ACCORDING to Dr. Guillermo Iliviera (Bol. Of. San. Panamer., 22, 987; 1943), medical superintendent of the National Leprosarium of the Dominican Republic, 212 cases of leprosy have been treated there during the period 1922–42, or are still confined there. 142 were men and 70 women. There were 75 deaths and 23 births. 147 cases were from the southern zone, while 44 were from the northern zone; the central area was practically free from the disease. Estimating the total number of lepers in the Republic both in and out of the leprosarium at 224, one obtains a ratio of one leper per 8,500 inhabitants, which is much lower than that of India (1 per 3,000) and Japan (1 per 1,000).
