Summary
This study presents the first complete dengue virus type 2 (DENV-2) genome from Sierra Leone. The findings suggest DENV-2 diversification in Africa, highlighting the need for enhanced arboviral surveillance.
Area of Science:
- Virology
- Genomics
- Epidemiology
Background:
- Dengue virus (DENV) is a major global health threat, with over four billion people at risk.
- Most DENV infections are asymptomatic or present as non-specific febrile illness.
- Effective surveillance and diagnostics are crucial for managing dengue outbreaks.
