Doctors checked to see if HIV was still present anywhere in his body but found no virus anywhere. when symptoms of cancer returned.

HIV is generally difficult to cure because it is a virus that can evade treatment by lying dormant.

This means it no longer replicates and just sits quietly in your south korea telegram data cells. It was many years after the Berlin patient that doctors cured other HIV-positive patients through stem cell transplants. Similar to the Berlin patient, four positive patients were cured of their cancer through transplantation of stem cells carrying the mutation. Why We Can't Cure Everyone Although stem cell transplantation appears to be an effective treatment for some patients, there are some challenges with this treatment, such as finding a suitable donor. The donor must be compatible with the human leukocyte antigen or type of recipient.

This indicates the type of protein found on the cell surface. The donor's blood must also have mutations that are needed to confer resistance to the transplanted cells. This mutation is rare in the stem cell donor population. When combined with compatibility requirements there are fewer potential donors per patient. Refusing a transplant stem cell transplant can also lead to a complication called graft-versus-host disease, or graft-versus-host disease. This happens when you receive a transplant and the cells in the transplant attack your body.
