Household Transmission Dynamics of Multidrug Resistant Enterobacterales

The HOME study will prospectively follow a cohort of Multi-Drug Resistant Enterobacterales (MDR-E) carriers after hospital discharge, and their related household members over a 3-month period. The main objective is to estimate the rate of confirmed transmissions of MDR-E from the index cases to related household members, and identify predictors associated with transmission. Transmission will be confirmed by comparing genomic analysis of the MDR-E strains isolated both in the index patient and his/her household members, based on the number of Single nucleotide polymorphisms (SNPs) differences between nearby genomes by Variant Calling. Multifactorial processes involved in MDR-E transmission in households will be explored with stochastic individual-based modelling. The parameterized model will be used to simulate and assess different strategies of control of MDR-E emergence and transmission to households. The impact of modifying patterns of human-contacts, promote hygiene and control barriers (decontamination of objects or surfaces, variations in antibiotic use, reinforcement of hand hygiene) will be assessed.
