Recent evidence has revealed that asymptomatic and/or persistent dengue virus (DENV) infections play a role in the cycling pattern of dengue outbreaks. These findings add a new dimension to the continually evolving search for effective prevention strategies in dengue. Disappointing outcomes of clinical trials in anti-dengue modalities have become commonplace. These failures may result from confounding variables and/or unresolved scientific issues that surround dengue, including the replication cycle of DENV in a natural setting, the target cells and reservoir for viral replication in vivo, and the effect of asymptomatic/persistent carriers in the dissemination of dengue. This article sets forth to address these issues using the most updated information available in the literature and to propose a novel antiviral strategy for the prevention and control of dengue.
