The fuckflu and your baseline VL have nothing to do with the particular strain of HIV you have acquired.
Many guys can have a very mild and almost an unnoticeable fuckflu. It could actually be missed if you weren't on the look out for some of the signs and symptoms. Some guys will get terribly sick and end up on IV fluids due to increased sweating, diarrhea and from nausea and vomiting.
The reason why nobody will have the exact same baseline VL is because this number is the number evolved after your body has given its "best shot" at fighting off the virus. Nobody will have the exact same immune response because we are all different.
Some guys won't budge for years and may remain around the 5-10,000 level while other's who may have the exact same strain may have VL of 100,000 and up to 600 - 700,000 VL.
Some even in the millions .. I know of a guy who's VL was over 6 million when not on meds. I also know of several guys (chasers) that carry his particular strain and their VL's are no where even close to 100,000 when not on meds.
Exact Genotyping and drug resistance testing can be done for anyone who is HIV positive.
I can't tell you for certainty if you will become drug resistant because you were reinfected with HIV with a different drug resistance pattern .. but it only seems logical that you will have inherited the drug resistance.
Also, the answer to "will I get the fuckflu again" if reinfected with a different strain .. extremely unlikely and I have never heard of this happening myself.
Also, I have one more comment to give here and that is in regards to the "Cuban Strain", it's an urban legend. If it were true don't you think that by now it would have been rampant in the larger cities esp on the eastern seaboard to include Miami and NYC? It's not and this name has been thrown around for years. It takes only one person to bring it into another country.
Like any disease in our ever shrinking world ... they can move from continent to continent in a matter of hours with frequent air travel. So where is it ?
