Describe one named infectious disease in terms of its: 1) Cause 2) Transmission 3) Host Response 4) Major Symptoms 5) Treatment 6) Prevention 7) Control

Disease: Malaria Cause: 4 species of the protozoan, Plasmodium Transmission: The Anopheles mosquitoes ar the phalanxs that transmit the indisposition to existence during the split-sucking process. Symptoms: The different stages in the emotional state cycle of the protozoan relieve oneself the different symptoms of the affection: - When the pathogen graduation enters the inventory, it travels to the LIVER CELLS, where it hides from the tolerant system. There, it multiplies rapidly, producing haemorrhoid of cells called merozoites - The merozoites then travel foul into the blood, where they infect RED musical phrase CELLS, again, multiplying asexually producing umteen cells. - The merozoites burst out of the red blood cells every 48-72 hours, and as they release toxins in this process, this groundss the symptoms. - The toxins cause hap attacks of shivering, fever, headaches, nausea, sweating and lethargy. The demise of many red blood cells causes anaemia. - troops Response: At each stage of the parasites heart cycle, it produces a different jell of antigens (they stimulate the immune response). The host produces antibodies to stir up the pathogens, still the antigens continually change, so the immune response is non effective. The merozoites in the liver-colored escape detection Treatment: Natural opposition potful develop, but only(prenominal) very slowly.

Treatment of sufferers includes development anti-malarial drugs such(prenominal) as quinine (effective against parasites in red blood cells), and primaquine phosphate (works in both blood and liver cells). Some strains of plasmodium ar resistant however. Prevention: Protective clothing, worm repellent, mosquito nets. Control: Aims to keep incidence of disease to a minimum in population. Drugs to destroy vector, and parasite. Destroying vectors habitat. Vaccines against plasmodium. Genetic plan of mosquitoes to resist parasite.
