As a key actor both in Finland and internationally, THL will be committed to promoting the health and well-being of the population, preventing disease and social harms, and developing health and
social services. THL pursues and carries out its objectives by means of research, development, information guidance and national services.
The official tasks of the Institute include monitoring of infectious diseases and acting as the statutory statistics authority in the field of health and welfare. THL maintains a strong knowledge
base within the field, steering policy-making through evidence-based information.
In addition to the scientific community, THL seeks to serve the broader society, including professionals in the field of health and social services, as well as decision-makers in central
government and municipalities.
One of its key objectives is to help municipalities develop their health and social services through expert guidance and monitoring. The Institute will help to improve these services in terms of
availability, quality, productivity, efficiency and impact. It will also provide citizens with information for making healthy and welfare-promoting choices and for promoting healthy changes in the
environment. To this end, the Institute co-operates with NGOs and develops new e-health services.
International co-operation has had a significant role in both merging organisations and will continue to be an essential part of THL's activities. The new Institute will maintain and promote close
contacts with European Union bodies, the World Health Organization and a number of scientific and public institutions and agencies as well as affiliate organisations around the world.
