Malaria during Pregnancy

Abstract: One hundred and twenty-five million women in malaria-endemic areas become pregnant each year (see Dellicour et al. e1000221 [2010]) and require protection from infection to avoid disease and death for themselves and their offspring. Chloroquine prophylaxis was once a safe approach to prevention but has been abandoned because of drug-resistant parasites, and intermittent presumptive treatment with sulfadoxine-pyrimethamine,which is currently used to protect pregnant women throughout Africa, is rapidly losing it… Show more
