B20.3: HIV disease resulting in other viral infections

HIV disease resulting in other viral infections, coded as B20.3 in the ICD-10 WHO 2016 classification, refers to a specific stage of Human Immunodeficiency Virus (HIV) where the immune system is compromised enough to allow other viral infections to occur. The infections might not ordinarily pose a threat for someone with a healthy immune system. HIV is a virus that specifically attacks the immune system, reducing its capacity to combat everyday infections and diseases. It's primarily transmitted through unprotected sexual contact, sharing of needles, or from mother-to-child during birth or breastfeeding. Symptoms can vary widely but frequently include persistent tiredness, recurrent fevers, drastic weight loss, and opportunistic infections. Over time, without appropriate treatment, HIV can progress to a more severe stage known as Acquired Immunodeficiency Syndrome (AIDS), which allows further life-threatening infections and cancers to develop.
