Brief Summary:
A Phase III malaria prevention trial was conducted in two camps of Liberian refugees in Sierra Leone using Insecticide Treated Polyethylene Sheeting ITPS or untreated polyethylene sheeting UPS randomly deployed to defined sectors of each camp The ITPS was impregnated with pyrethroid insecticide during manufacture In Largo camp the ITPS or UPS was attached to inner walls and ceilings of shelters while in Tobanda the ITPS or UPS was used to line the ceiling and roof only Cohorts of children up to 3 years of age were cleared of malaria parasites and monitored for up to 8 months post construction for possible malaria re-infection Installation teams and refugee groups were blinded as to whether the sheeting was insecticide treated or not
Detailed Description:
During the last decade public and private sector organisations under the leadership of the Roll Back Malaria RBM Initiative have recognised the need to work together to bring complementary expertise to the task of identifying and developing vector control tools appropriate to humanitarian crises Insecticide Treated Polyethylene Sheeting ITPS is one such tool emerging from this process and is being produced commercially ITPS is based on the standard polyethylene sheeting that is issued routinely as temporary shelter for people affected by emergencies During manufacture the pyrethroid insecticide deltamethrin is extruded with the polyethylene into three-ply laminated sheets comprising an inner low-density laminate and two outer high-density laminates The insecticide release characteristics enable the deltamethrin to diffuse slowly to the outer surfaces and to become available for pick-up by any insect that lands on the surface Consequently ITPS has dual purpose to provide shelter but with vector-control potential Deployment and erection of ITPS is done in the same way as standard tarpaulin shelters
Until now evaluation of ITPS has been limited to small scale entomological testing in scientifically controlled environment entomological platforms in Asian and experimental huts in rural African settings Refer to Citation Section Before any novel control tool can go forward for recommendation by the WHO or be used routinely in humanitarian crises clear demonstration of impact on malaria morbidity in emergency refugee settings is essential A Phase III field evaluation was therefore conducted to evaluate the impact of ITPS on malaria incidence in young children in an area of intense transmission A unique feature of this trial was its setting - a true emergency - in two newly built refugee camps for Liberian refugees displaced to Sierra Leone The findings offer insight into the effectiveness of ITPS when used in a scenario for which it was purposefully designed
