Suffering from herpes

Q: I have unfortunately have been diagnosed with genital herpes and oral herpes. I read on websites that it can spread through the skin even if there is no sore or fluid. What should I do in terms of praying Salaah because I touch my face and then touch the carpet? How should my contact with people be and what happens if I spread the disease to others. Do I get a sin for that? What do I do to all the people that I had spread the disease to previously due to handshakes (if even the disease spreads that way), sharing food and other ways?
