HE BURDEN AND CHALLENGES OF NEONATAL TETANUS IN KILIFI DISTRICT, KENYA--2004-7
Insights
Neonatal tetanus (NNT) incidence rose in Kilifi, Kenya, between 2004 and 2007, indicating a growing public health concern. Low immunisation coverage among women of childbearing age contributed to this trend.
Area of Science:
- Public Health
- Epidemiology
- Immunisation Studies
Background:
- Neonatal tetanus (NNT) remains a significant public health challenge in many developing regions.
- Understanding NNT incidence and associated risk factors is crucial for effective intervention strategies.
Purpose of the Study:
- To determine the incidence and geographical distribution of neonatal tetanus (NNT) in Kilifi district, Kenya, from 2004 to 2007.
- To assess trends in routine immunisation coverage, catch-up campaigns, and mop-up activities during the study period.
Main Methods:
- A retrospective study design was employed.
- Data were collected from children diagnosed with NNT attending health facilities in Kilifi district.
- Analysis included incidence rates, geographical mapping, and immunisation coverage data.
Main Results:
- NNT incidence in Kilifi increased from 0.6 to 1.0 per 1000 live births between 2004 and 2007.
- Over half of Kilifi district was identified as a high-risk area for NNT, with 19 out of 36 locations classified as public health problems.
- While TT2+ immunisation coverage for pregnant women rose significantly (22% to 98%), coverage for women of childbearing age remained low (4% to 17%).
- All NNT cases were home deliveries, and 83% involved the application of potentially infectious materials to the umbilical cord.
Conclusions:
- Neonatal tetanus posed an increasing threat in Kilifi district from 2004 to 2007.
- Low immunisation coverage among women of childbearing age was a key contributing factor.
- Inconsistent data capture for TT immunisation, conflating pregnant women and women of childbearing age, hindered accurate coverage assessment.
Objectives:
To describe the incidence of neonatal tetanus (NNT) and to describe the trends between 2004 and 2007; to show the geographical distribution of NNT in Kilifi district and to describe routine immunisation coverage, catch-up campaigns and mop-ups.
Design:
Retrospective study
Setting:
Kilifi district, Coastal Kenya
Subjects:
Children diagnosed with Neonatal Tetanus (NNT) attending Health facilities in the District.
Results:
The incidence of NNT in Kilifi increased from 0.6 in 2004 to 1.0 per 1000 live births in 2007. Over 50% of Kilifi district was a high risk area for NNT. It was a public health problem (> 1 per 1000 live births) in 19/36 locations. Immunisation (TT2+) increased from 4% in 2004 to 17% in 2007 for women of childbearing age and from 22% to 98% for pregnant women in the same period. All cases of NNT were delivered at home. 83% of NNT cases had potentially infectious materials applied to their cords.
Conclusions:
Neonatal tetanus was an increasing problem in Kilifi district in the period 2004-2007. Immunisation coverage was low for women of childbearing age. TT immunisation data capture was a mix-up (pregnant women andwomen of childbearing age) at various health facilities and was a challenge to accurate estimates of TT2+ immunisation coverage.
