[Dengue treatments and vaccines]

Area of Science:

• * Virology and Infectious Diseases
• * Public Health and Epidemiology
• * Vaccinology and Drug Discovery

Background:

• * Dengue fever is a significant mosquito-borne viral illness, transmitted by Aedes mosquitoes, with increasing global incidence and geographic spread.
• * Severe cases manifest as dengue hemorrhagic fever, impacting tropical regions and posing risks to new areas.
• * The disease presents complex pathophysiology and four distinct serotypes, complicating vaccine development.

Purpose of the Study:

• * To highlight the urgent need for novel therapeutic strategies against dengue fever.
• * To emphasize the challenges in current dengue vaccine development and limitations of existing options.
• * To underscore the necessity of identifying new antiviral molecules.

Main Methods:

• * Literature review on dengue epidemiology, pathophysiology, and current medical countermeasures.
• * Analysis of challenges in developing effective dengue vaccines.
• * Exploration of potential avenues for antiviral drug discovery.

Main Results:

• * Dengue incidence and geographic range are expanding globally.
• * Vaccine development is hindered by viral complexity and serotype diversity.
• * Current treatments are limited, and available vaccines have usage restrictions.

Conclusions:

• * There is a critical need for innovative dengue vaccines and specific antiviral treatments.
• * Developing new antiviral molecules is essential to mitigate the public health and economic impact of dengue.
• * Addressing these challenges is vital for controlling dengue in endemic and expanding regions.
