Although the number of tuberculosis patients shows an increase worldwide, the number of new infections in all Western industrialized countries has been steadily declining over recent years.

In Germany, 11,000 new cases of Tuberculosis were statistically recorded annually in the last decade, which corresponds to an incidence of 13 per 100,000 inhabitants.

One third of the patients affected belong to marginalised social groups, e.g. foreigners, homeless people, people dependent on drugs or prisoners. The occurrence of Tuberculosis in Western Europe is similar.

The highest incidence of Tuberculosis has been recorded in Africa and South East Asia. 95 % of new infections can be found in populations living below the poverty line.
