Cold sores or genital herpes

Cold sores (oral herpes) and genital herpes can be a sign of both ARS and late-stage HIV infection.

And having herpes can also be a risk factor for contracting HIV. This is because genital herpes can cause ulcers that make it easier for HIV to enter the body during sex. And people who have HIV tend to have more severe herpes outbreaks more often because HIV weakens the immune system.
