Without clean water, more than 1a million women lose their lives every year with sanitation-related hookworm, which causes maternal anaemia and preterm births.

<h3>What is the relation between hookworm and anemia?</h3>

In regions where hookworm incidence is greater than 20% and anemia prevalence is larger than 40%, routine preventative chemotherapy for pregnant women after the first trimester is advised, as was already mentioned. In places above and below this guideline threshold, a subset analysis of the effects of maternal hookworm infection on anemia was conducted. Pregnant women with hookworm infection had a higher likelihood of having anemia than pregnant women without hookworm, as would be expected in locations where the prevalence of hookworm is more than 20% P 0.001. Intriguingly, pregnant women with hookworm infection had a higher chance of having anemia with a cOR of 6.07, P 0.001, in regions where the prevalence of hookworm was less than 20%.
