Abstract

We read the Article by Farah Qamar and colleagues about the outbreak of ceftriaxone-resistant Salmonella enterica serotype Typhi in Hyderabad, Pakistan, with great interest. S Typhi was observed as being twice as prevalent in the Qasimabad subdistrict of Hyderabad City (attack rate 15 per 1000 residents) as in the Latifabad subdistrict (seven per 1000 residents), two areas that differ socioeconomically. In most cases, children younger than 15 years were affected. The main reason for the outbreak was the mixing of drinking water and sewage in two subdistricts.
