Preliminary Study of Early, Primary HIV Infection in a High Risk Cohort

Preliminary Study of Early, Primary HIV Infection in a High Risk Cohort.

The study of early, acute HIV infection is critical to understanding subtype-specific pathophysiologic differences, since up to 50% of acute HIV infections may be incapacitating. This study will establish whether the patient population of the Thai Red Cross Anonymous Clinic is suitable for the study of early, acute infection.

This study will utilize existing (collected after 1 January 2006) and prospectively collected HIV seronegative clinical specimens not used as part of any research protocol. The specimens in this study are discarded anonymous samples from the Voluntary Counseling and Testing (VCT) facilities at the Thai Red Cross Anonymous Clinic in Bangkok, Thailand. The specimens cannot be linked to the tested subjects. The samples will be labeled using the anonymous clinic identification number which is a 7 digit number with the first 2 digits representing the year and the following 5 digits representing the sequence of which the client sought care in that calendar year.
