Answer:
yes!
Step-by-step explanation:
anytime a person is working with others in any capacity, you should do everything you can to prevent spreading illness.
in the medical field, you should be extremely cautious about this, and I would say that jane should also take precautions to prevent the elderly from getting sick.
the elderly typically have weaker immune systems and it is more strenuous for their bodies to recover from a cold than a person in their 20s. so even a minor cold for Jane could lead to serious complications in an older individual
I hope this helped :)
