Classification of HIV/AIDS according to CDC guidelines
Stages of HIV infection based on CD4 count and clinical symptoms
The CDC classifies HIV/AIDS into stages based on CD4 count and symptoms. Early diagnosis and treatment are crucial for managing the disease effectively.
Classification of HIV/AIDS According to CDC Guidelines
Human Immunodeficiency Virus (HIV) infection progresses through distinct stages based on clinical symptoms and CD4 cell count. The Centers for Disease Control and Prevention (CDC) provides a classification system for better understanding and management.
Stages of HIV Infection
Stage 1: Acute HIV Infection
Occurs within 2-4 weeks post-exposure. Characterized by flu-like symptoms and high viral load.
Stage 2: Chronic HIV Infection (Clinical Latency)
Can last for years. Virus remains active but reproduces at low levels. CD4 count decreases gradually.
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
Severe immune suppression (CD4 count <200 cells/mm³) leads to opportunistic infections and malignancies.
Importance of Early Diagnosis and Treatment
Regular screening and antiretroviral therapy (ART) significantly improve prognosis and reduce transmission.
Conclusion
Understanding HIV stages allows for timely intervention, improving quality of life and public health outcomes.
