When a National TB Programme (NTP) functions well, indicators can be obtained from the local authorities and NTP.
The WHO tuberculosis country profiles also provide an estimation of TB indicators by individual country1 .
Box 1.1 - Most common indicators
Annual incidence rate of TB cases(a)
Annual incidence rate of smear-positive PTB cases(a)
Prevalence of smear-positive PTB cases over a given period of time, usually one year(b)
Proportion of multidrug- and rifampicin-resistant TB cases among TB cases over a given period of time(c)
Proportion of extensively drug-resistant TB cases among TB cases over a given period of time(c)
Proportion of HIV-infected patients among new TB cases over a given period of time(c)
(a) The rate is expressed as the number of new TB cases (or new smear-positive PTB cases) per 100,000 population.
(b) Prevalence is expressed as the number of smear-positive PTB cases per 100,000 population. It includes new and pre-existing cases. Prevalence represents approximately double the incidence rate.
(c) Proportion is expressed in %.
