Question

question 61
a \parenteral infection\ is caused by:
droplet infection
fecal-oral transmission
a skin piercing entry
vaccination

Explanation:

Parenteral infection refers to infection through routes other than the digestive tract. A skin - piercing entry (like through needles, cuts etc.) allows pathogens to enter the body without going through the oral - fecal or respiratory (droplet) routes. Droplet infection is respiratory, fecal - oral is digestive, and vaccination is a controlled introduction (not an infection - causing entry in this context). So the cause is a skin piercing entry.

Answer:

C. a skin piercing entry (assuming the options are labeled A: droplet infection, B: fecal - oral transmission, C: a skin piercing entry, D: vaccination)
