Treatment and Prevention of Cytomegalovirus Infections
Treatment of systemic virus diseases is still largely in the experimental stage, although rapid progess is being made. The basic problem has been that putative antiviral agents are either not effective enough or are too toxic. Evaluation of the effect of these drugs is also difficult. Frequently, the disease that is treated has a variable course, and the demonstration of efficacy of an antiviral may not be possible except by a blind, controlled study in which the drug-treated group is compared to a placebo-treated group. Such studies are expensive to undertake, and although the knowledge gained is usually solid, it is often limited.
