There are several ways the virus could become fitter - for example by being able to infect new cells more readily

A virus does not become "fitter" by killing its host more quickly. I becomes "fitter" by not killing its host at all.

Smallpox learned that lesson the hard way.

A popular theory on how HIV attacks .....

I believe it comes up from behind its victim....

A popular theory on how HIV attacks the body's immune system is wrong...

'Popular' meaning there was a consensus among scientists? Is one side calling the other heretics or loons?

Notice the funny kind of contradiction:

Old belief: Scientists have long believed that HIV causes the slow depletion of healthy white blood cells — the T cells which recognise infections so the body can fight them off — by causing infected T cells to produce virus particles before dying.

New belief: The results show that a "slow process must be active" in the depletion of the T cells, the authors wrote in the current issue of the journal PLoS Medicine.

I have a much simpler explanation for why it takes HIV so long to cause AIDS symptoms and AIDS death:

HIV does not cause AIDS.

This fits with the known facts much better than any HIV=AIDS theory.
