Viral infectious illnesses represent a severe hazard to human health due to their widespread incidence worldwide. Among these ailments, the dengue virus (DENV) infection stands out. World Health Organization (WHO) estimates that DENV infection affects ~400 million people each year, with potentially fatal symptoms showing up in 1% of the cases. In several instances, academic and pharmaceutical researchers have conducted several pilot and clinical studies on a variety of topics, including viral epidemiology, structure and function analyses, infection source and route, therapeutic targets, vaccinations, and therapeutic drugs. Amongst Takeda, TAK-003, Sanofi, Dengvaxia®, and Butantan/NIH/Merck, Dengvaxia® (CYD-TDV) is the only licensed vaccination yet; however, the potential inhibitors are under development. The biology and evolution of DENVs are briefly discussed in this review, which also compiles the most recent studies on prospective antiviral targets and antiviral candidates. In conclusion, the triumphs and failures have influenced the development of anti-DENV medications, and the findings in this review article will stimulate more investigation.

The dengue virus (DENV) poses a significant threat to human health, accounting for approximately 400 million infections each year. Its genome features a circular structure that facilitates replication through long-range RNA-RNA interactions, utilizing cyclization sequences located in the untranslated regions (UTRs). To gain new insights into the organization of the DENV genome, we purified the 5' and 3' UTRs of DENV in vitro and examined their structural and binding properties using various biophysical techniques combined with computational methods.

We describe a Qdenga-induced DENV-2-infection in a Swedish traveler. Comparative sequencing suggests that the vaccine contained a small fraction of identical virus as detected in the patient, suggesting a selection of a DENV-2-substrain with unusual amino acid substitutions. Further research on selection of, and possible effects of, Qdenga-substrain-infections is warranted.

Background: Although there is a rising trend in both dengue cases and immunocompromised conditions, there is limited research on how common severe dengue is in immunocompromised individuals. This data is key for those advising the ever-increasing numbers of immunocompromised travellers.
Methods: We conducted a systematic review and meta-analysis of studies reporting dengue frequency or outcomes in immunocompromised populations.

Patients with sickle cell disease (SCD) infected with dengue virus are at high risk of developing severe complications. However, the optimal management approach for this patient population remains unclear. We report two cases of dengue-associated multiorgan failure in adolescents with hemoglobin SC (HbSC) disease, both of whom recovered following structured symptomatic management.
