<unk> -associated herpesvirus <unk> HV), also called HHV-8, is present in almost 100% of<unk>  sarcoma lesions, whether HIV-related, classic, endemic, or iatrogenic.<unk> HV encodes oncogenes, microRNAs and circular RNAs that promote cancer cell proliferation and escape from the immune system. Transmission In Europe and North America,<unk> HV is transmitted through saliva. Thus, kissing is a theoretical risk factor for transmission. Higher rates of transmission among gay and bisexual men have been attributed to "deep kissing" sexual partners with<unk> HV. Another alternative theory suggests that use of saliva as a sexual lubricant might be a major mode for transmission. Prudent advice is to use commercial lubricants when needed and avoid deep kissing with partners with<unk> HV infection or whose status is unknown.<unk> HV is also transmissible via organ transplantation and blood transfusion. Testing for the virus before these procedures is likely to effectively limit iatrogenic transmission.
