Viral load refers to the amount of HIV in the blood. An undetectable viral load is when the amount of HIV in the blood is so low that it canât be measured. Antiretroviral therapy (ART) reduces viral load, ideally to an undetectable level, when taken consistently and correctly.
HIV is most commonly passed on through unprotected sex. It can also be transmitted by coming into contact with infected blood â for example, sharing needles to inject steroids or drugs. The HIV virus attacks and weakens the immune system, making it less able to fight infections and disease.
