New strand of HIV
Below is an article from cnn.com detailing the discovery of a new strand of HIV. It says that it may be difficult to detect this strand using conventional testing methods. Does anyone more information on this?

Well, that's certainly reassuring. I saw this article too, and I quote "The new virus is difficult to detect by conventional tests because it is not closely related to the other three HIV variants."
Thank you for your time, Teak and Vance!

Did she intially test positive via viral load test and NOT antibody test? has she tested positive via ELISA?
Yes it was discovered in 2004 with traditional HIV tests that were performed in that area.
So basically what you're saying is that her virus would be detected on a typical HIV test, but upon further investigation it was found to be a different/newly discovered subtype of the virus...?
This woman's different strain was picked up on through discrepancies in her VIRAL LOAD tests. She tested hiv positive on the antibody tests in 2004. They KNEW she was hiv positive, the important thing here is they discovered, AFTER she tested positive, that she's carrying a different strain.
The 62-year-old patient tested positive for HIV in 2004, shortly after moving to Paris from Cameroon, according to the researchers.
French doctors treating the 62-year-old Cameroonian woman who was living in Paris said they initially spotted some discrepancies in routine viral load tests. source
She responded to diagnostic tests for HIV-1 but further tests failed to pinpoint the viral subtype.
The virus was genetically decoded and then put through a computer model to compare its evolutionary past against known viruses, both HIV and its equivalent in apes, called simian immunodeficiency virus (SIV).
The strain was a "significant" match with SIVgor -- an immune deficiency virus found in gorillas.

All exotic strains are found in Africa and have not made it out of the area, normally like this women in Cameroon.
Europe, Americas and Asia have tests for the common strains and no need for testing for obsecure strains only found in remote places.
