Question

a. she shared a dirty needle when injecting drugs with an acquaintance.
b. she didn’t thoroughly wash her hands after using the restroom.
c. she consumed food that wasn’t cooked to a safe temperature.
d. she inhaled droplets from a nearby stranger’s cough.

Answer 1

The most likely cause of Anna's poliovirus infection is:

b. she didn’t thoroughly wash her hands after using the restroom.

Poliovirus is primarily transmitted through the fecal-oral route, which can occur if proper hand hygiene is not practiced after using the restroom. It is less commonly spread through contaminated food or water (option c) but is not transmitted through droplets from coughs (option d). Sharing a dirty needle (option a) is not a typical transmission route for poliovirus.
