Viiruskoormus

Viiruskoormus, also known as viral load, refers to the amount of virus present in a person's body at a given time. It is typically measured in copies of viral RNA or DNA per milliliter of blood or other bodily fluids. Monitoring viral load is crucial in managing viral infections, particularly in the context of HIV and hepatitis C.

In HIV infection, viral load is a key indicator of the effectiveness of antiretroviral therapy (ART). A low viral load, often below the level of detection (typically less than 50 copies per milliliter), is associated with a reduced risk of transmitting the virus to others and a lower risk of disease progression. Regular monitoring of viral load helps healthcare providers adjust treatment regimens to ensure optimal control of the infection.

In hepatitis C, viral load is used to assess the response to antiviral treatment. A sustained virologic response (SVR), defined as an undetectable viral load six months after the end of treatment, indicates a cure. Monitoring viral load is essential for guiding treatment decisions and ensuring long-term control of the infection.

Viral load testing is typically performed using polymerase chain reaction (PCR) technology, which can detect and quantify viral particles with high sensitivity and specificity. Regular testing and management of viral load are essential components of viral infection management, contributing to improved outcomes and reduced transmission.
