2.6.1 Communicable Diseases

• Direct contact is a transmission mode where pathogens are transferred through physical contact like touching or kissing.

  True
• Match the transmission mode with its description:

  Direct Contact ↔️ Pathogens transfer through physical contact

  Indirect Contact ↔️ Pathogens spread via contaminated surfaces

  Airborne ↔️ Pathogens travel through the air

  Vector-borne ↔️ Pathogens are carried by intermediate organisms
• Influenza is caused by a virus
• Name the four main types of pathogens that cause communicable diseases.

  Bacteria, viruses, fungi, protozoa
• What are some typical symptoms caused by bacterial pathogens?

  Fever, cough, fatigue
• What is the primary effect of protozoa on the body?

  Red blood cell destruction
• Protozoa can be transmitted through vectors like mosquitoes.


  True
• Direct contact involves pathogens spreading through physical contact, such as touching or kissing.


  True
• Vector-borne transmission requires an intermediate organism, such as a mosquito.


  True
• Match the pathogen type with a typical symptom:

  Bacteria ↔️ Fever

  Viruses ↔️ Body aches

  Fungi ↔️ Itching

  Protozoa ↔️ Chills
• Match the pathogen type with its effect on the body:

  Bacteria ↔️ Toxin production

  Viruses ↔️ Organ failure

  Fungi ↔️ Respiratory problems

  Protozoa ↔️ Red blood cell destruction
• Order the following control measures based on their primary goal:

  1️⃣ Hygiene

  2️⃣ Vaccination

  3️⃣ Treatment
• Vaccines use weakened or inactivated pathogens to stimulate antibody production without causing full-blown disease.

  True
• Vaccines are highly effective in preventing the spread of communicable diseases by stimulating the immune system.


  True
• Communicable diseases can be transmitted or passed on from one organism
• Airborne transmission occurs when pathogens are spread through the air
• Tuberculosis is caused by bacteria and transmitted through airborne means.


  True
• Order the transmission modes of communicable diseases:

  1️⃣ Direct Contact

  2️⃣ Indirect Contact

  3️⃣ Airborne

  4️⃣ Vector-borne
• Influenza is transmitted through the air
• Fungal pathogens often cause skin and nail infections
• Bacteria can transmit communicable diseases through airborne transmission.

  True
• Order the following transmission modes based on the type of contact involved:

  1️⃣ Direct Contact

  2️⃣ Indirect Contact

  3️⃣ Airborne

  4️⃣ Vector-borne
• Match the transmission mode with an example disease:

  Direct Contact ↔️ HIV

  Indirect Contact ↔️ Salmonella

  Airborne ↔️ Influenza

  Vector-borne ↔️ Malaria
• Bacterial infections often cause symptoms like fever, cough, and fatigue.


  True
• Fungal infections like athlete's foot primarily affect the skin and nails.


  True
• Frequent handwashing with soap and water is a key hygiene practice to prevent communicable diseases.

  True
• The immune system produces antibodies, which are proteins that recognize and bind to specific parts of a pathogen
• Antivirals block viral replication
• What are communicable diseases?

  Diseases that can be transmitted
• How does indirect contact transmit pathogens?

  Via contaminated surfaces
• What are pathogens?

  Disease-causing microorganisms
• What type of pathogen causes malaria?

  Protozoa
• HIV is transmitted through direct contact.


  True
• Viruses can cause organ failure in the body.


  True
• Pathogens are disease-causing microorganisms
• Transmission mechanisms are how communicable diseases spread from one person to another via different modes
• Pathogens spread through the air via airborne transmission from coughing or sneezing
• The symptoms and effects of communicable diseases vary depending on the type of pathogen
• Viral infections commonly cause fever, body aches, and immune system disruption
• Vaccines help the body build immunity against specific pathogens
