Why no one in curezone ever sue for other's giving them Herpes?

USA is a nation with the most number of lawsuits, yet I am surprised when it comes to Herpes 2, all became so quiet. Why in people's court, people will sue even for $50. and not for Herpes 2? Why when I heard from counselor or pastor that if they found one is abused, they will report to the police directly, but not Herpes? Why cigarette company was sued, why those companies responsible for this episode will not be sue? This does not help in our healing, I am just curious at the spirit behind.
