A third of Scottish adults would be uncomfortable giving first aid to someone receiving treatment for HIV, according to a new survey.

Research for the Terrence Higgins Trust also found a similar number would feel uncomfortable dating someone being treated for the virus, while a quarter felt the same way about playing contact sport.

And just 7% of Scots knew that people living with HIV and who are on effective treatment cannot pass on the virus.

The charity said the findings showed outdated beliefs about HIV transmission are fuelling stigma and discrimination, which can prevent people coming forward for testing.

It comes as the trust launches a new campaign, Can't Pass It On, which aims to tackle misconceptions and encourage people to get tested.

Robert McKay, the charity's director in Scotland, said: "It is saddening to see that, in 2017, people in Scotland are still being treated differently because of their HIV status.

"These fears are unfounded, because we can say, with confidence, that people who are on effective treatment can't transmit HIV, they are not infectious. There is no reason they can't date, fall in love, have a healthy sex life, work or have families just like anyone else.

"We urgently need to bring people up to date with medical evidence and listen to science, not stigma."

According to the trust, one in seven people living with HIV does not know they have it. This means they are not getting treatment and can still pass on the virus.

Michael Nugent, 33, from Glasgow, said he did not know a lot about HIV when he was diagnosed in 2016.

He said: "I literally thought I had ten years to live. I was also really worried about my family and friends and didn't want to be near my nieces and nephews. I was worried I could infect them if I cut my finger.

"Now I know that HIV is not a death sentence. Now I'm on medication I feel in control of my HIV and much more relaxed."

He continued: "HIV medication not only helps you physically be well, but also helps psychologically. I know that by taking my tablets I'm uninfectious. I can't pass on the virus. I felt it the first time I was given my prescription, the power from it, the fact I am now in control."
