Current advances in nano drug delivery system for dengue treatment and prevention

Abstract

Dengue is a most important mosquito-borne viral illnesses. The disease is caused by dengue viruses that have four serotypes: dengue 1, dengue 2, dengue 3 and dengue 4. Primary infection usually results in milder illness, while more severe disease occurs in cases of repeated infection with different serotypes. Nanoparticles can offer significant advantages over the conventional drug delivery in terms of high stability, high specificity, high drug carrying capacity, ability for controlled release, possibility to use in different route of administration and the capability to deliver both hydrophilic and hydrophobic drug molecules. Due to the high prevalence of dengue viruses, it is required to develop novel treatment strategies and provide the site-specific delivery of drug reservoirs.
