By Tarun Sai LomteJun 16 2023Reviewed by Lily Ramsey, LLM A recent study published in the Cell Host and Microbe Journal presented a modular framework for global sustainable networks of viral genomic surveillance.Background Virus genetic diversity and evolution can impact control efforts and dynamics of an outbreak. Monitoring evolutionary processes can provide more answers than conventional epidemiology.
The response to the ongoing human immunodeficiency virus pandemic led to many methodological advances in viral genomic surveillance and infrastructure. Related StoriesSystematic genomic surveillance was implemented for influenza, and the World Health Organization leverages these data to forecast antigen evolution and improve the selection of vaccine strains. The Ebola virus disease epidemic during 2013-16 in West Africa represented a watershed moment for near real-time surveillance of viral genomes.
By April 2020, 20 African countries had SARS-CoV-2 sequencing capacity, increasing to 39 by mid-2022. The trend in the Caribbean was also similar. This ensures the maintenance of equipment functionality, database management, supply stocks, access to diagnostic samples, the rationale for funding, and employment of trained personnel.
