HIV Subtype Variation and Effect On Progression Rates
The HIV-1 subtype that an individual becomes infected with can be a major factor in the rate of progression from sero-conversion to AIDS. Individuals infected with subtypes C, D and G are 8 times more likely to develop AIDS than individuals infected with subtype A. In Uganda, where subtypes A and D are most prevalent, subtype D is associated with faster disease progression compared with subtype A. Age has also been shown to be a major factor in determining survival and the rate of disease progression, with individuals over 40 years of age at sero-conversion being associated with rapid progression.

“I have witnessed, and greatly enjoyed, the first act of everything which Wagner created, but the effect on me has always been so powerful that one act was quite sufficient; whenever I have witnessed two acts I have gone away physically exhausted; and whenever I have ventured an entire opera the result has been the next thing to suicide.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Measured by any standard known to science—by horse-power, calories, volts, mass in any shape,—the tension and vibration and volume and so-called progression of society were full a thousand times greater in 1900 than in 1800;Mthe force had doubled ten times over, and the speed, when measured by electrical standards as in telegraphy, approached infinity, and had annihilated both space and time. No law of material movement applied to it.”
—Henry Brooks Adams (1838–1918)
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
