Human herpesvirus 8 (HHV-8), also known as Kaposi’s sarcoma-associated herpesvirus (KSHV), is transmitted through direct contact with saliva, blood, or other bodily fluids of an infected person. It is most commonly spread through sex, especially among men who have sex with men (MSM). Additionally, HHV-8 can be transmitted from mother to child during childbirth, and through blood transfusions and organ transplants from an infected donor.
HHV-8 is not very contagious and cannot be spread through casual contact, such as touching, sneezing, or coughing. It is also not spread through sharing food, dishes, or utensils, or through contact with animals.
The main symptom of HHV-8 is a type of skin cancer called Kaposi’s sarcoma, which can appear as purple or red spots on the skin. Other symptoms may include fever, night sweats, fatigue, and weight loss. People with weakened immune systems, such as those with HIV/AIDS, are more likely to develop Kaposi’s sarcoma after being infected with HHV-8.
If you have been exposed to HHV-8, it is important to talk to your doctor right away. They can order tests to determine whether you have been infected and provide treatment options if needed. Treatment usually involves antiviral medications, chemotherapy, or radiation therapy.
