Okay.
Dr. Tam, in 2005 you co-authored a study. I'm going to quote from it. It found that:
...from March through May 2003, Canada introduced various measures to screen airplane passengers at selected airports for symptoms and signs of SARS.... In spite of intensive screening, no SARS cases were detected. SARS has an extremely low prevalence, and the positive predictive value of screening is essentially zero. Canadian screening results raise questions about the effectiveness of available screening measures for SARS at international borders.
In your view, Dr. Tam, are available screening measures for the novel coronavirus any more effective today than they were for SARS, when your study was published?
