Comparative view of relative abundance of dominant bacterial groups in household children at day 0 and as confirmed for household-contact children of cholera patients at day 8, after the delivery of chlorinated water as part of the cholera-hospital-based water, sanitation, and hygiene (WASH) intervention for 7 days (CHoBI7) at the taxonomic level of family. Relative abundance of bacterial families, e.g., Prevotellaceae, Bifidobacteriaceae, Lachnospiraceae, Clostridiaceae, Enterobacteriaceae and Veilloneleceae increased at day 8, while Lactobacillaceae and Ruminococcaceae remained unchanged
