<s>[INST] 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? [/INST] HINeither your bedding nor the pets would be culprits hereThe infections have just been passed around between the members of your family </s>
