In the context of systemic diseases, what term is used for agents carried through the bloodstream?

The term used for agents that are carried through the bloodstream in the context of systemic diseases is "viremia." This specifically refers to the presence of viruses in the blood, which can lead to the spread of the virus throughout the body and possibly result in systemic infection. Understanding viremia is crucial in the study of infectious diseases, as it helps in determining how pathogens disseminate within an organism and the potential severity of the disease.

On the other hand, terms such as "acute" and "chronic" describe the duration and progression of diseases but do not specifically reference how agents move through the bloodstream. "Local" refers to a condition or disease effecting a specific area of the body rather than spreading throughout the system. Thus, these terms do not apply to the context of systemic agents being transported via the bloodstream.
