The number of tuberculosis cases in Finland has decreased. Cases among immigrants have, however, increased, and the disease may not be recognized early enough.
We describe four group exposures to tuberculosis that occurred in Finland, the index patient coming from a country with a high incidence rate of tuberculosis.
Over 900 persons were exposed to tuberculosis. Coordination of the surveys was hampered by the fact that several healthcare operators participated in the study. Three index patients had drug-resistant tuberculosis, one of which was multidrug resistant.
Extensive operations of tracking and prevention could have been avoided, if the symptoms would have been recognized earlier.
