Permethrin-Treated Baby Wraps Significantly Reduce Incidence of Clinical Malaria in Children

A recent trial conducted in Uganda demonstrated the efficacy of using permethrin-treated baby wraps to prevent clinical malaria in children aged 6 to 18 months. The study, published in the New England Journal of Medicine, involved 400 mother-child pairs who were randomly assigned to use either permethrin-treated wraps or sham-treated wraps. The results showed that the incidence rate of clinical malaria was significantly lower in the intervention group compared to the control group.

Key Takeaways:

  • The study involved 400 mother-child pairs who were randomly assigned to use either permethrin-treated wraps or sham-treated wraps.
  • The primary outcome was clinical malaria in the children, as defined by fever and a positive malaria rapid diagnostic test.
  • The incidence rate of clinical malaria was 0.73 cases per 100 person-weeks in the intervention group and 2.14 cases per 100 person-weeks in the control group (incidence rate ratio, 0.34; 95% CI, 0.23 to 0.51; P
  • Rash was reported more often in the intervention group than in the control group (8.5% vs. 6.0% of participants).
  • Maternal use of permethrin-treated baby wraps significantly reduced the incidence of clinical malaria in the children.

Statistics:

  • 400 mother-child pairs were enrolled in the study.
  • 200 pairs were assigned to the intervention group and 200 to the control group.
  • The incidence rate of clinical malaria was 0.73 cases per 100 person-weeks in the intervention group.
  • The incidence rate of clinical malaria was 2.14 cases per 100 person-weeks in the control group.
  • The incidence rate ratio was 0.34 (95% CI, 0.23 to 0.51);
  • Rash was reported in 8.5% of participants in the intervention group and 6.0% of participants in the control group.
