Drug resistance surveillance

Two main mechanisms of surveillance are able to collect data on drug resistance representative of a geographically-defined population to allow for comparison across settings and within settings over time: surveillance based on routine DST of all TB patients and periodic surveys of sampled TB patients.


The mechanism of surveillance that is more strongly able to fulfill systematic and ongoing requisites is a system that continuously collects DST data, however capacity is currently not available in most of the PICTs for routine DST of all TB cases and surveys need to be conducted to measure drug resistance among a sample of patients representative of the population under study.
