As a non-profit organization, the DZK has been involved in national TB control for over 125 years, although the tasks have changed over time. Today, we work together using new media to achieve the international goal of eliminating the TB pathogen. We are affiliated to the German Society for Pneumology and work closely with the Public Health Service. In addition to drawing up national treatment and prevention guidelines, we carry out educational work for those affected and interested and conduct health services research in Germany and internationally.
