U84: Resistance to other antimicrobial drugs
U84.2: Resistance to antiviral drug(s)
Resistance to antiviral drugs refers to a scenario where certain viruses in the body cannot be treated effectively by medications designed to combat them. This resistance typically occurs when viruses mutate or change over time, resulting in a reduced ability of specific antiviral drugs to inhibit or kill them. Viruses that are resistant to antiviral drugs can cause infections that are harder to treat and may progress more rapidly or severely. This medical condition does not typically produce its own symptoms, but instead can enhance the symptoms and complications of the viral infection with which it is associated. Such infections may stay longer in the body, can be more difficult to manage, and can potentially lead to an increased risk of disease transmission.
