After some years, the introduction of antibiotics and better living conditions helped to curb the tuberculosis epidemic in Norway. At the same time, it was discovered that other disease groups, such as heart, vascular and lung disease, also led to disability. This resulted in THO changing its name to the National Association for Heart and Lung Disease (LHL) in 1961.

In solidarity with people affected by tuberculosis in other countries, LHL resumed the fight against tuberculosis in the 1980s in Russia and on the African continent. In 2013, LHL International was founded and became the organization it is today. We strive to use the experience of THO to mobilize communities and people affected by tuberculosis to fight for social change and improve the lives of people with tuberculosis the same way they did.
