Our family has had 4 rounds (all 4 of us treated at the same time) of strep since November. (culture was done and was positive after 2 -4 days each time). We are friends with two other families that are going through the same thing. The last round of strep, all 3 families were on antibiotics simultaneously. We have wiped down surfaces in the house, but I was told that we aren't contagious after being on antibiotics for 24 hours and that the strep bacteria only lives on surfaces for 48 hours. So I have not changed the bedding in our home. We live in a very dry climate. Can our bedding be infecting us? Also could our pet be a carrier of strep and be causing this?
