P. ovale is a plasmodium species that causes malaria. It was first described in 1914 and is primarily found in sub-Saharan Africa and some Pacific islands. Unlike P. vivax, P. ovale can infect people without the Duffy blood group, explaining its higher prevalence in Africa. Symptoms of P. ovale malaria generally appear 12 to 20 days after infection and include fevers every 48 hours along with sweats and chills. Diagnosis is made by examining blood films for trophozoites, schizonts and gametocytes in red blood cells, which are often enlarged and oval-shaped. Treatment involves early diagnosis, early antimalarial treatment, vector control measures, and health education

3. sub-Saharan Africa and islands in the western Pacific
P. ovale is able to infect individuals who are
negative for the Duffy blood group, which is the
case for many residents of sub Saharan Africa. This
explains the greater prevalence of P. ovale (rather
than P. vivax) in most of Africa.

5. symptoms generally appear 12 to 20 days after the
parasite has entered the blood.
Malaria attack (cardinal signs) /tertian every48hours:
Fever stage
Sweat stage
Cold stage

Trophozoites, schizont and gametocyte are present in
peripheral blood
Infected RBCs are enlarged , mostly with oval shape.
