IVCC was privileged to play its part in the Kigali Malaria and Neglected Tropical Diseases Summit that took place on the fringes of the Commonwealth Heads of Government meeting in June.

Governments, the private sector, and philanthropists pledged to help accelerate the global fight to beat malaria and neglected tropical diseases with commitments totalling more than $4 billion.

These $4 billion commitments come at a time when malaria is rising, driven in part by the growing threat of insecticide resistance which is inhibiting the efficacy of bet nets which, for so long have proven to be the most effective intervention tool, helping to halve malaria deaths since the turn of the century.

New insecticides for bed nets are urgently needed to support best practice insecticide resistance management which will prolong the efficacy of these lifesaving interventions.  In addition, new vector control tools are required to also address the growing threat of outdoor biting.

With the support of philanthropic and government funders and industry partners, IVCC is leading the way in helping to develop and bring to market these innovative vector control tools.

The Summit, hosted by the Rwandan Government, featured keynote speeches from HRH Prince of Wales, His Excellency President Kagame, Melinda French Gates, and World Health Organisation’s Director General, Dr Tedros Ghebreyesus.

Goodbye Malaria is an initiative started by African entrepreneurs who believe that today’s generation can create innovative solutions to the continent’s problems and ultimately change the way the world sees Africa. Since the turn of the century, vector control has proven to be one of the most effective strategies for reducing malaria incidence and deaths. Since 2000, more than 80% of the reduction in malaria prevalence in Africa can be attributed to indoor residual spraying (IRS) and insecticide-treated nets (ITNs).

Traditionally, men have been responsible for implementing IRS in sub-Saharan Africa. However, this traditional view is increasingly being challenged as more organisations recognize that women should play a more significant role in conducting and leading spray operations.

Recent entomological field results from Project BITE under IVCC’s Indo-Pacific Initiative (IPI) have shown that forest packs containing bite prevention tools offer significant protection from landing mosquitoes. The results come from trials that UCSF-MEI, IVCC’s lead partner on BITE, conducted in Mondulkiri province, Cambodia, with the local non-profit Health Forefront Organization.

The entomological trials were conducted in an area directly adjacent to forest and was comprised of 7 temporary shelters designed to mimic short-term dwellings used by people when working or travelling in the forest. Inside each shelter, one of the bite prevention tools, or a combination of all tools, or a control, were used while volunteers collected mosquitoes via Human Landing Catches (HLC) over a 12-hour period.

Over 49 nights of collections, the entomological field study demonstrated that all products – both on their own and in combination – are highly efficacious at preventing mosquitoes from landing. In fact, all products and combinations reduced mosquito landings by at least 60% compared to the control, while the spatial repellent alone and the combination of all products reduced landings by approximately 95%.

Project BITE aims to evaluate the effectiveness of forest packs containing a spatial emanator, topical repellent, and insecticide-treated clothing when deployed to forest dwellers, goers, and rangers in the Greater Mekong Subregion (GMS). Semi-field trials completed in Thailand in 2021 demonstrated that bite prevention tools not only prevent mosquitoes from landing but can also kill and delay host-seeking.

Following the entomological field studies, Project BITE is currently planning on how best to scale-up use of these tools and further evaluate their epidemiological impact, acceptability, use and cost-effectiveness among high-risk forest-exposed populations.

IVCC and its partners are hopeful that the evidence generated by BITE will help make the case to national programmes and donors on the effectiveness of bite prevention tools delivered in forest packs in the fight against outdoor malaria transmission.
