I'm going to try to keep my family free of hepatitis C.
That's kind of you but why are you so concerned about hepatitis C?
It contains worms and insects I want to avoid
Hepatitis C is a serious health condition and can lead to chronic problems like liver failure and even death. It's good that you want to keep your family free of hepatitis C since it shows that you care about their health and well-being. Since there isn't a vaccine for hepatitis C, it's extremely important to be safe and prevent your family from being infected.
I don't want anyone with worms as a family member.
Just because someone gets worms doesn't mean they're less of a family member. Still, its good to do what you can to protect and keep them safe.
