A low-cost genome sequencing technique that was used by thousands of laboratories globally to spot COVID-19 variants will be extended to cover all pathogens, in an ambitious new Wellcome Trust-funded project launched today. The ARTIC-2 project is led by the University of Birmingham and brings together researchers from the Democratic Republic of Congo, Ghana and Kenya with expertise in responding to numerous viral threats using genomic surveillance, including recent outbreaks of Ebola virus and Mpox in Africa.

The ARTIC-2 project will develop the underlying technology for the surveillance of emerging pathogens around the world. ARTIC-2 will work alongside the Africa CDC, Asia Pathogen Genomics Initiative and the WHO International Pathogen Surveillance Network to ensure that processes can then be rolled out worldwide.

Genomic surveillance is a powerful tool in the fight against infectious diseases. By analysing the genetic makeup of pathogens like viruses or bacteria, scientists can track the spread of outbreaks and understand their evolution over time. This information can help public health officials predict future outbreaks, develop targeted treatments, and implement effective control measures. It also aids in tracing the source of an outbreak and understanding how it has been transmitted between different populations. Easy access to genomic sequencing will enable public health laboratories around the world to respond more quickly and effectively to outbreaks of new and emerging viruses as well as better understand the mutations that occur randomly which lead to immune evasion or increased resistance to treatments.

A key element of the ARTIC-2 programme will be the continued development of a low-cost laboratory protocols and equipment that significantly reduce the cost of sequencing. The team are focused on reducing the cost of sequencing to under £10 per sample, reducing costs by focusing on open-source methods and reducing the reliance on expensive proprietary equipment and reagents. Lower costs allow more labs to perform sequencing where it is badly needed such as in low- and middle-income countries (LMIC) and the global south.

The project will also improve the way in which data is shared between researchers through a new initiative called Pathoplexus. Better data sharing can significantly improve outbreak response and public health decision-making as it allows for more accurate monitoring and tracking of disease transmission, enabling early detection and control efforts. The team also aims to rationalise the approach to develop a knowledge engine that will link all aspects of existing processes and tools with new learning to provide a universal and global toolkit for surveillance of pathogenic threats.

Professor Elijah Songok, the acting Director General at the Kenya Medical Research Institute (KEMRI), said: 'KEMRI is at the forefront of the development and adoption of cutting-edge technologies to improve health. We saw the impact genomic surveillance during the COVID 19 pandemic, and this research provides a much-needed tool in ensuring we are adequately equipped in identification of emerging pathogens and the continued efforts in the fight against infectious diseases.'
