Study Notes
Unit 3: Humans and the Environment
- Lesson 9.2: Biological and social hazards
- Pollutants impact organisms, including humans, directly and indirectly.
Vocabulary
- Infectious disease
- Emerging disease
- Environmental Health
- Pathogen
- Hazard
Teacher Talk: Summary (Infectious Diseases)
- Infectious diseases are caused by pathogens (e.g., viruses, bacteria).
- Globally, infectious diseases are a leading cause of death (2016 data).
- Diseases like lower respiratory infections, diarrheal diseases, and tuberculosis are among the top 10 causes of death worldwide.
- Diseases can spread directly from person-to-person through various mechanisms (e.g., touching, bodily fluids, breathing in droplets).
- HIV (causing AIDS) transmits through infected blood and bodily fluids.
- Tuberculosis (TB) spreads via airborne droplets produced when an infected person coughs, sneezes, speaks, and spits.
Teacher Talk: Summary (The Swiss Cheese Model for Infectious Disease)
- Prevention strategies (e.g., vaccinations, handwashing, safe food handling, cleaning and disinfecting) can act as barriers to disease spread.
Explore (Questions and Guided Questions)
- Question 1: Write an essay on avoiding infectious diseases, including symptoms and prevention.
- Question 2: Provide examples of infectious diseases with devastating impacts.
- Question 3: Write an essay on the critical importance of clean water sources in reducing infectious disease.
Vocabulary (Emerging Diseases)
- Infectious disease
- Emerging disease
- Environmental Health
- Pathogen
- Hazard
Teacher Talk: Summary (Emerging Diseases)
- Emerging diseases are those that appear suddenly in human populations or spread rapidly, often due to lack of resistance or available vaccines.
- Factors contributing to emerging diseases include increased human mobility, antibiotic resistance, and environmental changes.
Teacher Talk: Summary (Increasing Mobility)
- Disease transmission can happen quickly when people and animals move across geographical areas carrying pathogens.
Teacher Talk: Summary (Antibiotic Resistance)
- Some diseases, like tuberculosis, are becoming resistant to antibiotics meaning that they can continue to survive and spread even in the presence of medication meant to eliminate them.
Teacher Talk: Summary (A Changing Environment)
- Alterations to environments (e.g., deforestation) can expose populations to pathogens previously isolated.
Vocabulary (Social Hazards)
- Infectious disease
- Emerging disease
- Environmental Health
- Pathogen
- Hazard
Teacher Talk: Summary (Social Hazards)
- Social hazards (e.g., smoking, exposure to harmful substances, working with harmful chemicals) impact populations.
Teacher Talk: Summary (Examples of Specific Social Hazards)
- Slips, trips, and falls
- Exposure to harmful substances
- Confined spaces
- Electricity
- Extreme temperatures
- Toxic materials
Explore (Questions and Performance Tasks)
- Questions on prioritizing actions and creating plans to manage and reduce the spread of infectious diseases. Include specific examples of immediate measures.
- Tasks of Health Coordinator
- Prioritizing issues and actions for substance abuse and mental health crises.
- Creating awareness plans for social hazards.
Elaborate (Connection to Real Life)
- Review the UAE's response to the COVID-19 outbreak for strengths and weaknesses.
