Many people do not fully understand how HIV is transmitted and are putting their sexual health at risk as a result, a new survey has found.
Ipsos Mori researchers polled 1,981 over-16s and found that many did not realise the risks posed by unprotected sex.
Twenty-one per cent did not know that HIV can be transmitted between a man and a woman who don't use a condom, and 26 per cent did not realise it could be transmitted between two men.
The findings may go some way to explaining why 49 per cent of British people do not always use a condom with a new sexual partner.
Britons need "a wake-up call on condom use", according to Deborah Jack, chief executive of the National Aids Trust.
"Too many people don't know the basic facts on how condoms prevent a sexually transmitted infection such as HIV," she noted. "We need to educate the whole population in the importance of condoms."
