In the typhoid fever recording cards in the period from 1973 to 1976, 1015 cases were available in this study. Among these cases typhoid fever germs were detected in 740 patients and 130 cases were carriers. Epidemiological study on typhoid fever was performed mainly on these cases, and the following results were obtained.
(1) Typhoid fever appeared frequently in Kinki District centered at Osaka and Hyogo Prefectures. In the aspect of the phage type, E 1, D 2 and M 1 frequently appeared recently; the type transfers with time and many phage types have locality; thus, pursuing the phage type serves to establish the policy to control the disease.
(2) The incidence of the female patients were less than that of the male ones, but the female carriers were twice as many as the male ones; and the age distribution shifted to the older side.
(3) Administration of antibiotics before a confirmation of the diagnosis was not so influential to the clinical decision of diagonosis, but the term required for establishment of diagnosis was surely prolonged.
(4) The past history of the typhoid fever was found in 3.8% of the patients, in whome the germs were detected and in 13.1% of the carriers as well.
From the above result obtained, it will be necessary for the typhoid fever policy with more precise information and control to know the tendency of typhoid fever more scientificly and to perform a consistent control through diagnosis, therapy and treatment after curing, as well as to grasp the cases in the early stage where they are only doubted to be infected in the system of information management.
