Reductions in malaria cases have stalled after several years of decline globally, according to the new World malaria report 2018. To get the reduction in malaria deaths and disease back on track, WHO and partners are joining a new country-led response, launched today, to scale up prevention and treatment, and increased investment, to protect vulnerable people from the deadly disease.
For the second consecutive year, the annual report produced by WHO reveals a plateauing in numbers of people affected by malaria: in 2017, there were an estimated 219 million cases of malaria, compared to 217 million the year before. But in the years prior, the number of people contracting malaria globally had been steadily falling, from 239 million in 2010 to 214 million in 2015.
In 2017, approximately 70% of all malaria cases (151 million) and deaths (274 000) were concentrated in 11 countries: 10 in Africa (Burkina Faso, Cameroon, Democratic Republic of the Congo, Ghana, Mali, Mozambique, Niger, Nigeria, Uganda and United Republic of Tanzania) and India. There were 3.5 million more malaria cases reported in these 10 African countries in 2017 compared to the previous year, while India, however, showed progress in reducing its disease burden.
Despite marginal increases in recent years in the distribution and use of insecticide-treated bed nets in sub-Saharan Africa – the primary tool for preventing malaria – the report highlights major coverage gaps. In 2017, an estimated half of at-risk people in Africa did not sleep under a treated net. Also, fewer homes are being protected by indoor residual spraying than before, and access to preventive therapies that protect pregnant women and children from malaria remains too low.
In line with WHO’s strategic vision to scale up activities to protect people’s health, the new country-driven “High burden to high impact” response plan has been launched to support nations with most malaria cases and deaths. The response follows a call made by Dr Tedros at the World Health Assembly in May 2018 for an aggressive new approach to jump-start progress against malaria. It is based on four pillars:
- Galvanizing national and global political attention to reduce malaria deaths;
- Driving impact through the strategic use of information;
- Establishing best global guidance, policies and strategies suitable for all malaria endemic countries; and
- Implementing a coordinated country response.
Catalyzed by WHO and the RBM Partnership to End Malaria, “High burden to high impact” builds on the principle that no one should die from a disease that can be easily prevented and diagnosed, and that is entirely curable with available treatments.
The report highlights some positive progress. The number of countries nearing elimination continues to grow (46 in 2017 compared to 37 in 2010). Meanwhile in China and El Salvador, where malaria had long been endemic, no local transmission of malaria was reported in 2017, proof that intensive, country-led control efforts can succeed in reducing the risk people face from the disease.
In 2018, WHO certified Paraguay as malaria free, the first country in the Americas to receive this status in 45 years. Three other countries – Algeria, Argentina and Uzbekistan – have requested official malaria-free certification from WHO.
India – a country that represents 4% of the global malaria burden – recorded a 24% reduction in cases in 2017 compared to 2016. Also in Rwanda, 436 000 fewer cases were recorded in 2017 compared to 2016. Ethiopia and Pakistan both reported marked decreases of more than 240 000 in the same period. (WHO)
