[The present tuberculosis situation in developing countries].

Analysis of the tuberculosis situation and its dynamics in developing countries is given. The data on tuberculosis incidence in developing countries are inadequate and are probably by far higher than the figures reported. The rist of tuberculosis infection amounts up to 3% per year. In future it is supposed that the number of tuberculosis patients will rather increase than decrease. Effective tuberculosis control measures would be possible and are necessary. If nothing is done immediately, the cost of such measures will increase and human suffering will become more severe.
