Results from MENTOR’s trial of an innovative malaria control tool called Durable Wall Lining (DWL) have been published in the Malaria Journal. Analysis of the data from the trial in Liberia shows it has the potential to provide longer lasting, continuous protection from malaria. The material was found to be more effective than commonly used malaria control tools.

Richard Allan, MENTOR CEO conceived the product which went on to be developed and manufactured as a prototype by Vestergaard. Richard explains its benefits:

“The successful trial of this tool is significant for the effective control of malaria in areas where the coverage and use of long-lasting insecticidal nets is patchy.

It is the first time a material treated with two novel non-pyrethoid class insecticides has been tested and proven to offer protection against malaria over an extended time.

The design of the material and how it is installed provides protection in all areas of the home throughout the day and night, not just when people are sleeping under nets. Once installed it offers continuous protection unlike a seasonal spraying campaign.

The fibrous material is easily attached to the interior walls and ceiling of any type of rural housing. It can cover open eaves which greatly reduces mosquitos’ entry into the home without impacting airflow.

DWL is manufactured in colours to suit local preferences, which improves the aesthetic as well as provides disease protection. This dual function results in high rates of acceptance and retention in communities.

It addresses the challenge faced by internally displaced persons and refugees that return to their homes and become more vulnerable to malaria because of a lack of established disease control activities.

DWL can potentially sustain the progress made in countries that are moving towards elimination but still have low levels of transmission. The lining also deters termites which protects the structural integrity of dwellings and ensures they do not need to be rebuilt every five years.

We are encouraged about what this could mean for the advancement of malaria control and are committed to develop tools that are effective in the fight against malaria.”

Richard will present the study at RBM’s Annual Vector Control Working Group Meeting in Ghana in February.
