§ Mr. Butterfill
asked the Secretary of State for Social Services whether he has received any evidence which suggests that the acquired immune deficiency syndrome virus HTLV-III may be transmissible through saliva; and if he will make a statement.
§ Mr. Kenneth Clarke
There is limited scientific evidence to show that the AIDS associated virus526W (HTLVIII) can be transmitted in saliva. However, epidemiological evidence indicates that AIDS is usually transmitted through sexual contact (predominantly homosexual intercourse), sharing unclean intravenous needles or through transfusion of AIDS infected blood or blood products.
