Analysis of 4,302 cases of schistosomiasis japonica

ABSTRACT

An analysis, in part, of 4,302 cases of Schistosomiasis japonica encountered in the different towns of ten provinces covered by the six field units during the fiscal year, 1949-1050 was presented as to age, sex, and grade incidenceAmong them, there was a predominance of males (60.07%) over females (39.93%). Among 3,004 whose age records were available, 1,680 (55.44%) were from 11 to 20 years old and 651 (an additional 21.68%) below ten years. It is evident from these figures that the majority of them contracted the disease before reaching the age of 20A new scheme of classification of patients, introduced for the first time, was used in selecting patients as subjects in connection with research projects undertaken by all field units. This scheme was found to be practical and useful but because it is new, it may further be improved. (Summary)
