Venereal disease
Condyloma does not prevent blood donation.
The first symptomatic period of herpes on the mucosae of the genitals prevents blood donation for four months. Symptomatic periods that occur later on prevent donation for two weeks if the symptoms are severe and antibiotics are needed for their treatment. However, if the symptoms are mild, blood can be donated when the blistering phase has passed and the blisters have dried.
Chlamydia and gonorrhoea cause a four-month long obstacle to donation. Syphilis prevents donation. Also an old scar visible in blood tests after healed and treated syphilis prevents donation.
