B97.35
Human immunodeficiency virus, type 2 [HIV 2] as the cause of diseases classified elsewhere
Clinical Classification Guidelines
Medical Intelligence & Overview
HIV type 2 (HIV-2) is a virus that causes HIV infections and related illnesses. Recognized under ICD-10 code B97.35, HIV-2 is primarily found in West Africa but is also present in other regions. Unlike HIV-1, which is responsible for the majority of global HIV cases, HIV-2 tends to spread more slowly and often causes less severe disease. This guide aims to provide a patient-friendly understanding of HIV-2, its causes, symptoms, diagnosis, and treatment options.
Causes & Symptoms
Clinical Causes: Transmission through unprotected sexual contact with an infected person Sharing of contaminated needles or syringes Mother-to-child transmission during childbirth or breastfeeding Blood transfusions with contaminated blood products (rare in countries with rigorous screening) Close contact with bodily fluids containing the virus
Key Symptoms: Night sweats Persistent fever Unexplained weight loss Swollen lymph nodes Persistent fatigue Muscle aches and weakness Skin rashes or sores Recurrent infections, such as herpes or pneumonia Diarrhea that persists over time Oral candidiasis (thrush)
Diagnostic & Treatment
Diagnosis Path: Diagnosis of HIV-2 infection involves blood tests that detect antibodies or the virus itself. Standard HIV tests may initially detect the presence of HIV-1 and HIV-2 antibodies; specific tests are necessary to distinguish between the two. Molecular tests like PCR can identify HIV-2 RNA in the blood, providing definitive confirmation. Regular screening and early diagnosis are crucial for managing the condition effectively and preventing transmission.
Treatment Protocols: While there is currently no cure for HIV-2, antiretroviral therapy (ART) can significantly decrease viral load, improve immune function, and reduce the risk of transmission. Treatment regimens may differ from those used for HIV-1 due to differences in virus susceptibility. It is important to work closely with healthcare providers to monitor treatment effectiveness and manage potential side effects. Early initiation of therapy can improve long-term health outcomes.
