[A study on risk factors and control of neonatal tetanus during 1975-1990 in Yichang City].
Retrospective survey on the mortality of 21 cases of neonatal tetanus during 1975-1990 and their case-control study on death risk factors were reported in Yichang City. Surveillance and control of neonatal tetanus were emphasized on suburbs. Serological survey of tetanus antibody in women aged 15 to 40 and mothers and their newborn babies were carried out. The protective rate was 3.75% (GMT = 0.0014 IU/ml). The result showed that tetanus antibody in the women of childbearing age was at the lowest level. There was a significant positive correlation through vertical transmission between mothers and their newborn babies (r = 0.7096, P < 0.0005). And the successful immunization in 65 pairs of children was 100%. It was suggested that we should consolidate EPI and promote maternal and child health plan and a primary-health-care program in Yichang City.
