What about resistance?

One of the concerns with some of the drugs used to prevent and treat CMV disease is the issue of resistance. CMV can become resistant to the drugs. It then becomes more difficult for the drugs to control CMV disease. As well, resistance to one drug may lead to developing resistance to others. Ganciclovir is one of the drugs that CMV can develop resistance to rather easily, as well as foscarnet and cidofovir.
