Why is this so important? According to Fisk and Atun:
Worldwide, there are 536,000 maternal deaths annually, while nearly half the 13.5 million under-five child deaths occur as antepartum, intrapartum, or neonatal deaths.In developing nations, the problems are even more pronounced because of their increased burden of disease. We do not know how to treat most tropical diseases in pregnant women, but that does not mean they are not getting sick and dying. I support careful testing of all people with no qualifications. Malaria, however, leads to a mortality rate of 50% in pregnant women in their 3rd trimester, according to White et al, and we do not know how to treat it. There is no easy answer. Clinical trials are difficult as it is, let alone one in pregnant women or in a third world country.
