Communicable disease (infectious): • Can be transmitted from an infected person, animal, or

object to another personNoncommunicable disease: • Non-transmissible (can’t be “caught”)Chronic disease: • Lasts longer than 3 months, sometimes for the

remainder of one’s lifeAcute disease: • Peak severity of symptoms occurs and subsides within

3 months of onset, usually within days or weeks 1 min.

Review: • Which are:

- Communicable (Infectious)- Noncommunicable- Chronic- Acute

Our Goal Today:

Analyze the history of human health in terms of:

- major epidemics- beliefs about health- medical discoveries- causes of death- life expectancy

Detail or Conclusion?

1) Caused by fleas and rats2) 1939 doctor discovered the cure for the

plague3) Spread fast throughout the world4) Better sanitation has reduced many

infectious diseases (including cholera)

Review: Conclusions/Patterns• Life expectancy:

– Increased by more than 30 years in 20th century (47 to 78)– Why?

• Leading causes of death: – communicable (infectious) to noncommunicable (chronic) shift began in 1920’s– Why?

• Medical discoveries:– Antibiotics, vaccines, diagnostic & treatment tools– Why?

• Beliefs about illness: Divine intervention—people were being punished for their sins then… Miasmas theory: diseases spread by miasmas or “bad air”then… Germ theory: diseases cause by microorganisms

– Why?

• Epidemics:– History of uncertain explanations of origin and patterns– Scientists began collecting & analyzing data Up to 5 min.

Answer the following questions independently in notebooks (6).

1. MAJOR EPIDEMICS: Why are there fewer deadly epidemics today than in the past? (list 3 reasons)

2. LIFE EXPECTANCY: During which time period was there the largest increase in average life expectancy in the US?

3. CAUSES OF DEATH: Why was there such a big increase in average life expectancy during this time period in the US?

4. BELIEFS ABOUT HEALTH: If a person contracted a disease and died in the Middle Ages, how might the explanation of what happened be different than it would be today?

5. MEDICAL DISCOVERIES: Why do you think smallpox has been eradicated (eliminated from the world completely), while tuberculosis has not? Give at least 1 reason.
