Derby-based test manufacturer SureScreen Diagnostics will supply 20 million validated Covid-19 lateral flow antigen tests to the UK government. The tests will help meet the government’s efforts to deliver rapid testing asymptomatic individuals, to break transmission chains. The tests produce results in less than 30 minutes and are the first British tests to be validated in the Public Health England (PHE) laboratory.

University of California (USC) researchers have launched a new artificial intelligence (AI) tool to counter Covid-19 mutations and hasten vaccine development. The research team has developed a machine-learning model to speed up vaccine analysis that once took months or years, and now takes only minutes or seconds to find the best preventive medical therapy.

Ottawa researchers have discovered a test that can identify Covid-19 variants in wastewater. This was based on the recently detected variant in a sample of wastewater from Barrie, Ontario. Canadian researchers have already been testing wastewater for the SARS-CoV-2 virus. Research indicates that infected individuals can shed the virus through their faeces.
