While most COVID-19 cases have been traced via patients’ travel history or contact tracing, these methods are potentially misleading as it depends on the information provided by patients. Genome sequencing may offer a better solution.
Researchers from Cambridge, UK, and Germany have reconstructed the early “evolutionary paths” of COVID-19 in humans – as infection spread from Wuhan out to Europe and North America – using genetic network techniques. The research also revealed three distinct “variants” of COVID-19 – type A, B and C.
Science, Technology and Innovation Minister Khairy Jamaluddin recently announced that genome sequencing is being developed in Malaysia to detect mutations in the COVID-19 samples. We asked expert on the significance of this process.
