Number of reported cases At least 7 How do we calculate the number of cases


Scotland uses a common law offence known as ‘Culpable and Reckless Conduct’ to prosecute reckless ‘exposure’ and transmission of sexually transmitted infections (STIs).

Guidelines from the Crown Office and Procurator Fiscal Service (COPFS) notes refers to a 1936 ruling which created the Scottish legal definition of recklessness as conduct that is ‘gross or wicked, or criminal negligence, something amounting, or at any rate analogous, to a criminal indifference to consequences’.

Unlike in England and Wales, there is no disclosure defence: consent on the part of the complainant to the conduct, even if instigated by them, is not a defence in cases of criminal transmission of infection.

‘Culpable and Reckless Conduct’ requires that there must be injury or danger of injury to another, but there is no requirement to prove specific intent to cause injury. If there is evidence that a person intentionally sets out to transmit HIV (or another STI) to another person, assault laws could be used to prosecute them.

There have been five known sexual ‘exposure’/transmission cases since the first successful prosecution in 2001. One case involved both HIV and hepatitis C transmission.

In addition to the above cases where all defendants were men, one woman has been prosecuted for exposing others to HIV via a needle prick (in 2016), and another woman was charged for Culpable and Reckless Conduct for allegedly spitting at another woman. HIV has also been considered relevant to an assault and robbery charge after a woman claiming to have HIV brandished a needle at a young woman before robbing her.

In June 2020, Police Scotland announced it had amended policy and practice by ceasing logging people living with HIV as ‘contagious’ in its intelligence database (a resource routinely used by police), and would remove existing entries. This step forward in policing would not have occurred without the intervention of HIV Scotland who brought the matter to the attention of HIV Scotland’s senior administration, who then confirmed the practice was outdated and not in-line with other policing policy.
