Progress toward poliomyelitis eradication--Pakistan, 1994-1998.

Since the 1988 World Health Assembly resolution to eradicate poliomyelitis by 2000, polio cases reported globally have decreased by approximately 85%. Despite a strong commitment to polio eradication, polio remains endemic in Pakistan. In 1997, Pakistan reported 1147 polio cases, representing widespread poliovirus circulation nationally and constituting 22% of cases reported worldwide. However, surveillance and laboratory data from 1998 indicate that previous widespread poliovirus circulation was geographically localized for the first time. This report describes polio eradication activities in Pakistan, including the impact of routine and supplementary vaccination on polio incidence.
