Efficacy of disinfectants on control and clinical bacteria strains at a zonal referral hospital in Mwanza, Tanzania: a cross sectional hospital-based study.

Contaminated-hospital surfaces are an important source of pathogenic bacteria causing health-care associated infection (HCAIs). Monitoring the performance of disinfectants that are routinely used to clean hospital surfaces is critical for prevention and control of HCAIs. Nevertheless, the evaluation of the performance of disinfectants and their efficacy are not routinely practiced in most resource-limited countries.
