Document Summary
Life expectancy now approximately 80 years (higher for females) From control of infectious diseases (now leveling off) William stewart fail: antibiotic resistance has caused the problem to become worse. Number one being pneumonia and lower respiratory infections. Low income where many people die much younger (40%) Prions as an extra class so different. Must be able to control itself to minimize the damage it can do to the host. Neutrophil video: neutrophil actively follows pathogen like staph. Video: looks for virus cells and can decide which cells are infected with a virus. Multiple effects due to the overlap of different effectors (interaction effects) Things are not black and white, immunology studies still in progress. Not increasing or decreasing but it"s always there. Must have continuous new hosts or everyone just develops immunity to it and it dies out. Scenarios for if a population is infected by a new infections agent. Not useful as this basically kills all of its hosts.
