Genomic surveillance with next-generation sequencing (NGS) can track infectious disease transmission and identify novel strains of coronavirus and other emerging pathogens. With near complete sequence data of pathogen genomes, we can implement effective infectious disease surveillance strategies to help prevent further transmission and infection.
Infectious disease surveillance with NGS can:
Genomic surveillance helps public health officials track the path of an epidemic, perform contact tracing, determine the rate of pathogen evolution, and understand if a pathogen is changing in ways that could impact diagnostic or therapeutic effectiveness.
As the coronavirus mutates, new variants evolve such as the Alpha (B.1.1.7, UK), Beta (B.1.351, S. Africa), Gamma (P1, Brazil), Delta (B.1.617.2, India) and Omicron (B.1.1.529, S. Africa) variants. Surveillance and monitoring are critical because mutations can result in greater transmissibility or infectiousness. These coronavirus mutations can potentially make vaccines less effective/protective or even evade test diagnosis.
NGS is a valuable technology for genomic surveillance of infectious diseases such as COVID-19. Not only can it track the prevalence of coronavirus mutant strains, NGS can also identify novel coronavirus mutations, unlike PCR technology. Using NGS, scientists can detect low-frequency minority variants and multiple polymorphisms as well as novel variants.
Genome-wide strain typing with NGS can help epidemiologists identify and characterize mutations quickly to prevent further spread. Strain-level tracing can support identification of outbreak clusters and transmission routes.
In contrast, PCR is designed to detect specific regions of the pathogen genome; it will not identify new mutations across rapidly evolving pathogen genomes. Furthermore, PCR performance can suffer if mutations occur in the primer or probe binding regions.
Monkeypox virus (MPXV) is a large, double-stranded DNA virus first identified in 1958. Historically, the monkeypox virus has caused sporadic human outbreaks in central and west Africa, with a mortality rate between 1% and 10%. In the spring of 2022, outbreaks were observed in non-endemic countries of Europe, North America, and Southeast Asia. Public health surveillance efforts are underway in these countries to prevent the further spread of the monkeypox virus.
NGS is a valuable technology for genomic surveillance of infectious diseases such as monkeypox. Not only can NGS track the prevalence of mutant strains, but it can also identify novel mutations. As a result, scientists can now employ NGS-based technologies to detect low-frequency minority variants, multiple polymorphisms, and novel variants with speed and accuracy in a high-throughput format. These factors are vital in helping epidemiologists identify and characterize outbreak clusters, transmission routes, and mutations to prevent further spread.
5524澳门24小时线路 is proud to have supported the global expansion of NGS capacity and capabilities for public health during the COVID pandemic. These resources can now be used for the surveillance of pathogens such as monkeypox virus, ebola virus, mycobacterium tuberculosis, and many others.

Detect and fully characterize a known virus. Whole genome sequencing via an amplicon approach is ideal for known viruses with small genomes. This method involves analyzing genomic regions of interest with ultra-deep sequencing of PCR amplicons.
Detect and characterize coronaviruses, flu viruses, and other pathogenic organisms, as well as associated antimicrobial resistance alleles. These insights can help public health officials monitor outbreaks and optimize infection control strategies. This method captures genomic regions of interest via hybridization to target-specific probes.
Comprehensively sequence all organisms in a given sample and identify novel, or emerging pathogens such as mokeypox virus. This NGS method can help accelerate outbreak investigations and support development of new laboratory tests.

Up to 75% of new or emerging infectious diseases are estimated to have zoonotic origins.1,2 We now know that zoonotic reservoirs are significant in the spread of pathogens. With NGS, it is possible to screen reservoir animals such as bats to predict and prevent viral pathogen outbreaks.
Infectious disease surveillance with NGS-based target enrichment or metagenomics can help us understand interspecies transmission, how zoonotic diseases emerge, spread and become resistant to common therapies, and enable us to better contain, treat and prevent disease outbreaks.
Targeted enrichment sequencing can be scaled up to monitor zoonotic pathogens, while genomic surveillance with metagenomics allows for unbiased, culture-free detection and identification of a broad number of pathogens. Metagenomics also helps us understand the relationship between our microbiome and pathogen interactions, which is important when designing measures to control infectious diseases.
