  6. The average person has less than 10 micrograms per deciliter, or 100 parts per billion, ppb, of lead in their blood serum. Symptoms show up when you’ve got 100ppb Higher than 200 ppb unusual Cause your not quite evil enough.

  14. 7. Based on the information presented, does the lead poisoning in this community show a high morbidity? A high mortality? A high prevalence? A high incidence? Morbidity: Prevalence of disease. Yes, of course it will depend on the population Mortality: Death rate from disease: Low Prevalence: # of people with disease at a given span of time. Yes. Incidence: # of new cases over a given time period: High

  15. Would you consider the lead poisoning in this case an epidemic? Epidemic: High incidence. Above normal expectations. Yes this is an epidemic

  16. Signs: Objective visual indication of disease Salivation Personality change RBC Lead in urine Intelligence? Vision? Symptom: Subjective feeling only know to patient Joint pain Difficulty walking? Can a sign be faked? 9. Identify as signs or symptoms
