Why is adherence to ART critical beyond the patient's own health?

• A. It helps achieve viral suppression and reduces transmission risk
• B. It has no impact on transmission
• C. It is only for weight management
• D. It isn't necessary after the first year

Answer: (A)

Maintaining adherence to ART keeps the HIV viral load suppressed. When the viral load is undetectable, the risk of transmitting the virus to others drops dramatically, a principle often summarized as undetectable equals untransmittable. That’s why adherence matters beyond the patient’s own health—it protects partners and public health by reducing transmission. If adherence falters, the viral load can rebound, increasing the chance of onward transmission and also raising the risk of drug resistance and treatment failure, which narrows future treatment options. The statement is not about weight management or a one-time requirement; ART is a lifelong commitment to maintain suppression.
