Mathematical Modelling to Fight Malaria


In analysis printed right now in PLOS Computational Biology, a world analysis group used information from the WorldWide Antimalarial Resistance Community (WWARN), a world, scientifically impartial collaboration, to map the prevalence of genetic markers that point out resistance to Plasmodium falciparum – the parasite that causes malaria.

Lead creator Affiliate Professor Jennifer Flegg from the College of Melbourne mentioned malaria has devastating impacts on lower-income nations and efficient remedy is essential to elimination.

“The antimalarial drug sulfadoxine-pyrimethamine (SP) is commonly used in various preventative malaria treatment programs in Africa, particularly for infants, young children and during pregnancy. But we know its efficacy as a treatment is threatened in areas where resistance to SP is high,” Affiliate Professor Flegg mentioned.


“The statistical mapping tool we have developed is critical for health organisations to understand the spread of antimalarial resistance. The model takes in the data that is available and fills in the gaps by making continuous predictions in space and time.

Professor Karen Barnes, Head of WWARN Pharmacology and Elimination, said there is a rapidly increasing need for malaria chemoprevention (drugs that prevent malaria infections), but there are limited treatment options available.

“This well timed proof of the extent of SP resistance throughout Africa will assist to tell the place SP preventive remedy, alone or together with different antimalarials, could be almost definitely to have the best affect,” Professor Barnes said.

Professor Feiko ter Kuile, Head of WWARN’s Malaria in Pregnancy Scientific Group, said the updated model of SP resistance in Africa was long overdue.

“Loads of the resistance mapping has understandably targeted on the rising resistance to the artemisinin-based antimalarials used for treating malaria. Rising resistance of the malaria parasite to sulfadoxine-pyrimethamine in Africa has been a priority for a number of a long time. Nonetheless, simply accessible resistance information was missing,” Professor ter Kuile said.

“This examine combines all of the obtainable SP resistance information from the final twenty years in a single mannequin. It permits nationwide malaria management programmes and researchers to get much-needed information on the diploma of resistance in a given space in a given 12 months. This permits us to know higher the affect of sulfadoxine-pyrimethamine resistance on the effectiveness of those preventive interventions and decide if and when to think about various medicine for chemoprevention.”

Associate Professor Flegg said, “This analysis device ought to assist information well being insurance policies that can convey the World Well being Organisation’s formidable goal of eliminating malaria by 2030 one step nearer.”

The group included researchers from the College of Melbourne, the College of Oxford, Johnson C. Smith College, the College of Cape City and the College of Witwatersrand.

The analysis acquired funding from the Invoice & Melinda Gates Basis, the Smith Institute for Utilized Analysis, and the Australian Analysis Council.
