Shigella and Enterotoxigenic Escherichia coli Have Replaced Rotavirus as Main Causes of Childhood Diarrhea in Rwanda After 10 Years of Rotavirus Vaccination.

ABSTRACT: The causes of diarrhea after 10 years of rotavirus vaccination in Rwanda were investigated with real-time polymerase chain reaction in 496 children with diarrhea and 298 without. Rotavirus was detected in 11% of children with diarrhea (odds ratio, 2.48; P = .002). Comparison of population attributable fractions (PAFs) shows that Shigella (PAF, 11%) and enterotoxigenic Escherichia coli producing labile toxin (PAF, 12%) have replaced rotavirus as the main causative agents. The PAF for rotavirus had declined from 41% prevaccination to 6.5% postvaccination, indicating that rotavirus has become one among several similarly important causes of childhood diarrhea in Rwanda. A rotavirus genotype shift to G3P[8] points at the importance of continued genotype surveillance.
