Malaria Fever, Causes, Prevention, And Treatment

malaria fever is a life-threatening disease. This is the commonest endemic disease in the tropics. It is caused by Plasmodium infection as a result of a mosquito bite. It is the commonest cause of fever in our environment. The female Anopheles mosquito is the vector.

There are four species of Plasmodium namely ;

1. Plasmodium Falciparium ;

3. Plasmodium Ovale ;

2. Plasmodium Malaria ;

4. Plasmodium Vivax.

If a female Anopheles mosquito bite and suck the blood of a person having malaria fever, the mosquito becomes infected. The male and female gametocytes in the infected blood grow and mature in the gastrointestinal tract of the mosquito. The male gamete is known as the microgamate exflagellates.

Fertilization then occurs to produce a zygote. The zygote progressively develops into 00 kinete, young ooocyte and segmenting oocyte. The oocyte rupture to release sporozoites into the salivary gland of the mosquito.

Should this mosquito bite another person, it deposits the sporozoites into the person's bloodstream. These sporozoites move from the blood into the liver within thirty minutes. Here they undergo development and break up hemoglobin to get oxygen and are therefore pigmented. These pigmented sporozoites are called merozoites.

From the liver, these merozoites are released into the bloodstream. Most of these merozoites invade the red blood cells and some can re-infect the liver in a secondary exoerythrocytic cycle, Development of the merozoites in the red blood cell produce trophozoites.

Further multiplication of the trophozoites gives rise to schizonts. Schizonts rupture to produce more merozoites. These merozoites differentiate into immature gametes which eventually mature to male and female gametes.

PREVENTION OF MALARIA FEVER

Good environmental sanitation by a clearing of surrounding bushes providing adequate drainage.
Providing mosquito nets.
Taking daraprim tablets once every week especially amongst pregnant woman and sicklers.

CURATIVE MANAGEMENT OF MALARIA FEVER

Being the commonest disease condition in our environment many drug companies have research on one form of treatment modalities or the other and have come up with as many antimalarial drugs as possible. But by far the most effective of all remain chloroquine and it has remained the mainstay of
treatment.

An antihistamine may be added for those who react to chloroquine. The list of anti-malaria drugs is given below and it is up to the clinician to use any one of his choices.
