Brief summary
Malaria during pregnancy remains an important public health issue in endemic countries. Most cases of malaria in pregnant women are asymptomatic, and can contribute to adverse outcomes, such as maternal and neonatal anaemia as well as low birth weight. Infections that do not cause symptoms (sub-clinical infections) - particularly in low transmission settings -remain difficult to diagnose during pregnancy but can contribute to adverse outcomes e.g. growth restriction, premature birth, miscarriage and stillbirth. The Bill & Melinda Gates Foundation (BMGF) has supported the development of an HRP2-based high sensitivity rapid diagnostic tests (HS-RDT) that has analytical sensitivity ten times better than current RDTs and a sensitivity near 80% when compared to the 'gold standard' of quantitative polymerase chain reaction (qPCR). In this regard, the new HS-RDT may be a promising diagnostic and screening test for subclinical malaria during pregnancy. The overall aim is to compare the performance of novel high sensitivity rapid detection tests with conventional rapid diagnostic tests for Plasmodium falciparum malaria infection in pregnant women in Papua New Guinea
Interventions
A single finger-prick blood sample will be collected and used to test participants with the HS-RDT. The results of the results of the test will not be used for treatment purposes nor used to inform patient care.
