6.3.1 Communicable Diseases

• Communicable diseases can be transmitted through direct contact, indirect contact, airborne transmission, and vector-borne transmission
• What are the four main modes of transmission for communicable diseases?

  Direct, indirect, airborne, vector
• The distinction between communicable and non-communicable diseases is crucial for implementing prevention measures


  True
• Non-communicable diseases cannot be transmitted and are caused by a combination of genetic, physiological, environmental, and behavioral factors
• The transmission of communicable diseases occurs through several key modes
• HIV/AIDS is caused by the Human Immunodeficiency Virus
• What are the four main modes of transmission for communicable diseases?

  Direct, indirect, airborne, vector-borne
• Direct contact involves touching an infected person or their bodily fluids.


  True
• HIV is transmitted through direct contact with blood or bodily fluids
• How is malaria transmitted?

  Vector-borne (mosquitoes)
• How does vaccination build immunity to diseases?

  Exposing the body to weakened pathogens
• What is the primary benefit of hygiene practices in preventing communicable diseases?

  Reduces pathogen spread
• Order the following modes of transmission of communicable diseases based on their descriptions:

  1️⃣ Touching an infected person or their bodily fluids (Direct contact)

  2️⃣ Touching a contaminated surface or object (Indirect contact)

  3️⃣ Breathing in droplets or aerosols containing the pathogen (Airborne transmission)

  4️⃣ Transmitted by an infected organism like a mosquito or tick (Vector-borne transmission)
• Non-communicable diseases cannot be transmitted between people and are caused by genetic, physiological, environmental, and behavioral factors
• What is airborne transmission of communicable diseases?

  Breathing in infected droplets
• Understanding the distinction between communicable and non-communicable diseases is crucial for implementing appropriate prevention and control measures


  True
• Match the mode of transmission with its description:

  Direct contact ↔️ Touching an infected person or their bodily fluids

  Indirect contact ↔️ Touching a contaminated surface or object

  Airborne transmission ↔️ Breathing in droplets or aerosols

  Vector-borne transmission ↔️ Transmitted by infected organisms
• What type of organism transmits malaria?

  Mosquitoes
• Non-communicable diseases cannot be transmitted between people
• Which pathogen causes influenza?

  Influenza virus
• What are the main symptoms of tuberculosis?

  Persistent cough, weight loss
• Understanding pathogens, transmission, and symptoms is crucial for prevention.


  True
• Herd immunity occurs when a high percentage of a population is vaccinated.

  True
• Social distancing is a public health measure to minimize close contact
• Antibodies and immune cells work to neutralize and eliminate the pathogen
• What are communicable diseases?

  Diseases transmitted between people
• Understanding how communicable diseases spread is crucial for preventing their transmission


  True
• Match the characteristic with the correct type of disease:

  Transmission ↔️ Can be transmitted from person to person for communicable diseases ||| Cannot be transmitted between people for non-communicable diseases

  Causes ↔️ Caused by pathogens for communicable diseases ||| Caused by genetic, lifestyle, and environmental factors for non-communicable diseases

  Examples ↔️ Influenza, HIV/AIDS, Tuberculosis for communicable diseases ||| Cancer, Diabetes, Cardiovascular Diseases for non-communicable diseases
• What is vector-borne transmission of communicable diseases?

  Transmitted by infected organisms
• Why is understanding the distinction between communicable and non-communicable diseases crucial?

  For prevention and control
• Indirect contact involves touching a contaminated surface or object.


  True
• Communicable diseases can be passed on from one person to another.


  True
• What are the primary causes of non-communicable diseases?

  Genetic, lifestyle, environmental factors
• What is the pathogen responsible for influenza?

  Influenza virus
• Cholera is caused by the pathogen Vibrio cholerae
• Hand washing is a key hygiene practice to prevent diseases like influenza and cholera
• Steps involved in environmental control to prevent communicable diseases

  1️⃣ Ensure access to clean water

  2️⃣ Proper waste disposal

  3️⃣ Effective pest management
• The immune system identifies and eliminates pathogens in the body.


  True
• A strong immune system depends on factors like good health and hygiene.


  True
• What is the role of white blood cells in the immune system?

  Recognizing and attacking pathogens
