Takanori Teshima from Hokkaido University in Japan said in the study: “Rapid detection of asymptomatic infected individuals will be critical for preventing Covid-19 outbreaks within communities and hospitals.”


Researchers carried out two virus amplification tests on the collected samples for study: the widely available PCR (polymerase chain reaction) test, and the less commonly used RT-LAMP test.

A research study forthcoming in The Accounting Review measures how effective the Securities and Exchange Commission is at detecting financial misreporting.
