ABSTRACT
OBJECTIVE: To estimate the sensitivity of neonatal tetanus (NNT) surveillance in India. DESIGN: A comparison of two sets of data obtained from NNT mortality surveys and routine surveillance system. METHODS: NNT mortality surveys were undertaken in 1981, 1989 and 1992 using 30 cluster sampling technique. The data on reported incidence of NNT through routine surveillance system was taken from the published documents of Health Ministry and WHO. RESULTS: In 1981, the incidence of disease in a national survey was estimated to be 4 and 16.4 per 1000 live births in urban and rural areas, respectively. Follow up surveys in 1989 and 1992 estimated the overall incidence as 4 and 1.74 per 1000 live births, respectively. Comparing the reported and estimated by surveys, around 10% of NNT cases were reported. CONCLUSIONS: There is an urgent need to strengthen the routine surveillance system which at present grossly under-reports the NNT incidence in India.

The relationship between neonatal tetanus (NT) on one hand, and maternal tetanus immunization and other prenatal and natal practices on the other hand, was examined in a case-control study done at San Lazaro Hospital (SLH) in Manila from late 1990 to mid 1991. Included as cases were 54 patients diagnosed as NT on the basis of WHO criteria, and 50 controls who were patients 0-4 months of age, hospitalized at SLH during the study period and with no past history of tetanus. The result showed that the following were statistically associated with the risk of NT: home delivery (OR = 30.5); delivered by a traditional birth attendant (OR = 5.2); use of instrument other than scissors to cut the cord (OR = 19.3); traditional birth attendant who dressed the cord (OR = 12.7); and having less than two doses of tetanus toxoid (OR = 15.3). The need to intensify prenatal tetanus immunization, health education of the mothers as well as the training of birth attendants is evident from this study if NT has to be prevented.

The objective was to obtain the incidence rate of neonatal tetanus, perinatal mortality rate, and the coverage of health care utilization in the rural Muslim in the lower part of southern Thailand. In a retrospective field study, the rural populations of Narathiwat, Yala and Pattani provinces were studied by cluster sampling technique. The still birth rate and early neonatal mortality rate were 15.3 per 1,000 births and 11.2 per 1,000 live births, respectively. The maternal mortality rate was 1.7 per 1,000 live births. 55% of all pregnancies received 2 injections of tetanus toxoid, 80% of deliveries were performed by traditional birth attendants. The incidence rate of neonatal tetanus was 0.9 per 1,000 live births. The coverage of health service for prevention of perinatal mortality was low and these perinatal and maternal mortality rates were unacceptably high. In contrast, the incidence of neonatal tetanus was not particularly high for unknown reasons.
