Said reduction dropped from 38.7 in 1970 to 22.8 per thousand live births in 1976, for a diminution of 41.5%. The early neonatal decreased from 18.2 to 12.3 per thousand live births for a drop of 32.7%. The late noenatal decreased from 5.3 to 2.30/100 live births with 57.2% reduction and the postneonatal dropped from 15.2 to 8.2 per thousand live births for a diminution of 46.5%. Infantile mortality is reported for the different departments and the order in which the main causes of death are grouped is stressed as follows; 1st, perinatal affections (B43-B44); 2nd, congenital anomalies (B42); 3rd, influenza and pneumonia (B31-B32); 4th, enteritis and other acute diarrheal diseases (B4) AND 5th, sepsis (A21). The average number of puericulture office visits per infant under 1 year of age increased from 2.7 to 6.7. Institutional births increased from 93.3 to 97.8%. The steps taken to achieve these results are described.
