Incidence of traumatic injection neuropathy among children in Pakistan.

We used acute flaccid paralysis surveillance data collected between 1 January 2001 and 31 December 2003 from the Pakistan Polio Eradication Initiative to describe the epidemiological characteristics and disease burden of traumatic injection neuropathy among children aged under 15 years. Of the 5627 acute flaccid paralysis cases reported, 456 were identified as traumatic injection neuropathy by case review. The condition was more common in younger children who were also more likely to have persistent paralysis. We estimate that the annual incidence of traumatic injection neuropathy rate in Pakistan is 7.1 per 1 000 000 in children under 3 years old.
