alexandrossfakianakis shared this article with you from Inoreader Seroprevalence of Kaposi's Sarcoma‐Associated Herpesvirus and Risk Factors in Jiuquan area, China via Journal of Medical Virology Abstract The seroprevalence of Kaposi's sarcoma-associated herpesvirus (KSHV) is high in Xinjiang, China. But the seroprevalence of KSHV and risk factors are still unknown in Gansu which is adjacent to Xinjiang. 678 serum samples of general population and 87 serum samples of syphilis patients from Jiuquan, Gansu were tested for antibodies against KSHV including one latent protein (ORF73) and two lytic proteins (ORF65 and K8.1) using the ELISA. The total KSHV-seropositive rate was 15.9% in 678 serum samples of Jiuquan area, the KSHV-seropositive rate of males was higher than females (18.0% VS 14.6%, P > 0.05). The Uygur, Kazakh, Hui, Manchu and Mongolian population had a higher seroprevalence of KSHV than the Han population (43.8%, 40.0%, 34.5%, 30.3%, 35.0% VS 11.0%, respectively) among the ethnic groups in Jiuquan. Compared to the Han, Uygur, Kazak, Hui, Manchu and Mongolian people had an increase in the risk of KSHV of 528.9%, 439.1%, 325.6%, 251.6%, 335. 4% (P < 0.001, P < 0.001, P < 0.001, P = 0.002, P = 0.003, respectively). The serum prevalence of KSHV in subjects aged < 20 years, 20-50 years and > 50 years was 13.8%, 14.7% and 20.1%, respectively. Compared to the subjects aged < 20 years, 20-50 years and > 50 years had an increase in the risk of KSHV of 7.4% and 56.9% (P = 0.829 and P = 0.204, respectively). Compared to the positive rate of KSHV in the general population of Anhui, the positive rate of KSHV was significantly higher in the general population of Jiuquan area (15.9% VS 9%, P < 0.01). There was no significant difference in the positive rate of KSHV between the Han population of Jiuquan and the Han population of Anhui (P > 0.05). In the population of syphilis patients of Jiuquan area, the positive rate of KSHV was 30.7%, which was higher than that of the general population in Gansu area (P < 0.05). This study indicates that Gansu has a high seroprevalence of KSHV. Ethnicity and syphilis are risk factors for KSHV infection. This article is protected by copyright. All rights reserved.
