- Abstract
Neonatal tetanus (NT) elimination, <1 case per 1000 live births (LB), was assessed at district level in Zimbabwe using a combined lot quality assurancecluster sampling survey (LQACS). Three of the highest risk districts were selected. NT was considered eliminated if fewer than a specified number of NT deaths (proxy for NT cases) were found in the sample determined using operating characteristic curves and tables. TT2+ vaccine coverage was measured in mothers who gave birth 113 months before the survey and women aged 1549 years. NT was considered as eliminated, TT2+ coverage was 78% (95% CI 7182%) in women aged 1549 and 83% (95% CI 7689%) in mothers. The survey cost US$ 30000 excluding costs of consultants. NT incidence was below the elimination threshold (<1/1000 LB) in the surveyed districts and probably in all districts. LQACS is a practical, relatively cost effective field method which can be applied in an African setting to assess NT elimination status.
