Estimating the likelihood of recent HIV infection - Implications for criminal prosecution.

Friday 5th August 2011

Now in the UK anyone diagnosed HIV positive is also told on the basis of a 'RITA test' whether or not it is likely that they have been infected in the previous six months.

NAT publishes has published a new report: 'HIV Forensics II: Estimating the likelihood of recent HIV infection - implications for criminal prosecution'. Now in the UK anyone diagnosed HIV positive is also told on the basis of a 'RITA test' whether or not it is likely that they have been infected in the previous six months. NAT was concerned that these RITA test results might be misunderstood or misused to claim that one can know for sure that someone was responsible for passing on HIV to someone else (for example by being their only sexual partner in the last six months). The report shows that the tests are not reliable at the individual level to make such judgements confidently and the test results should be interpreted with caution in a court of law.
