Sexually transmitted diseases
Also known as sexually transmitted infections (STIs). These are diseases or infections that are spread from individual to individual by unprotected sexual contact. This includes vaginal intercourse, anal intercourse and oral sex. Some examples of these are HIV, chlamydia, gonorrhoea, genital herpes and genital warts. Whilst some types show symptoms relatively soon after exposure to the disease, in some cases such as chlamydia, the affected person won't experience any symptoms and thus will make it easier for other people to be transmitted without their knowledge. On the other hand, infection by the virus herpes simplex will lead to "small, painful blisters or sores". for a short period of time. The virus will then lay dormant in the affected person until a trigger causes it to resurface and at the moment there is no definitive cure for genital herpes.
