- Consider that the Herd Immunity Threshold is dependent on the reproduction number for an infectious disease. The combination of herd immunity and quarantines were highly effective for eradicating smallpox. What is different about the symptoms of polio infection that makes quarantining infected individuals much more difficult?What host defense is illustrated in this figure? Multiple Choice: select one: Lacrimation; first line defenseComplement; second line defenseNatural killer cells; first line defenseInterferon; first line defenseInterferon; second line defenseWhich of your body’s nonspecific host defenses would help fight a pathogen entering your body through each of the following portals? (a) A small cut on your hand; (b) inhalation into your lungs; (c) ingestion with contaminated food.
- Which of the following involves pseudopods? adherence of phagocytes to pathogens chemotaxis opsonization extracellular killing a & bSmallpox has been widely reported as a possible bioterror weapon. Given what you know about the etiology of the disease and the current state of the world’s immunity to smallpox, discuss how effective (or ineffective) a smallpox weapon might be.
