Human herpesviruses (HHVs) are able to escape from complete clearance by the immune system. The analyses show 85 predicted open reading frames (ORFs), conservation with sequenced HHV-6A reference strain U1102, and closest identity to the recently determined GS strain, despite different geographic origins (United States and Gambia). Methods: A total of 20 (11 males and 9 females) histologically confirmed adults with AIDS-KS were recruited consecutively in 2007. However, few studies have directly examined children, particularly in locations where KS is not commonly endemic. Ercoli, L. The geographic distribution of HHV8 seropositivity generally parallels that of KS [6, 7]. In Uganda, HHV-8 seroprevalence was high early in adulthood (35.5% by age 21) without significant change thereafter.
In contrast, HHV-8 seroprevalence early in adulthood was lower in Zimbabwe and South Africa (13.7 and 10.8%, respectively) but increased with age. One C strain genome was present in all six independent lesions from an AIDS KS patient with disseminated disease, and the other represented a mosaic A/C recombinant genome from the HBL6 cell line derived from a BCBL tumor. More recently there have been reports that HHV-8 may also be associated with multiple myeloma (7, 44, 45). In conclusion, HHV-8 infection is substantially more common in Uganda than in Zimbabwe and South Africa. These findings help to explain the high KS incidence in the “KS Belt” and underscore the importance of a uniform approach to HHV-8 antibody testing.
