Answer by Josiah Tay:
Best way is to take a reliable HIV test. You can’t tell from just looking. There is a chance that a person knows he is HIV positive, but he does not wish to reveal it to you. Some HIV carriers who have undergone drug treatment have very low levels of the virus such that current HIV tests cannot detect them though. However, even if tests cannot detect it, that does not mean that the person is HIV-free. There are even cases of people who claim to have been cured of HIV, and who have been tested negative for years, suddenly become positive again. HIV is a nasty virus which can hide in all corners of your body and then come out again. It is best to avoid getting HIV in the first place. So better to be safe and sorry. If you have any doubts, just get tested to ease your mind and free yourself from worry.
