An outbreak was reported from Ibrahim Khan Village of Manzari union council (UC), Pishin District by medical officer during polio campaign on 15th April 2014. A team was sent to investigate the outbreak and suggest control measures.

Case was defined as "a person of any age, resident of village Ibrahim Khan village with non-vesicular maculopapular rash and fever along with one of the symptoms of cough, coryza and conjunctivitis from April 4th-20th, 2014". Routine immunization (RI) was assessed through recall and immunization cards and BCG scars were checked. Line list was developed and data was analyzed.
Results: Fifty-five cases (attack rate = 11.27%) including 4 deaths (Case Fatality Rates = 7.27%) were found. Mean age of children was 47 months (4-132 Months). Age-group 0-5 years was most affected (n = 48, 87.27%). Along-with maculopapular rash and fever. Other predominant symptoms were: coryza (n = 52, 95%), conjunctivitis (n = 51, 92%) and pneumonia (n = 42, 77%). RI status assessment showed that none of these children had been immunized. About 56.36% of the respondents were unaware about RI, 16.36% mentioned that vaccinator had not visited their homes, 14.54% reported that health facility is far away and 12.72% reported that even if they could get access to a health facility, the vaccines were not available.
