A Simple Wrap Making a Big Difference: New Study Finds Treated Cloths Cut Malaria in Babies by 66%

A new study published in the New England Journal of Medicine, one of the world’s most respected medical journals, has found that a simple, culturally familiar tool could dramatically cut malaria rates among young children in Africa.

Researchers from the University of North Carolina and Mbarara University of Science and Technology in Uganda tested whether treating baby-carrying wraps with a small amount of insect repellent could protect infants from malaria. These wraps, known locally as lesu, are used daily by mothers to carry and cover their babies.

Over 400 mothers and their children (ages 6 to 18 months) participated in the study from 2022 to 2024. Half were given wraps treated with permethrin, a widely used insect repellent, and the other half received untreated wraps. Everyone also received mosquito bed nets.

What They Found

The results were striking:

•   Babies wrapped in permethrin-treated cloths had 66% fewer malaria cases than those in untreated wraps.

•   The rate of infection dropped from 2.14 cases per 100 person-weeks in the control group to 0.73 in the treated group.

•   There were also fewer malaria-related hospitalizations (3.5% vs. 8.5%).

•   The only minor side effect reported was a mild rash in a small number of babies (8.5% vs. 6%).

Why This Matters

Malaria remains one of the leading killers of children under five in Africa. Even with bed nets and preventive medicines, outdoor mosquito bites, especially during the day, remain a considerable challenge. This approach leverages a common cultural practice to deliver protection in a natural way.

By simply adding pest control tools to the wraps many mothers already use, scientists found a way to protect babies without changing habits or adding complex technology.

These data-backed results show promise for saving countless young lives.

The next step is figuring out how to make these wraps widely available. A slight change in fabric treatment could mean a big step forward in the fight against malaria.
