    Study Notes

    Pathogens

    • Pathogens are agents that cause diseases, capable of leading to illness or death.
    • Found in the air, food, and on various surfaces and individuals.

    Uncontrollable Risk Factors

    • Heredity: Family history and genetic traits influencing disease susceptibility.
    • Aging: Increased vulnerability to diseases with age.
    • Environmental Conditions: Poor hygiene, exposure to drugs, chemicals, and pollutants heighten risks.
    • Organism Resistance: Certain pathogens can resist bodily defenses and treatments.

    Controllable Risk Factors

    • Stress management is crucial for health.
    • Proper nutrition aids in preventing diseases.
    • Maintaining a high level of physical fitness contributes to immunity.
    • Sufficient sleep is vital for recovery and resilience.
    • Avoiding drug misuse is essential for minimizing health risks.
    • Good hygiene practices reduce infection risk.
    • Engaging in high-risk behaviors increases vulnerability to diseases.

    Routes of Pathogen Transmission

    • Direct Contact: Involves touch, kissing, and sexual relations.
    • Indirect Contact: Involves touching contaminated objects.
    • Airborne Contact: Inhalation of pathogens suspended in the air.
    • Food-borne Infection: Consumption of contaminated food.

    Additional Routes of Pathogen Transmission

    • Animal-borne Pathogens: Diseases spread via bites or contact with infected animals.
    • Water-borne Diseases: Contamination from drinking or swimming in polluted water.
    • Perinatal Transmission: Diseases passed from mother to infant during pregnancy or childbirth.

    Bacteria

    • Bacteria are single-celled organisms, with around 100 species harmful to humans.
    • Typically, diseases are caused by bacterial toxins rather than the bacteria themselves.
    • Bacteria can be observed using standard microscopes.

    Bacterial Diseases

    • Staphylococcal Infections: Typically reside on skin; can cause acne and other skin infections when skin is broken.
    • Streptococcal Infections: Known for causing strep throat and scarlet fever.
    • Pneumonia: Bacterial form shows symptoms such as chronic cough and chest pain.
    • Legionnaire’s Disease: Similar to pneumonia, water-borne with severe symptoms.
    • Tuberculosis (TB): Airborne disease causing lung inflammation leading to severe symptoms.

    Viruses

    • Viruses are minute microbes requiring host cells for replication and survival.
    • More than 150 viruses can cause human diseases and are resistant to various treatments.

    Viral Diseases

    • Common Cold: Over 200 viruses implicated; susceptibility increases with stress and allergies.
    • Influenza (Flu): Symptoms may vary; can be severe in vulnerable populations.
    • Mononucleosis: Symptoms include fatigue and sore throat; spread through body fluids, not easily contracted through casual contact.
    • Hepatitis: Causes liver inflammation, with symptoms varying by type (A, B, C).
      • Hepatitis A: Contracted via contaminated food or water.
      • Hepatitis B: Spread through body fluids, often associated with unprotected sex.
      • Hepatitis C: Linked to needle sharing; can lead to chronic liver issues.
    • Measles: Characterized by rash and high fever; significant long-term complications possible.

    Other Pathogens

    • Fungi: Can be beneficial (e.g., mushrooms), but some cause infections like candidiasis and athlete’s foot.
    • Protozoa: Single-celled organisms causing diseases, including trichomoniasis and malaria through mosquito bites.
    • Parasitic Worms: Infestations from raw fish; cooking can eliminate these risks.

    The Immune System

    • Functions to protect against harmful substances; antigens trigger immune responses.
    • Upon encountering antigens, the body produces antibodies to fight off invaders.

    Vaccines

    • Vaccination involves injecting a weakened form of pathogens to stimulate long-lasting immunity through antibody production.

    Noninfectious Diseases

    • Not caused by pathogens and cannot be transmitted through personal contact.
    • Often linked to lifestyle choices or poor hygiene.

    Chronic Lung Disease

    • Dyspnea: chronic breathlessness affecting daily activities and sleep.
    • Chronic Obstructive Pulmonary Disease (COPD) encompasses asthma, emphysema, and chronic bronchitis.

    Allergic Reactions

    • Hypersensitive immune response to specific antigens or allergens, with increased severity over time from exposure.

    Hay Fever

    • Seasonal respiratory disorder, prevalent during ragweed and flower blooming.
    • Symptoms: sneezing, itchy eyes/nose. Family history is common.
    • Relief options include injections and antihistamines.

    Asthma

    • Disease presenting with wheezing, shortness of breath, and coughing.
    • Triggers: air pollutants, allergens, and stress.
    • Management includes avoiding triggers and using medications.

    Emphysema

    • Gradual destruction of lung alveoli, leading to reduced lung function.
    • Strong association with smoking and air pollution; inadequate oxygen can lead to health complications.

    Bronchitis

    • Inflammation of bronchial tube lining, reducing airflow and causing mucus production.
    • Caused primarily by smoking, air pollution, and industrial exposure.

    Headaches

    • Symptoms: sensitivity to light/sound, nausea, throbbing.
    • Types include:
      • Tension Headaches: caused by muscle tension.
      • Migraines: marked by localized pain, often behind one eye.
      • Secondary Headaches: result from other health conditions.

    Seizures

    • Epilepsy: neurological disorder resulting from abnormal brain activity, leading to altered consciousness or convulsions.

    Premenstrual Syndrome (PMS)

    • Physical and emotional symptoms before menstruation, such as irritability, headaches, and bloating.
    • Management includes hormonal therapy, pain medications, and lifestyle adjustments.

    Endometriosis

    • Endometrial tissue grows outside the uterus, causing cramping, irregular periods, and potential infertility.

    Diabetes

    • Condition resulting from insufficient insulin production or utilization.
    • Symptoms: elevated blood sugar, thirst, frequent urination, slow healing.
    • Management involves insulin, dietary control, and exercise.

    Lactose Intolerance
