The analysis of initial resistance rates in relation to time shows that the strongest decrease occurred in 1978 and 1981. It must be noted that the only change made to the Tuberculosis Control Programme at the national level was the introduction of short-course treatments as of 1978 in the Metropolitan region and later in the rest of the country, but only partially so. Finally in view of the great epidemiological importance of a regular assessment of resistance rates, it is necessary to investigate with a proved method a representative number of strains from patients not previously treated. Failing these basic requirements, the rates will not reflect the true situation in the country.
