No you can not tell by looking at a person.
It is hard to say whether any person carries HIV or AIDS by looking them. AIDS virus need to be identified from a person's blood by lab techniques. Only the medical report can confirm the presence or absence of an infection.
A person with AIDS looks like anybody else, a normal person. It is impossible to tell if someone is infected with AIDS just by looking at them. It has no outward signs that would let you know if a person has it. In later stages of AIDS, they may often take on a very sick, gaunt appearance, because of AIDS ravaging their body, but there would be no signs that they have any particular illness.
There are many misconceptions about the transmission of AIDS. Some are that AIDS can only infect homosexuals or drug users, that AIDS cannot be transmitted through oral sex, that you can tell if a person has AIDS by looking at them, and that AIDS can be spread by casual contact. All of these misconceptions are factually inaccurate.
