    Study Notes

    Virus-Caused Diseases

    • Viruses cause a large number of diseases affecting animals, but not plants
    • Viruses reproduce inside cells, destroying them
    • Viruses reproduce rapidly in the human body
    • Antibiotics are ineffective on viruses
    • Pain killers treat symptoms, not causes of viral diseases
    • Examples of viral diseases include measles and HIV

    Measles

    • Measles is a viral infection
    • Characterized by a high fever and red rash
    • Can be fatal.
    • Spread by airborne droplets (coughs and sneezes)
    • Symptoms can be treated with painkillers
    • Measles is preventable by vaccination
    • Vaccination has dramatically reduced measles cases globally

    HIV

    • HIV is a virus
    • A communicable disease
    • Spread by sexual contact or exchange of bodily fluids like blood
    • Symptoms include a weakened immune system, fever, and sometimes a red skin rash.
    • Can lead to AIDS
    • Not treatable by antibiotics
    • Treatment focuses on managing symptoms and preventing complications

    Other Viral Diseases

    • Specific viruses cause specific diseases, each with unique characteristics
    • Examples include various specific diseases (e.g., Tobacco Mosaic Virus)
    • Viral infections are often mild and treatable with supportive care

    Pathogens and Diseases

    • Pathogens are microorganisms that cause infectious disease
    • Examples of pathogens include bacteria, viruses, fungi, and protists. Disease can be communicable (infectious) or non-communicable
    • Viruses reproduce rapidly inside cells, thereby destroying them.

    Defenses Against Infection

    • Humans have non-specific defenses that stop infection. Mucus traps pathogens and cilia move mucus out of the body
    • Human skin is a non-specific defense
    • Cilia and mucus in the trachea are a non-specific barrier against infection

    Communicable Diseases

    • Communicable diseases are transmitted between organisms by a pathogen
    • Pathogens can be various microbes (e.g., viruses, bacteria).

    Smoking and Specific Diseases

    • Smoking increases the risk of lung disease, cardiovascular disease, and cancer.

    Antibiotic Efficacy

    • Antibiotics are ineffective against viruses.

    Important Terminology

    • Pathogen: A microorganism that causes disease.
    • Communicable disease: A disease spread between organisms via a pathogen.
    • Non-specific defenses: Physical barriers such as skin and chemical barriers such as mucus.
    • Specific defenses: The immune system; made up of cells that fight infection.
