Cates,
That depends on your abilities and if you have other situations in your life which make the ailment hard to do essential tasks for.
Few people with Hep C need a caregiver, but when liver damage gets severe enough, it can become helpful, and then necessary top have one.
For the vast majority of people with Hep C the answer to the question is not really. Because of the low treatment times, (8-12 weeks) the minimal side effects, and the efficacy of the new DAA treatments (96+%)
Hep C has become something that people can push past with little disruption to their life. I worked during my first four treatments, but once I was on disability, others were there to help me.
A support network is a better overall plan (not that it can't include a caregiver,) people around you who can help in circumstances, and can help share your burden with you.
I hope this helps
