Herein, do you legally have to tell someone you have herpes?
There aren't any federal or state laws making it illegal for you to not tell a partner about an STD you may have. That being said, it is typically illegal, civilly and criminally, to knowingly or recklessly transmit an STD. Telling someone you have an STD is not the same obligation as knowingly transmitting an STD.
Additionally, is giving someone herpes a felony? It is also a crime in California to engage in unprotected sexual activity with someone else, knowing that you are infected with HIV. If you do so specifically to infect someone else with the disease, you commit a felony offense. (California Health and Safety Code section 120291.)
Similarly, you may ask, can you sue someone for knowingly giving you herpes?
Yes, you can file a personal injury lawsuit against someone who infected you with herpes. You can sue even if the sex was consensual. The lawsuit would claim that the transmitter was negligent. He or she could have prevented the transmission of their herpes, but failed to do so.
Can you sue someone for giving you herpes if they didn't know?
If a sexual partner had knowledge of his/her STD and infected you, he or she may be liable for damages in a civil lawsuit.
