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 waiters that transmit the indisposition to existence during the split-sucking process. Symptoms: The different stages in the animation cycle of the protozoan condone oneself the different symptoms of the illness: - When the pathogen initiative enters the stock, it travels to the LIVER CELLS, where it hides from the insubordinate system. There, it multiplies rapidly, producing haemorrhoid of cells called merozoites - The merozoites then travel tail into the blood, where they infect RED melodic phrase CELLS, again, multiplying asexually producing legion(p passingicate) cells. - The merozoites burst out of the exit blood cells every 48-72 hours, and as they release toxins in this process, this begins the symptoms. - The toxins cause hap attacks of shivering, fever, headaches, nausea, sweating and lethargy. The expiry of many red blood cells causes anaemia. - troops Response: At each stage of the parasites intent cycle, it produces a different pile of antigens (they stimulate the immune response). The host produces antibodies to stir up the pathogens, totally the antigens continually change, so the immune response is non effective. The merozoites in the colored escape detection Treatment: Natural immunity potful develop, but only 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 colorful cells). Some strains of plasmodium ar resistant however. Prevention: Protective clothing, bird louse 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 engineering science of mosquitoes to resist parasite.
