@simrin-- That's true but it's not always possible for people to prevent malaria infections or plan pregnancies accordingly. Most people in malaria-ridden regions of the world don't have the means to do this anyway.
I think the effects of malaria in pregnancy depends on many factors that we can't completely cover here. But two that come to mind right away is the malaria species that is being dealt with and the immunity of the mother.
The article already talked about immunity a little bit. I think that women who have been infected with malaria previously might do better with a malaria infection during pregnancy because their immune system already recognizes the virus. So the side effects might not be as serious as it would be if it was the first infection.
Also, there are several different types of malaria species like plasmodium falciparum (in Africa), p.vivax (in Southeast Asia) and
p.falciparu (in East Asia). The intensity and symptoms of the disease vary depending on this as well.
So the effects of malaria disease during pregnancy is pretty specific to the person, the malaria species and their immunity condition.
