After unprecedented global success in malaria control, progress has stalled, according to the World malaria report 2017. There were an estimated 5 million more malaria cases in 2016 than in 2015. Malaria deaths stood at around 445 000, a similar number to the previous year.
An estimated US$ 2.7 billion was invested in malaria control and elimination efforts globally in 2016. That is well below the US $6.5 billion annual investment required by 2020 to meet the 2030 targets of the WHO global malaria strategy.
The report shows that, in 2016, there were an estimated 216 million cases of malaria in 91 countries, up from 211 million cases in 2015. The estimated global tally of malaria deaths reached 445 000 in 2016 compared to 446 000 the previous year.
While the rate of new cases of malaria had fallen overall, since 2014 the trend has levelled off and even reversed in some regions. Malaria mortality rates followed a similar pattern.
The African Region continues to bear an estimated 90% of all malaria cases and deaths worldwide. Fifteen countries – all but one in sub-Saharan Africa – carry 80% of the global malaria burden.
“Clearly, if we are to get the global malaria response back on track, supporting the most heavily affected countries in the African Region must be the primary focus,” said Dr Tedros.
In most malaria-affected countries, sleeping under an insecticide-treated bednet (ITN) is the most common and most effective way to prevent infection. In 2016, an estimated 54% of people at risk of malaria in sub-Saharan Africa slept under an ITN compared to 30% in 2010. However, the rate of increase in ITN coverage has slowed since 2014, the report finds.
The African Region has seen a major increase in diagnostic testing in the public health sector: from 36% of suspected cases in 2010 to 87% in 2016. A majority of patients (70%) who sought treatment for malaria in the public health sector received artemisinin-based combination therapies (ACTs) – the most effective antimalarial medicines.
However, in many areas, access to the public health system remains low. National-level surveys in the African Region show that only about one third (34%) of children with a fever are taken to a medical provider in the public health sector.
