Question:

Hello Doc,
If the HIV virus cannot survive lower temperatures. I wonder, why isn't a clinically controlled reduction in body temperature to the point at which the virus dies is considered as a cure for HIV/AIDS?

Remember that if something works--a medicine or a procedure--outside of the body, in a test tube (so called "in vitro"), this does not mean you can actually work the same thing in a living, breathing, metabolizing organism. It would be impossible to work out a way to freeze the virus without destroying much valuable body tissue. Remember, the virus invades T-cells, which are part of the body's normal blood cells. It's a tempting idea, but doesn't (at this point in time) translate into something science can do "in the actual body" (in vivo).
