If referring t fever, that is incorrect, however, it may be that cellular machinery might be slowed at the higher temp, thus impairing the virus ability to replicate.

Ok, ok, we've been through the live/die thing and forgive my laymans observations.

"Fevers aren’t always a bad sign; you may even have heard that mild fevers are a good indication that your immune system is doing its job. But fevers aren’t just a byproduct of our immune response."

"In fact, it’s the other way around: an elevated body temperature triggers cellular mechanisms that ensure the immune system takes appropriate action against the offending virus or bacteria."

Perhaps you could suggest proper language, like: dormant/not able to replicate/ whatever...that would be helpful.

According to Merriam-Webster a virus is classified as "nonliving". Hence they cannot die.

"Definition of virus

1a : any of a large group of submicroscopic infectious agents that are usually regarded as nonliving extremely complex molecules, that typically contain a protein coat surrounding an RNA or DNA core of genetic material but no semipermeable membrane, that are capable of growth and multiplication only in living cells, and that cause various important diseases in humans, animals, and plants"

They can be destroyed by UV-C wavelengths which warp their protein coating thus incapacitating their ability to couple with receptors on living cells.
