Stephen Fry has joined forces with national and international YouTube stars to encourage HIV testing, following the launch of the Terrence Higgins Trust's National HIV Testing Week.

Fry appears in a video highlighting the importance of HIV testing, and is supported by social media stars including Calum McSwiggan, Alex Bertie and Arielle Scarcella. McSwiggan commented 'Young people are often labelled as disinterested in social issues but this shows we care and want to use our influence to promote HIV testing and sexual health'.
