Hello,
Thank you for your post and apologies for the delay in giving you a reply.
I will answer each of your questions here below:
1.) Yes, it is.
2.) Highly unlikely. However that depends on the state of your immune system, and not your age.
3.) Yes, they do. Antibodies are always detected, as well as the virus (if not on anti-retroviral treatment).
4.) Not at all.
Best wishes,
Dr José
Is there a reason I have no reply?
