1. Passive health centre based delivery approach (PHC). IPT/SP will be delivered to all pregnant women presenting to the health centre either for ANC visit or for care seeking consultation. Drugs will be administered as a directly observed treatment (DOT). Some collation may be given to women as some of them refuse to take drugs because they have not eaten before. This approach, which is the most likely to be applied by the MOH, will serve as the control one.
