[Historical evolution of Marianao municipality: setting in which the fight against tuberculosis developed]. / Evolución histórica del m unicipio Marianao: contexto en que se desarrola la lucha antituberculosa.

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.

[Meningococcal disease in the City of Havana before and after vaccination]. / Comportamiento de la enfermedad meningocócica en el territorio de Ciudad de La Habana antes y después de la vacunación.

The development of risk before and after vaccination in the City of Havana province was described. Data were collected from epidemiological surveys of all cases under 5 years diagnosed with meningococcal disease during pre-vaccination period (1983-1984) and post-vaccination period (989,1990 and 1998). They were processed by using the Geographic Information System Mapinfo 4.1. During 1983 and 1984 when there was no vaccinal intervention, high incidence rates in all age groups were observed in most of the municipalities of the province. However, in 1989, the vaccination coverage was extensive and from that moment on, the incidence rates decreased and the number of meningitis-free municipalities grew. A decrease in frequency of sick children, non-vaccinated children and a very small number of children who were not vaccinated as they should have been was observed. The benefits of an homogeneous intervention at territorial level in the province were proved.
