Once someone contracts HIV, what is the typical time to progression to AIDS? What is the current average life expectency once someone contracts HIV?
Response from Dr. Young
Without any treatment, the average time from infection to progression to AIDS (either with a CD4 count <200 or an AIDS defining event) is about 8 years. There is a lot of variability in this figure, and much appears to relate to host factors and the viral load "set point".
From the first AIDS diagnosis, in the pre-treatment (HAART) era, the average life expectancy was 3 years.
Now that we have effective therapies for HIV, the life expectancy for those infected is considerably longer (on average), and should be estimated in decades, assuming that one has access to qualified medical care and medications. -BY
