There is a common myth that it is something that only affects gay men. While gay men are disproportionately affected, the majority of new diagnoses in the UK are in the heterosexual population and a third of all HIV diagnoses are in women.
Coming into contact with an infected person will not lead to oneself putting at risk of HIV. HIV is carried in blood, semen, vaginal secretions and breast milk. One cannot catch HIV by sharing a toothbrush or through coming in into contact with someone’s saliva, e.g. by sharing a glass.
A person who knows his or her HIV positive status and is on medication is less likely to be able to pass on the infection than someone who is HIV positive and is unaware of his or her status. Being on treatment reduces the viral load and makes people less infectious.
