Notifications of this disease continue to show a slight increase, 6 more cases were notified than during the preceding 12 months ; this increase is due to the fact that no less than 7 positive contacts or carriers were discovered during the course of our investigations into cases.

Special attention has been paid during the year to the examination of the stools and urine of all contacts, since it has not been possible to incriminate milk or water supplies. In one instance the Government Bacteriologist isolated a typhoid like organism from well water in Khartoum North, the bacillus was typical in certain re-actions, three cases of typhoid fever occurred amongst . persons using this well water. The well has since been closed.

Although notifications were made throughout the year, there appears to be a special seasonal preference for the months of August, September and October.
