Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Annually, malaria affects an estimated 229 million people, causing 409,000 deaths (WHO 2019) mostly in Africa. Despite a substantial decline in malaria-related maternal and child deaths in recent years, progress in controlling malaria has been slower than anticipated and uneven across countries. COVID-19-related disruption of malaria control activities will likely further slow the pace and lead to an even greater burden in the near future.

One of the greatest challenges delaying progress in malaria elimination is antimalarial drug resistance. Recent reports of the emergence of artemisinin-resistant parasites in parts of Africa are the cause of even greater concern, since the loss of frontline treatment efficacy could bring about a dramatic reversal of progress.

Large-scale genetic surveillance of Plasmodium is an effective tool for rapid detection of changes in drug efficacy, enabling countries to switch to effective preventive and curative treatments when necessary. The implementation of genetic surveillance has proven very successful in small, low malaria burden countries. However, in large, high malaria burden countries such implementation is operationally and economically more complex.

Screening pregnant women attending Antenatal Care (ANC) services can be a practical and economical strategy for estimating malariometric parameters, with fewer limitations and challenges than conventional survey methodologies in children. The present study aims to demonstrate that this is also true for the genetic surveillance of antimalarial drug resistance.
