The organization, in its World Malaria Report 2018 published a few days ago, said that 15 countries in sub-Saharan Africa and India carried 80 per cent of the global malaria burden.

The report partly reads, “In 2017, an estimated 219 million cases of malaria occurred worldwide, compared with 239 million cases in 2010 and 217 million cases in 2016.

“The 10 highest burden countries in Africa reported increases in cases of malaria in 2017 compared with 2016. Of these, Nigeria, Madagascar and the Democratic Republic of the Congo had the highest estimated increases, all greater than half a
