For many people, travel is an important aspect of life. Some choose to benefit from the positive quality-of-life effects which come from participating in leisure travel. Others have to stay in foreign countries for long periods due to personal or professional reasons. It is important to know what your rights are and also if you might be faced with difficulty entering another country due to an HIV+ status.
The second large study to look at whether people with HIV become non-infectious if they are on antiretroviral therapy (ART) has found no cases where someone with a viral load under 200 copies/ml transmitted HIV, either by anal or vaginal sex.
Statistical analysis shows that the maximum likely chance of transmission via anal sex from someone on successful HIV treatment was 1% a year for any anal sex and 4% for anal sex with ejaculation where the HIV-negative partner was receptive; but the true likelihood is probably much nearer to zero than this.
When asked what the study tells us about the chance of someone with an undetectable viral load transmitting HIV, presenter Alison Rodger said: "Our best estimate is it's zero."
