Recent research has discovered that the virus can lurk deep within the bone marrow, where it evades the effects of treatments. This finding presents new challenges in treating individuals with HIV, as the virus can awaken and reactivate, potentially leading to a worsening of the disease. The Role of Bone Marrow in HIV The bone marrow and its role concerning the HIV virus is of paramount importance. Scientists have determined that long-lived bone marrow stem cells become targets for the virus, which hides within these cells.…
