With efforts to reduce the number of new HIV, hepatitis C and sexually transmitted infections focused on getting at-risk groups tested, the Testing Week Scotland campaign is asking people to #KnowYourRisk.
Testing Week Scotland, which runs from 11-17 September 2017, is raising awareness of the different ways that the infections can be passed on so that people can judge whether they have been at risk.
It aims to send the message that once you #KnowYourRisk, you can do something about it.
