B20.7: HIV disease resulting in multiple infections

HIV disease resulting in multiple infections, as indicated by ICD-10 code B20.7, is a specific stage of HIV (Human Immunodeficiency Virus) infection, in which the immune system has been severely compromised, making the individual susceptible to various infections. The virus targets the body's immune system, especially CD4 cells, often called T cells, gradually depleting their number, which makes it difficult for the body to fight off infections and diseases. In this advanced stage, multiple simultaneous infections, often called opportunistic infections because they take advantage of the weakened immune system, are common. Such infections might include pneumonia, tuberculosis, candidiasis, and various other bacterial, fungal, and viral infections. These infections often result in varied symptoms, depending on the infections present, but may include persistent cough, fever, weight loss, skin rashes, and fatigue. Over time, these multiple infections can contribute to the progression to Acquired Immunodeficiency Syndrome (AIDS), the most severe phase of HIV infection.
