My husband's brother used to live with us, but I had to ask him to move out about a year ago for reasons not pertaining to this post. Since then he moved in with his girlfriend, & her 7 year old daughter. The girlfriend is now pregnant and was diagnosed with HIV, he too tested positive. I don't know about the daughter as I haven't asked and am a little scared to know.
My husband and I have an appointment to get checked, but he thinks I am over reacting. I know the chances of us catching it just by living together is very small, but I worry that maybe he used one of my husbands razors.
My question is: How do I handle it when they come to visit? I have done some research and know how the virus is spread, but still worry about the exposure to my family. Especially because we don't know about the daughter yet and I have a toddler, cut's and scrapes are a way of life here.
