The problem, the consequences, and rapid testing solutions
Malaria is a preventable and treatable infectious disease transmitted by mosquitoes that killed more than 627,000 people in 2020, with sub-Saharan Africa accounting for 93% of global deaths.1 Children under five accounted for 80% of all deaths in the region.1
Because malaria is a global crisis that affects mostly poor women and children, malaria perpetuates a vicious cycle of poverty in the developing world. Malaria-related illnesses and mortality cost Africa’s economy alone USD 12 billion per year and reduces GDP growth by 1.3 percent annually.2
The Problem
While progress has been made against the spread of malaria in Asia and the Americas, it has stalled in sub-Saharan Africa since 2015 for several complex reasons: (1) More people in sub-Saharan Africa live in areas of risk of malaria, (2) funding has plateaued in the countries of this region, (3) coverage of vector control interventions has flattened or declined, and (4) access to quality care is inadequate.3
Additionally, asymptomatic Plasmodium carriage in low transmission settings has been suggested to be responsible for 20–50% of all malaria transmission in those settings.4

The Consequences
Vector control offers an important strategy to control disease transmission and to prevent infection.1 Two important components of vector control are insecticide-treated nets (ITNs) and indoor residual spraying (IRS).1 However, progress in global malaria control is threatened by emerging resistance to insecticides among certain mosquito species such as Anopheles. The latest World Malaria Report states that 78 countries have reported mosquito resistance to at least 1 of the 4 commonly-used insecticide classes in the period 2010–2019. Furthermore, mosquito resistance was reported to all main insecticide classes in 29 countries.1
