""Merie Symonds, head of sexual health at the Trust, said: 'Approximately a third of people in the UK who are HIV positive are currently unaware of their condition.""

There you go again!

How in hell does she know how many people, as yet untested, have the HIV virus, let alone what percentage of the total HIV positive population they represent.

Unless she has found a way of scanning the untested population of the UK, she can only be making a wild guess which cannot be supported by hard scientific evidence.

Statistical analysis only works if you have certain basic facts. She does not!
