    Ebola, HIV/AIDS, Pertussis, Measles
    Ebola, HIV/AIDS, Pertussis, and Measles
    Explanation
    The correct answer is "Ebola, HIV/AIDS, Pertussis, and Measles." These diseases are considered communicable because they can be transmitted from one person to another through various means such as direct contact, respiratory droplets, or sexual contact. They are caused by infectious agents such as viruses or bacteria, and can spread easily in populations, leading to outbreaks or epidemics if not properly controlled.

    Rate this question:

  • 10. 

    A disease carried from animal ------> human is an example of a communicable disease 

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A disease carried from animals to humans is known as a zoonotic disease. Zoonotic diseases can be transmitted through direct contact with infected animals, consumption of contaminated food or water, or exposure to contaminated environments. Examples of zoonotic diseases include rabies, Ebola, and avian influenza. These diseases can easily spread from animals to humans, making them communicable. Therefore, the given statement "A disease carried from animal to human is an example of a communicable disease" is true.

      Epidemic

    • C.

      Pandemic

    • D.

      Transdemic

    Correct Answer
    B. Epidemic
    Explanation
    An epidemic refers to the occurrence of cases of an illness or health-related events in a community or region that exceed the normal expectation. The term "epidemic" is used when the cases occur within a specific community or region and during a specific time period. It is a localized outbreak of a disease that spreads rapidly and affects a large number of people within a defined area. In contrast, an endemic refers to the constant presence of a disease within a specific population or geographic area, while a pandemic refers to a global outbreak of a disease. "Transdemic" is not a recognized term in the context of health-related events.

    • A.

      Epidemic

    • B.

      Pandemic

    • C.

      Endemic

    • D.

      Hyper Epidemic

    Correct Answer
    B. Pandemic
    Explanation
    A pandemic is an epidemic that affects a large part of the world or an entire country. It is a widespread outbreak of a disease that affects a significant number of people across different regions. This term is used when a disease spreads beyond national borders and reaches a global scale. Unlike an epidemic, which is more localized, a pandemic has a much broader impact and requires international cooperation and measures to control and mitigate its effects.

    Rate this question:

  • 21. 

    _________ disease is a disease that is prevalent in a population in a certain area for a long period of time

    • A.

      Endemic

    • B.

      Epidemic

    • C.

      Pandemic

    Correct Answer
    A. Endemic
    Explanation
    Endemic disease refers to a disease that is constantly present in a particular population or geographic area. It is characterized by a steady, ongoing occurrence of cases within that population over an extended period of time. Unlike epidemic or pandemic diseases, which involve a sudden increase in the number of cases, an endemic disease is more localized and does not spread rapidly to other areas. Therefore, the given correct answer, "Endemic," accurately describes a disease that is prevalent in a population in a certain area for a long period of time.

    Rate this question:

  • 22. 

    The inherent or acquired immune resistance offered by populations to the prevalence of a disease in a community is referred to as _________

  • 26. 

    Wound and inhalation transmissions are examples of "direct" transmitted diseases

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Wound and inhalation transmissions are considered "direct" transmitted diseases because they involve direct contact or exposure to the infectious agent. In the case of wound transmission, the disease-causing organism enters the body through a break in the skin, such as a cut or puncture. Inhalation transmission occurs when the infectious agent is inhaled into the respiratory system, often through respiratory droplets or airborne particles. Both modes of transmission involve direct contact with the source of the infection, making them examples of direct transmission.

    Rate this question:

  • 27. 

    Vectors such as air, water, and soil are examples of "indirect" disease transmission

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Vectors such as air, water, and soil can indirectly transmit diseases because they can carry and spread pathogens without direct contact between individuals. For example, contaminated water can spread waterborne diseases, and airborne pathogens can be inhaled and cause respiratory infections. Similarly, soil can carry parasites or bacteria that can infect individuals through contact or ingestion. Therefore, these vectors play a crucial role in the transmission of diseases indirectly.
