Virus is a bloodborne infection in which the virus damages or kills cells of immune system?

The statement is incorrect. A virus is not a bloodborne infection, but rather an infectious agent that can cause disease in living organisms. Viruses are not capable of damaging or killing cells of the immune system directly.

While some viruses can affect the immune system and cause immunosuppression, they typically do so by infecting and disrupting the function of specific immune cells. For example, HIV is a well-known virus that primarily infects and destroys CD4+ T cells, which are crucial components of the immune system's defense against infections. Other viruses, such as measles and influenza, can cause temporary immunosuppression during the acute phase of infection, making individuals more susceptible to secondary infections.

Therefore, it is inaccurate to state that a virus is a bloodborne infection that damages or kills cells of the immune system.
