    Study Notes

    Communicable Diseases

    • Communicable diseases spread from person to person, posing a significant threat to populations. Historical outbreaks caused major societal disruption and high death tolls.

    Historical Diseases

    • Bubonic Plague: A bacterial infection characterized by flu-like symptoms, swelling of lymph nodes (buboes), and potentially lung infection.
      • Historically widespread, especially in medieval England due to poor sanitation.
      • Spread through fleas carried by rodents.
      • Still exists today in some parts of the world.
    • Spanish Flu: A highly contagious influenza virus causing fever, chills, headache, sore throat, and cough.
      • Especially dangerous to young adults, children, elderly, and immune-compromised people.
      • 20-40 million deaths in 1918 alone, exceeding World War I casualties.

    Current Diseases

    • Swine Flu (H1N1): Influenza variant causing headache, exhaustion, fever, chills, and sore throat.
      • Significant global outbreak in 2009, infecting millions.
      • Estimated death toll far lower than Spanish flu due to improved medicine and sanitation.
    • HIV: A virus attacking the immune system's T-cells, leading to AIDS.
      • Transmitted through semen, vaginal fluids, and blood (e.g., unprotected sex, shared needles).
      • Symptoms can develop over years; frequent testing is critical for those at risk.
      • Millions infected globally, with significant burden in Africa.
    • Ebola: A hemorrhagic fever often deadly in humans.
      • Symptoms include fever, body aches, bleeding, and gastrointestinal issues.
      • Onset within two to ten days of exposure.
      • No vaccine but some antiviral treatments exist.
    • COVID-19: A disease caused by SARS-CoV2, spreading through respiratory droplets, infecting various organ systems potentially causing fatal outcomes.
      • Global pandemic in 2020.
      • Multiple preventative measures and vaccines are currently available.

    Prevention

    • Sanitation: Crucial for disease prevention. Handwashing (before eating, after restroom use, after handling waste) is vital, reducing diarrhea and respiratory illnesses. Safe sex practices and avoiding sharing needles important for specific diseases like HIV.
    • Vaccination: Using small doses of pathogens to stimulate the immune response.
      • Critical for preventing disease; smallpox vaccination is a success story.
      • Unfounded fears about vaccines causing autism pose a serious risk.
      • Vaccines protect individuals and prevent disease spreading across populations.
