5. Study Description
Brief Summary
The purpose of this study is to determine whether repeated courses of sulphadoxine-pyrimethamine (SP) in combination with azithromycin given at Antenatal Clinic, leads to lower rates of low birth weight deliveries (<2.5 kg) among Papua New Guinean women, than the current standard treatment of SP and chloroquine.
