A research on the fight against tuberculosis in Marianao municipality was made. In Cuba, this campaign since its beginning was in the hands of private entities with limited resources that were inscrupulously managed. The Marianao municipality, established in 1878, had municipal administrations that implemented negative policies for the people's interests and propitiated the spreading of tuberculosis due to the terrible working and living conditions of the population. Since the triumph of the Revolution, in 1959, it was established in Cuba a systematic fight against tuberculosis with the introduction of the National Control Program that acts in a decentralized way from the municipal level. In this municipality, the incidence of tuberculosis has historically been a health problem, although at present there is a trend towards the decrease of this disease and it occupies the 13th place among the 15 municipalites of the province of Havana City.
