What are 3 examples of pathogens being spread by indirect transmission?
- Vectors (organisms that transfer from the pathogen host to another)
- Droplet infection (droplets of mucus that cant control the pathogen that need to be coughed/sneezed out)
- Waterborne and food ( the pathogen infects the water or food due to uncooked

It is a drug that fights off infections
11 of 20
What is the problem of handing out too many antibiotics?
Because the bacteria in your body can become immune to the antibiotic, therefore causing the immune antibiotic to multiply and become stronger.
