Figures
regarding incidence, morbidity and mortality of TB are expressed per 100,000 inhabitants
of the defined population in a given year, and represent a situation at a given point in
time. Used serially, the figures reflect trends. Mortality rates from TB have fallen slowly from ca. 1810 in the 18th century up to 1914, the fall increased somewhat between 1920 – 1940, and increased sharply after 1945. The highest mortality occurred in Alaska, N. Canada and Greenland (ca. 750 in 1950), at present < 5 / 100,000. The role of BCG vaccination has almost disappeared and become replaced by the important role of the tuberculin index, which reflects the TB situation in a country. |
