Reductions in malaria cases have stalled after several years of decline globally, according to the new World malaria report 2018.
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.
This has prompted WHO and partners to scale up prevention and treatment, and increased investment, to protect vulnerable people from the deadly disease.
“Nobody should die from malaria. But the world faces a new reality: as progress stagnates, we are at risk of squandering years of toil, investment and success in reducing the number of people suffering from the disease”, says Dr Tedros Adhanom Ghebreyesus, WHO Director-General.
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.
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.
