Surveillance and registers
THL serves as an expert institute of infectious disease control in Finland. THL monitors the status of infectious diseases and maintains the National Infectious Diseases Register.
Approximately 140,000 cases of infectious diseases are reported to the National Infectious Diseases Register each year. The register data are used to prevent, monitor, control and research infectious diseases.
In addition to the National Infectious Diseases Register, several other systems are used to monitor the disease situation. THL also engages in extensive international cooperation with European expert networks.
