Describe a variety of infectious diseases caused by pathogens, including micro-organisms, macro-organisms and non-cellular pathogens, and collect primary and secondary sourced data and information relating to disease transmission, including:
Investigate modes of transmission of infectious diseases including direct contact, indirect contact and vector transmission
True or False (confer and decide)
Infectious diseases can be passed from one person to another.
Bacteria are living cells, while viruses are non-living.
Your skin is considered part of the first line of defence.
A vector is a type of medicine used to kill pathogens.
Antibiotics are used to treat viral infections like the flu.
Fungi are eukaryotic organisms that can be unicellular (like yeast) or multicellular (like mould).
Protozoa are non-living pathogens that require a host cell to "come alive."
Macroparasites are visible to the naked eye and can live outside the body (ectoparasites).
Tetanus is an infectious disease, but it is contagious because you can't "catch" it from another person.
True. (That is what makes them "infectious").
True. (Viruses require a host cell to replicate and aren't "alive" on their own).
True. (It acts as a physical barrier to stop pathogens from entering).
False. (A vector is a carrier, like a mosquito or tick, that spreads the disease).
False. (Antibiotics only work on bacteria; antivirals are used for viruses
6. True.
7. False. (Protozoa are unicellular eukaryotic organisms; they are very much alive. You're thinking of viruses).
8. True. (Examples include ticks, leeches, or lice).
9. True. (You get it from bacteria in soil entering a wound, not from a person sneezing on you).
