In the absence of a vaccine against the AIDS virus, the most effective treatment method is aggressive treatment of HIV infections with cocktails of antiretroviral drugs, an approach known as highly active antiretroviral therapy or HAART.
A new study conducted in British Columbia has found that the infection rate in the province has been halved since 1996 by the widespread adoption of HAART, researchers reported online Sunday in the journal Lancet and at the International AIDS Conference in Vienna.
