Consultant – Bioefficacy of long-lasting insecticidal nets in the Greater Mekong Sub-region, Anywhere At World Health Organization (WHO)


Bioefficacy of long-lasting insecticidal nets in the Greater Mekong Sub-region

( 2305339 )

Contractual Arrangement : External consultant

Contract Duration (Years, Months, Days) : 5 months

Job Posting: Jul 7, 2023, 2:03:47 PM


The Regional Artemisinin-resistance Initiative (RAI) was launched in 2013 in response to the emergence of artemisinin-resistant malaria in the Greater Mekong Sub-region (GMS). Funded by the Global Fund to Fight AIDS, TB, and Malaria, the RAI grants have invested more than USD 500 million in Cambodia, Lao PDR, Myanmar, Thailand, and Viet Nam, with a further grant for the 2024-2026 period. More details are available at

The RAI Regional Steering Committee (RSC), a multi-stakeholder governance body, provides strategic guidance, selects recipient implementers, and oversees grant implementation to track progress against program objectives and ensure funding is used in accordance with agreed strategic priorities.

The RSC has mandated the establishment of an Independent Monitoring Panel (IMP) to:

  •  Provide evidence-based, qualitative, and independent feedback, both to country leadership and to the RSC as the accountable body regionally, on the quality and effectiveness of RAI program implementation;
  •  Identify critical bottleneck issues affecting the achievement of programmatic goals;
  •  Support the RSC governance role by providing strategic analysis and recommendations for remedial actions.

Long-lasting insecticidal nets (LLIN) treated with synthetic pyrethroids have been shown to reduce malaria incidence by around 30% in forested areas in the GMS, despite the local malaria vectors in some areas being characterized by early outdoor biting. LLINs are widely used to reduce transmission and provide personal protection. To be eligible for donor-funded procurement and distribution schemes, LLIN products must attain and retain World Health Organization (WHO) prequalification status by passing safety, quality, and efficacy benchmarks. Predelivery inspections further test product quality before distribution.

Studies have reported that substandard LLINs have been distributed in several countries since 2013. There have been several reports of reduced bioefficacy of LLINs in the GMS. For example, bio-efficacy tests performed by the VBDC entomology laboratory in Gyogone indicated potential quality issues with LLINs. Researchers in Papua New Guinea concluded that an unreported change in coating formulation was the cause of the reduced product performance seen there.

The RSC and the IMP have identified a need for an independent review of changes in LLIN efficacy over the last decade and likely impact on progress towards malaria elimination as well as the response to reported LLIN bio-availability issues relevant to the GMS. In line with the IMP’s mandate, this is to inform Regional Steering Committee (RSC) and the implementation of the Global Fund grant.


The work to be performed in 2023 consists of a literature review followed by interviews with key informants and consultations with major stakeholders identified during the literature review and from the key informant interviews themselves. This work is to be performed remotely over six months.


Start date: 24 July 2023
