Detailní popis
People who recently became infected with HIV often have a high level of the virus and may be highly infectious. If they have sex (especially anal intercourse) without condoms soon after they have been infected with HIV, there is a great chance that they may transmit the virus to others. When they learn of their HIV infection, some but not all men change sexual behaviors so as not to infect their partner(s) with HIV. Possible reasons for such behavior change include increase or decrease in drug use and what is going on within their sexual partnerships. A study that tracks men with recent HIV infection and their partners over time can provide information key to stopping further spread of HIV given that sexual behaviors can vary over time, especially during this most infectious period.
This study will look at how likely it is for HIV infection to be spread among partner types over time by recently HIV-infected men and their partners. The study will compare behaviors of recently HIV infected men to those with long-term HIV infection and no HIV infection. It will allow a study of sexual partnerships by actively recruiting sexual partners. We will also focus on the role of drug use, especially methamphetamine and how it changes behaviors over time. We will especially look at how different sex partners affects one's drug use and increases or decreases HIV transmission. The study will enroll 150 recently HIV-infected men who have sex with men and follow them for a year. In addition, up to 6 sexual partners of each recently HIV infected individual will be recruited and followed for a year. Some sexual partners will be HIV negative and some HIV positive. We will use their HIV status to compare behaviors over time in the group and between partners of the same status and partners of a different status. The results will be used in special formulas that will allow for a better understanding of behavior change by men with recent HIV infection. This new information will be key for designing new ways to target risk reduction for recently HIV-infected men.

HIV-
This study measured how transmission risks and partnership dynamics change over time among recently HIV-infected individuals and their partners comparing their behavioral patterns with those with chronic HIV infection, no HIV infection, and HIV negative testers.
Of special focus was the role of drug use, especially methamphetamine, in affecting behaviors over time, and how partnership dynamics interact with drug use to allow for HIV transmission.
The study compared behaviors of recently HIV infected men to those with long-term HIV infection and no HIV infection.
We looked at how different types of sex partners affected one's drug use and consequently HIV transmission risks including having a prevalent sexually transmitted infection (STI).
The study enrolled 105 HIV- recently tested men who have sex with men (MSM) and followed them for a year.

HIV+ Acutely Infected
This study enrolled and followed 125 acutely infected HIV+ men.
It measured how transmission risks and partnership dynamics change over time among recently HIV-infected individuals and their partners comparing their behavioral patterns with those with chronic HIV infection, no HIV infection, and HIV negative testers.
Of special focus was the role of drug use, especially methamphetamine, in affecting behaviors over time, and how partnership dynamics interact with drug use to allow for HIV transmission.
The study compared behaviors of recently HIV infected men to those with long-term HIV infection and no HIV infection.
We looked at how different types of sex partners affected one's drug use and consequently HIV transmission risks including having a prevalent sexually transmitted infection (STI).
The study enrolled 321 recently tested men who have sex with men (MSM) and followed them for a year.

HIV+ Chronically Infected
This study enrolled and followed 91chronicially infected HIV+ men.
It measured how transmission risks and partnership dynamics change over time among recently HIV-infected individuals and their partners comparing their behavioral patterns with those with chronic HIV infection, no HIV infection, and HIV negative testers.
Of special focus was the role of drug use, especially methamphetamine, in affecting behaviors over time, and how partnership dynamics interact with drug use to allow for HIV transmission.
