Study Notes
Communicable Diseases (3.1.1)
- Pathogens are microorganisms causing infectious diseases.
- Include viruses, bacteria, protists, and fungi.
- Spread through direct contact, water, or air.
Viruses (3.1.1.1)
- Very small
- Invade cells and use their mechanisms to replicate.
- Cell bursting releases virus copies.
- Cell damage causes illness.
Bacteria (3.1.1.2)
- Small
- Multiply rapidly through binary fission.
- Produce toxins damaging cells.
Protists (3.1.1.3)
- Some are parasitic, residing inside hosts.
- Cause damage within the host.
Fungi (3.1.1.4)
- Can be single-celled or have thread-like structures (hyphae).
- Reproduce through spores.
- Some are parasitic.
Spread of Pathogens (3.1.1)
- Direct contact: Contaminated surfaces, bodily fluids, direct skin contact.
- Water: Contaminated water.
- Air: Droplet infection: Pathogens carried in droplets released during sneezing, coughing, or talking.
Reducing Spread of Pathogens (3.1.1)
- Improve hygiene (handwashing, disinfectants).
- Isolate raw meat.
- Avoid contact with infected individuals.
- Using tissues and handkerchiefs when sneezing
- Use pesticides to control vectors (animals that carry pathogens)
Viral Diseases (3.1.2)
- Viruses are highly dangerous, as they infect various cell types.
- Current lacks of cures.
Measles (3.1.2.1)
- Symptoms: Fever, red rash, potentially leading to pneumonia, encephalitis, and blindness.
- Spread through droplet infection.
