Scientists from Britain's University of Oxford1 have developed a rapid Covid-19 test able to identify the coronavirus in less than five minutes, researchers said on Thursday, adding it could be used in mass testing at airports and businesses.
 
研究人员周四表示,英国牛津大学的科学家研发出一种新冠病毒快速检测方法,可在五分钟内识别出新冠病毒。研究人员补充称,这种方法可用于机场和企业的大规模检测。
 
The university said it hoped to start product development of the testing device in early 2021 and have an approved device available six months afterwards.
 
The device is able to detect the coronavirus and distinguish it from other viruses with high accuracy, the researchers said.
 
"Our method quickly detects intact virus particles," said Professor Achilles Kapanidis, at Oxford's Department of Physics, adding that this meant the test would be "simple, extremely rapid, and cost-effective".
 
Rapid antigen tests are seen as key in rolling out mass-testing and re-opening economies while the coronavirus is still circulating, and those that are already in use are faster and cheaper but less accurate than existing molecular2 PCR tests.
 
Siemens Healthineers on Wednesday announced the launch of a rapid antigen test kit3 in Europe to detect coronavirus infections, but warned that the industry may struggle to meet a surge in demand.
 
Although the Oxford platform will only be ready next year, the tests could help manage the pandemic in time for next winter. Health officials have warned that the world will need to live with coronavirus even if a vaccine4 is developed.
 
"A significant concern for the upcoming winter months is the unpredictable effects of co-circulation of SARS-CoV-2 with other seasonal5 respiratory viruses," said Dr Nicole Robb, of Warwick Medical School.
 
"We have shown that our assay6 (test) can reliably distinguish between different viruses in clinical samples, a development that offers a crucial advantage in the next phase of the pandemic."
