Includes

  Acquired immunodeficiency syndrome (AIDS)

### Scenarios

Affected individual

Obligatory

  Must not donate.

See if relevant

  Blood safety

Additional information

  HIV infection can destroy the immune system and lead to AIDS. It is known to be transmitted by transfusion. In the early stages of infection, the testing used by the Blood Services may not detect the virus allowing it to be passed on by transfusion.

Current or former sexual partner of an affected individual

Obligatory

  Must not donate if:

  Less than 3 months from the last sexual contact.

See if relevant

  Blood safety

Additional information

  HIV infection can be spread through sexual activity, including oral and anal sex. It may however not be transmitted for a long time into a relationship. This could be because the infection becomes more active in the infected partner, the uninfected partner acquires another infection or injury to a mucous membrane, or there is a change in the use of, or failure of, barrier contraceptives (e.g. condoms etc). In the early stages of infection, the testing used by the Blood Services may not detect the virus allowing it to be passed on by transfusion.

  Waiting 3 months from the last sexual contact will ensure that any infection is picked up by the tests used by the Blood Services.

Person currently or formerly sharing a home with an affected individual

Discretionary

  Accept.

See if relevant
  - Current or former sexual partner of affected individual above
Additional information

  HIV is neither contagious nor spread by the faecal-oral route. It is usually only spread through a direct blood to blood or sexual route. For these reasons, household contacts do not need to be deferred.
