Histopathological diagnosis and distribution of placental malaria. Legend: +: present; -: absent. The region of the grey circle with black dots in the background corresponds to the presence of parasites only in the placenta and represents active placental malaria. The region of the orange circle with orange background corresponds to the presence of malaria pigment only in the placenta and represents past placental malaria. The region where the two circles overlap corresponds to the presence of both parasites and malaria pigment and represents chronic placental malaria. The region of the black circle with white background corresponds to the absence of both parasites or malaria pigment and represents placenta free of malaria infection
