Plasmodium falciparum malaria in a pregnant woman six months after stay in an endemic area

: A case of P. falciparum malaria in a 22 year old West African primigravida with no possible exposure to malaria seven months before detection and six months before the infection became symptomatic is presented. We connect the altered immunity against malaria induced by the pregnancy with the presence of subclinical low-level persistent parasitaemia in semi-immune individuals from areas with intense malaria transmission.
