Malaria is caused by the bite of the female Anopheles mosquito, if the mosquito itself is infected with a malarial parasite.
There are five kinds of malarial parasites — Plasmodium falciparum, Plasmodium vivax (the commonest ones), Plasmodium malariae, Plasmodium ovale and Plasmodium knowlesi.
Plasmodium ovale:
P ovale rarely causes severe illness and there is no need for panic because of the case detected in Kerala.
P ovale is very similar to P vivax, which is not a killer form. Symptoms include fever for 48 hours, headache and nausea, and the treatment modality is the same as it is for a person infected with P vivax. P ovale is no more dangerous than getting a viral infection.
It is termed ovale as about 20% of the parasitised cells are oval in shape.
P ovale malaria is endemic to tropical Western Africa. P ovale is relatively unusual outside of Africa.
