No you can still choose whether to be buried or a cremation - HIV is only transmitted through blood or bodily fluids.
Do You Have To Be Cremated If You Die With Aids?
There was a Woman my late Great Aunt knew and her Son was Gay and he died due to AIDS and he was buried in a casket and regular funeral but the thing was he had AIDS . No one knows how he contacted the disease could of been from being Gay or maybe he slept around with multiple partners no one knows but he lived a long life but he did die with AIDS . So no one knows why these things happen in life they just do ?
