Records of 8,697 cases of tetanus seen over a period of 14 years are analysed. Overall mortality was 48.0%. Mortality in neonatal group was 86.38% whereas that in non-neonatal group it was 40.18%. Disease was seen more frequently in male than in female. Mortality in male was lower than in female. Incidence was highest in the first decade of life. Mortality was lowest (about 33%) in first two decades (excluding neonatal group). Mortality in neonatal group was highest (86.38%). Mortality was inversely related to length of incubation period. In cases with incubation period of 7 days or less, mortality was 58.26% in non-neonates and 94.15% in neonates. Mortality was very low (2.14%) in 2,100 cases who did not develop spasms. In cases with spasms mortality was inversely related to the length of period of onset. Temperature of 100 degrees F within first 24 hours of admission was an adverse factor and these cases had higher mortality. Cases were divided into five grades according to the severity. Mortality in each grade was significantly different from that in the other. Mortality was lower in otogenic tetanus while it was higher in post-abortion and post-injection tetanus. Tetanus following penetrating injury carried higher mortality whereas tetanus following abrasions had lower mortality. With head and face as the site of infection, mortality was low while it was high when the site of infection was a trunk. Results were similar with dose of A.T.S. ranging between 5,000 and 60,000 i.u. and tetanus immune globulin, whereas mortality was high with higher and lower dose of A.T.S. or with no A.T.S. Respiratory spasms, respiratory failure, respiratory complications and circulatory failure were the common causes of death.
