Study Notes
Preventive Medicine
- Preventing illness is crucial, as treatments can be expensive, ineffective, or non-existent.
- Understanding the causes of disease is critical for effective prevention.
Infectious Diseases
- Infectious diseases spread from person to person.
- They are caused by microbes, tiny living organisms invisible to the naked eye.
- Microbes exist in the air, soil, water, and in plants, animals, and humans.
- While many microbes are harmless, some are pathogenic (disease-causing).
- There are four main types of microbes: viruses, bacteria, protozoa, and fungi.
- When microbes enter the body, they multiply rapidly, causing disruptions and producing toxins.
Parasitic Worms
- Parasitic worms live on or inside a larger organism, obtaining nourishment from the host.
- Examples of parasitic worms affecting humans include threadworm, roundworm, ascaris, tapeworm, and hookworm.
- Some parasitic worms, such as threadworm, roundworm, and ascaris, are not typically serious.
- Tapeworm and hookworm infections are more concerning.
