The development of antiretroviral drugs has meant that life expectancy for people on treatment for HIV infection has signifi cantly increased. However, there are often side effects that can result in a reduced quality of life for those people on long-term treatment. Burnet scientists are unlocking the mysteries of how these drugs interact with cells, with the aim of improving the quality of life for many living with HIV. well with HIV eople who become infected with Project Leader, Dr Kate Cherry said that pervaded the early years of the PHIV still remain infected for life; anecdotal reports suggest that it may AIDS epidemic has slowly subsided, although the development of combination be possible to prevent many toxic side but the number of people affected by therapies that use several different effects with the use of safe, vitamin- HIV continues to rise.
