Global health authorities need to counter a worrying lull in the fight against malaria by focusing their efforts on the near-dozen mostly African countries where it claims most lives, the World Health Organization said.
After several years of steady declines, annual cases of the mosquito-borne disease are levelling off, the U.N. health agencyâs 2018 malaria report showed on Monday.
To get back on track, the current broad approach to combating it must be fine-tuned, said WHO malaria chief Pedro Alonso. âThe problem is that we have stalled progress,â he told Reuters in a telephone interview.
Scientists are working on potential malaria vaccines and on new ways to control mosquito populations, but with the WHO report showing around half of Africans at risk still not sleeping under insecticide-treated nets in 2017, the world cannot simply afford to wait for those to materalise.
âSo we need to do better at having a greater impact with the tools and resources we have,â Alonso said.
The report showed around 435,000 deaths and 219 million malaria cases in 2017, both little changed from 2016. Global case numbers fell steadily from 239 million in 2010 to 214 million in 2015, and deaths from 607,000 to around 500,000 from 2010 to 2013.
The WHOâs new âprecision public healthâ approach is to focus in on the areas where malaria is hitting hardest, Alonso said.
In 2017, the report found, around 70 percent of all cases and deaths were concentrated in 10 African countries - including Cameroon, Nigeria and Democratic Republic of Congo - plus India.
The plan involves making better use of detailed data to target areas where bednets or more widespread use of indoor spraying would have a greater impact. Protection for pregnant women and children from malaria also remained too low, the report found.
âWe recognise we have to do something different â now,â WHOâs Director-General Tedros Adhanom Ghebreyesus said.
The report found some pockets of progress: India recorded a 24 percent reduction in malaria cases in 2017 and Rwanda 436,000 fewer. Ethiopia and Pakistan also both reported marked decreases.
