This book gives by tables and graphic representation the strides that have been made in child care in Spain in the last 50 years. In 1901 the infant mortality was 186 per 1,000 live births. In 1950 it was 63 per 1,000. These results have been obtained by intensive control of digestive disturbances and infectious diseases. Special effort is now being made on immunization against diphtheria and pertussis, with emphasis on BCG vaccination for tuberculosis.
