I think this all depends about if you have kids and how old they are. My daughter is 2 1/2 and if there ond of the kids in her sunday school class is sick, they all get sick. If you have kids that don't know how to contain their germs, you should keep them home, even if they are well enought to make it through Church. The question shouldn't just be can I do this, but do you want to go get a bunch of other families sick. I always get annoyed if I go to pick my daughter up from her sunday school class and I can tell that another kid is sick. Because inevitable our whole family gets sick and I'll often end up missing a day of work, etc.
So if you have young germ spreading kids, I say keep them home if they show signs of being sick, not because they can't make it through the service, but for the sake of all the other families. I know some people think that they are die hard and are just being good Christians when they still come to church when their sick, but it's not always loving to your neighbor
If you don't have young kids it's a different story. Go if you feel like you aren't a germ threat and you like you can make it through the service.
