10% of people think spitting transmits HIV
A new survey suggests that 1 in 5 people don't know how HIV is spread between men and women.
The National Aids Trust, which conducted the research, believes it's crucial for people to understand the basics in order to protect themselves.
The report also reveals that 1 in 10 people think the disease can be spread through kissing and spitting, which is untrue.
Chief Executive of the trust, Deborah Jack, speaks to BBC Radio 5 live Breakfast's Phil Williams about the research.
