Document Summary
Spread person to person: water droplet transmission. Symptoms: fever > 38. 0 c, cough, shortness of breath or difficulty breathing. Parasites: malaria is caused by a single-celles parasite called plasmodium, which is transmitted via the bites of infected mosquitoes. Prions-protein and infection: a protein in a misfolded form, no dna or rna, bovine spongiform encephalopathy (bse) (mad cow disease!!) Symptoms: abnormal behavior, loss of coordination, tremors, rigidity, irritability, and progressive dementia: death usually occurs within 3-12 months from the onset of symptoms. How do you catch an infection: animals and insects. Contact is generally from person to person for viruses and via persons, animals, plants, food, soil and water for bacteria: our immune system protects us somewhat from infection. Lymphatic system: vessels/glands that pick up fluid, protein, lipids, etc. Contain wbcs that trap and destroy and filter pathogens. Histamine causes blood vessels to dilate and fluid to accumulate.
