All these cases occurred among natives of the Sudan. In 1926 five of a total of 12 cases occurred in Kassala. In 1927 thirteen of a total of 16 cases occurred in Kassala. In 1928 seven of a total of 12 cases occurred in Kassala. It is interesting to note that only one case is reported from Red Sea Province, which is inhabited by the same Hamitic races which contribut the cases to Kassala Province.

This may be due to the fact that Port Sudan hospital is largely a town hospital, and deals with a smaller percentage of the non-Arabised Hamitic population.

RABIES.

No cases of this disease were reported in the s'udan before the year 1924, but the disease has now definitely established itself and appears to be on the increase. Cases of rabies in dogs or other animals occurred in Kordofan, the Nuba Mountains, Bahr-el-Ghazal, Kassala and the Red Sea Provinces. Of these, the Red Sea Province had not previously been known to be infected.

Five human cases occurred (they were all fatal). Of these cases, four came under treatment. The distribution of the cases is given below :—

Kordofan Province—Abu Zabad 1 case.

,, ,, Rahad 1 ,, ,, ,, Rashad 1 ,, Red Sea ,, Tokar 1 ,, Kassala ,, Kassala 1 ,, Sixty persons who had been bitten by, or had come into close contact with, rabid dogs received treatment with antirabic vaccine ; of these two died before

they had completed the course of treatment.

The following measures were taken to diminish the danger of further spread of the disease :—

(i) A regulation was put in force to prevent the transport of dogs by rail or steamer except on the certificate of a veterinary officer, or in his absence, of a magistrate.

(ii) Measures were taken to render more complete the destruction of homeless or uncared-for dogs.
