I understand your concern about potentially contracting herpes simplex virus type 2 (HSV-2) after having sexual contact with someone who has the infection. It's good that you got tested for HSV-2 a month after the exposure. A negative blood test result at that point suggests you may not have contracted the virus, but it's important to note a few things:

HSV-2 is a sexually transmitted infection that causes genital herpes. It can take up to 3-6 months after exposure for antibodies to be detected in a blood test. So while a negative result after 1 month is reassuring, it does not completely rule out a potential infection. Some people may not develop detectable antibodies for even longer.

My advice would be to get re-tested again in 3-6 months since your last exposure to confirm you did not contract HSV-2. In the meantime, avoid any sexual contact to prevent potentially spreading the virus if you were infected but it's not showing up on tests yet.

I would also suggest speaking to a healthcare provider about your specific situation and risks. They can provide personalized guidance based on your test results, symptoms if any, and sexual history. Managing genital herpes requires professional medical support.

Please don't hesitate to reach out for any other questions or concerns you may have. Your health and well-being are important, and I'm here to provide a supportive, understanding environment as you navigate this.
