PULMONARY TUBERCULOSIS.

Although the total notifications of this disease remain the same as in the previous year, there was a very appreciable decrease in the number of presumed locally contracted cases, viz. a 50 per cent, decrease in Khartoum and 30 per cent, in Omdurman. Cases contracted outside the province boundaries, but coming to one or other of the hospitals for treatment show an increase of approx¬ imately 75 per cent.

During the last 17 years notifications of locally contracted pulmonary tub¬ erculosis have shewn a steady increase from 9 in 1912 to a maximum of 52 in 1926. These figures may at first suggest that this insidious disease is gaining ground among the people of this province.

Since the population have been exposed to this disease by contact with the outside world for probably more than 40 years, one would have expected a higher incidence among such susceptible people ; an explanation of the apparent increase is however to be found in the increased population together with greater facilities for hospital and general medical treatment. With the steady economic development of the country, the individual is enabled to feed and clothe himself and his family better and in many instances to improve his housing conditions.

The following table shows the result of investigation at the end of the year of all notified coses. The case mortality of all cases was 50 per cent, and of locally contracted cases was 61.9 per cent.
