HIV+ with undetectable virus are ‘non-infectious’: Swiss experts
Posted in virus on 31 January 2008 at 18:04.
A panel of Swiss HIV experts have declared that HIV-positive people with undetectable viral load are sexually non-infectious. This is the first time that medical experts anywhere have agreed that well-suppressed blood viral levels are a reliable measure of sexual infectivity. This will be controversial, but it’s a fascinating development.

The statement’s headline statement says that “after review of the medical literature and extensive discussion,” the Swiss Federal Commission for HIV / AIDS resolves that, “An HIV-infected person on antiretroviral therapy with completely suppressed viraemia (“effective ART”) is not sexually infectious, i.e. cannot transmit HIV through sexual contact.”

It goes on to say that this statement is valid as long as:

the person adheres to antiretroviral therapy, the effects of which must be evaluated regularly by the treating physician, and
the viral load has been suppressed (< 40 copies/ml) for at least six months, and
there are no other sexually transmitted infections.
The experts noted the essential conundrum of proving the negative hypothesis (i.e. proving that something can never happen) but said “The situation is analogous to 1986, when the statement ‘HIV cannot be transmitted by kissing’ was publicised. This statement has not been proven, but after 20 years’ experience its accuracy appears highly plausible.”

A report on Aidsmap.com canvasses the implications of the announcement for medical practitioners, people with HIV, HIV prevention and the legal system.

As one colleague observed today, “I guess we know now what they’ll be fighting about at this year’s International AIDS Conference.”

HIV Can Be Transmitted Through Pre-Chewed Food, Researchers Say

HIV Can Be Transmitted Through Pre-Chewed Food, Researchers Say

HIV can be transmitted to infants through food that is pre-chewed by an HIV-positive parent or caregiver, CDC researchers said Wednesday at the 15th Conference on Retroviruses and Opportunistic Infections in Boston, the New York Times reports. Specific findings from the study have not been released, the Times reports.
According to the Times, pre-chewing food most often occurs in developing countries, where commercially prepared infant food and blenders are not available and caregivers need to soften food before giving it to an infant. The practice is rare in the U.S. but does occur among several racial and ethnic groups, according to a CDC study on infant feeding. >>
