It is characterized by periodic attacks of chills,\r\nfever, nausea, vomiting, back pain, increased sweating anemia,\r\nsplenomegaly (enlargement of the spleen) and often-fatal\r\ncomplications.The malaria disease is caused by the multiplication of\r\nprotozoa parasite of the genus Plasmodium. Malaria in humans is due\r\nto 4 types of malaria parasites such that Plasmodium falciparum,\r\nPlasmodium vivax, Plasmodium malariae and Plasmodium ovale.\r\nP.vivax malaria differs from P. falciparum malaria in that a person\r\nsuffering from P. vivax malaria can experience relapses of the\r\ndisease. Between the relapses, the malaria parasite will remain\r\ndormant in the liver of the patient, leading to the patient being\r\nclassified as being in the dormant class. A mathematical model for\r\nthe transmission of P. vivax is developed in which the human\r\npopulation is divided into four classes, the susceptible, the infected,\r\nthe dormant and the recovered. In this paper, we formulate the\r\ndynamical model of P. vivax malaria to see the distribution of this\r\ndisease at the district level.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 20, 2008"}
