of only 53.8 percent. Many national and international organisations have already expressed their concern that the virus is gaining momentum in the country’s hinterlands and, if left unattended, will soon reach its tipping point and then its spillover will gradually spread to the currently polio-free heartlands of Pakistan. The enormity of the situation demands that the government should double its efforts by introducing high standards of data collection, implementing highly efficient operational strategies to reach previously inaccessible areas and develop strong political commitment to eradicate polio once and for all.
