Notification of tuberculosis in the south-west health region of Norway: incidence and trends.
A survey of tuberculosis notification from the south-west health region of Norway showed a decrease from 17.7 cases of tuberculosis per 100,000 population during 1969-1973 to 12.3 cases per 100,000 during 1979-1983. The notification rate linearly increased with age from the age of 20 years on a logarithmic scale. The downward trend in notification was less marked in the last 5-year period compared with the first 5-year period probably due to changes in notification procedures in 1976, an epidemic of tuberculosis in the health region and on oil platforms in the North Sea in 1980 and an increased immigration of people from areas with high incidence of tuberculosis. Tuberculosis of the extrathoracic lymph nodes was during 1979-1983 the most frequent location of non-respiratory tuberculosis.
