Isolation rates for S. Typhi from blood cultures collected in Kibera and Lwak.

*Proportion of pathogens isolated that were S. Typhi by age group.**Proportion of blood cultures done from which S. Typhi was isolated.&Two patients had S. Typhi isolated from blood cultures twice during a seven day period (representing persistent bacteremia); for the purposes of these rate calculations, we excluded one of the blood cultures for each of these patients. We did not have age information for one of the patients.
