Novel Coronavirus (COVID-19) Overview
Oxford Nanopore is working with public health laboratories around the world, and researchers in related areas, to support the current COVID-19 pandemic. This includes rapid sequencing of the novel coronavirus SARS-CoV-2, the virus that causes COVID-19, as well as approaches that characterise a broader range of pathogens in a sample. Oxford Nanopore has recently announced development of LamPORE, a rapid, low-cost and scalable assay for the detection of SARS-CoV-2.
A large number of scientists,from large centralised labs to smaller decentralised ones, are using nanopore sequencing to support rapid sharing of SARS-CoV-2 sequence data. Rapid data sharing has been key to the public health response, and researchers all over the world have been fast to share the genomes they have sequenced on public databases such as GISAID, GenBank or elsewhere.As numbers of cases increased, laboratories have built capacity to sequence larger numbers of the genomes, typically progressing from using the MinION device to the GridION device for sequencing. Thousands of genomes sequenced using nanopore technology are now available in public databases.
Oxford Nanopore’s vision is to support wide efforts to identify, track, trace, and isolate cases. We recently announced that we are in advanced development of a new assay, LamPORE, for SARS-CoV-2 detection. Alongside whole genome sequencing of the virus, this means that the range of Oxford Nanopore solutions for detection and analysis of SARS-CoV-2 can be performed in more and more locations.
Sequencing the virus can support ‘genomic epidemiology’- characterising the virus and helping public health authorities to understand the identity of the virus, whether it is changing and how it is being transmitted - all in conjunction with other epidemiological data.
The scientific community has previously developed methods for the rapid, near-sample nanopore sequencing of pathogens in multiple outbreak situations including Zika, Ebola, Yellow Fever and Swine Flu and a range of other pathogens. This experience has supported the rapid deployment of nanopore sequencing for the current outbreak.
Nanopore workflows can provide a consensus viral genome in 7 hours. See the resources below for more information.
Several researchers are also using nanopore sequencing to characterise multiple pathogens that may be present in a sample.

How can we help?
At this time, Oxford Nanopore staff are working with the community to support the development and sharing of best practice and protocols for the sequencing of this virus. We are offering technical support to public health authorities and researchers, and working to understand the needs of these users so that we can continue to provide the most useful support to the community. If you are a public health laboratory/scientist in the microbiology community and wish to discuss how we can support you in the current outbreak please get in touch.
Nanopore sequencing of the SARS-CoV-2 virus
Oxford Nanopore's sequencing technology has been used to sequence the virus in 7 hours. Many researchers are using the portable MinION device, with higher throughput labs using the larger GridION, and initial work starting on the ultra-high throughput PromethION. Early work on the smallest Flongle is expected to emerge soon.
Researchers are using a variety of different workflow approaches. For example:
Whole genome sequencing
For completing a whole genome sequence the ARTIC network has
issued protocols that enable rapid nanopore sequencing of the SARS-CoV-2 virus. Their latest pre-print describes how enhanced
SARS-CoV-2 genome coverage has been achieved while significantly reducing both hands-on time and reagent
costs.
You can also find information on currently supported workflows in the nanopore community (login required).
Direct RNA sequencing
Researchers from Australia and Korea have performed direct RNA sequencing of the virus, providing insights into the transcriptome and base modifications of the virus.
Metagenomic sequencing
Multiple groups are investigating approaches that characterise not only the SARS-CoV-2 virus, but other pathogens or microorganisms present in the sample. These aim to understand co-morbidity patterns of the disease, and also have the potential to be useful in broader surveillance of outbreaks in a population.
