Seroprevalence of Kaposi's Sarcoma Herpes Virus in the United States
This study will investigate patterns of Kaposi's sarcoma herpes virus (KSHV) in the United States and its potential impact on the U.S. population. KSHV is a newly discovered virus that is strongly associated with Kaposi's sarcoma and primary effusion lymphoma. The high prevalence of KS and KSHV among HIV-infected homosexual men suggests sexual contact as a primary mode of transmission. Reports of non-sexual transmission in parts of Africa and the Mediterranean where Kaposi's sarcoma is endemic, and the identification of viral DNA in saliva and other bodily fluids, however, indicate the virus is also transmitted non-sexually. This study will:
- Compare the prevalence of KSHV among different demographic groups in the United States
- Examine the association between KSHV and high risk behaviors such as drug use (marijuana and cocaine), sexual behavior (age at first sexual intercourse and number of sexual partners), and medical risk factors (herpes simplex virus II, hepatitis B and hepatitis C)
- Estimate the prevalence of KSHV in the United States.
Data and blood samples for the study will be taken from the NHANES III survey. NHANES is a program of periodic surveys conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The survey is designed to provide national estimates of health status for the United States non-institutionalized civilian population by means of household interviews, standardized physical examinations, and blood sample collection and testing. NHANES III-the seventh in a series of national examination studies-was conducted from 1988 to 1994.
This study will use the HANES data to identify risks associated with a KSHV-positive blood test in the survey population. The study plans to include all 19,754 participants (67% of the 29,314 participants originally examined) for whom blood samples were collected and remain available.
