According to the global health body, 15 countries accounted for 80 per cent of all malaria cases globally in 2016. Nigeria accounted for the highest proportion of cases globally at 27 per cent. Democratic Republic of Congo had 10 per cent, India 6 per cent and Mozambique recorded 4 per cent of the global malaria cases.
India had also witnessed a total of 331 malaria deaths in 2016, making it the highest in the entire Southeast Asia region. The malaria deaths in India were only less to WHO's Africa region where the figure soared as high as 33,997 for Democratic Republic of Congo.
"Odisha, the highest endemic state of India, reported an increase in cases in 2016 (to double the number in 2013). The other countries had no major outbreaks reported," according to report.
"In 2016, 85 per cent of estimated vivax malaria cases occurred in just five countries (Afghanistan, Ethiopia, India, Indonesia and Pakistan)," the report said.
In 2016, there were an estimated 445,000 deaths from malaria globally, compared to 446,000 estimated deaths in 2015.
"Plasmodium falciparum is the most prevalent malaria parasite in sub-Saharan Africa, accounting for 99 per cent of estimated malaria cases in 2016. Outside of Africa, P. vivax is the predominant parasite in the WHO Region of the Americas, representing 64 per cent of malaria cases, and is above 30 per cent in the WHO SouthEast Asia and 40 per cent in the Eastern Mediterranean regions," said the report.
The report also mentions between 2014 and 2016, a total of 582 million insecticide-treated mosquito nets (ITNs) were reported by manufacturers as having been delivered globally.

It says in 34 of 41 high-burden countries which rely mainly on external funding for malaria programmes, the average level of funding available per person at risk in the past three years (2014-2016) reduced when compared with 2011-2013.
Exceptions were Democratic Republic of Congo, Guinea, Mauritania, Mozambique, Niger, Pakistan and Senegal, which recorded increases.
"Among the 41 high-burden countries, overall, funding per person at risk of malaria remains below $2," said the report.
