An outbreak of pertussis in sarli circle of kurung-kumey district, Arunachal pradesh, India.

ABSTRACT

An outbreak of suspected pertussis occurred in Sarli circle of Kurung-kumey district of Arunachal Pradesh in 2007. We investigated this outbreak to confirm the etiology, estimate the magnitude and identify reasons for its occurrence. Twenty-six deaths were reported from the circle. We identified 72 case-patients meeting the case definition of suspected pertussis. The overall attack rate was 30%. None of the under-five children surveyed had received any vaccine in the past. It is essential to establish facilities for conducting routine immunization in Sarli and organizing special campaign in the area to vaccinate all under-fives with full course of vaccines.
