B20.2: HIV disease resulting in cytomegaloviral disease

HIV disease resulting in cytomegaloviral disease, also known as HIV-related cytomegalovirus (CMV) infection, is an illness that arises from a compromised immune system secondary to Human Immunodeficiency Virus (HIV) infection. The weakened immune system allows the opportunistic CMV to attack various organs in the body. This common virus, usually dormant in healthy people, can become active and cause severe health problems in those with lower immune responsiveness, such as individuals living with HIV. Disease symptoms vary and largely depend on the organs affected, commonly the eyes, gut, lungs, or brain. These might include vision problems, abdominal pain, shortness of breath, or neurological issues like coordination problems or seizures. This condition often signifies an advanced stage of HIV and typically presents in patients with very low CD4 cell counts, an indicator of compromised immune function.
