Summary
Arthropod-borne animal virus (arbovirus) outbreaks, like Rift Valley fever (RVF), are increasing globally. Improved diagnostic methods are crucial for managing RVF and preventing its spread.
Area of Science:
- Veterinary Virology
- Epidemiology
- Public Health
Background:
- Arthropod-borne animal viruses (arboviruses) cause significant global livestock and economic losses.
- Rift Valley fever (RVF) virus is a major arbovirus responsible for lethal disease in livestock in Sub-Saharan Africa.
- Potential spread of RVF virus due to climate change, animal trade, and bioterrorism is a growing concern.
Purpose of the Study:
- To discuss current and developing diagnostic approaches for Rift Valley fever (RVF).
- To highlight the need for global harmonization of diagnostic assays.
- To emphasize the necessity for continuous improvement in diagnostic technologies.
Main Methods:
- Review of existing diagnostic assays for RVF.
- Discussion of emerging diagnostic technologies.
- Exploration of viral genome amplification and serological approaches.
Main Results:
- Diagnostic assays for RVF are available but face limitations in accessibility.
- There is a clear need for standardization and global harmonization of diagnostic methods.
- Advancements in biosensors and viral characterization technologies are emerging.
Conclusions:
- Continued improvement of standard diagnostic techniques is essential.
- Development of new embedded/syndromic testing and biosensor technologies is needed.
- Enhanced viral detection and characterization are critical for managing RVF outbreaks.
