Mr. Chair, we all know that public health operates under 10 essential functions. I won't go into all 10 of those, but one of them is enforcing laws and regulations that protect health and ensure safety. Another is linking people to needed personal health services and ensuring the provision of health care when otherwise unavailable.
One of the services that is not being talked about a lot is the service of testing. We do know there are two different types of testing. Nucleic acid testing tells me immediately whether I have the disease or not, whether I have the virus, and serology assays tell me whether I've been exposed to it and whether I've developed antibodies to it.
Those things were brought up by Professor Attaran and as well by Dr. Strong on the question of testing, so my first question will be for Professor Attaran.
Professor, do you see the value of the expansion in the immunity testing as well, as we see it, especially for those people who are exposed to it—workers who had fallen, workers who are wanting to get back, our nurses and our doctors who have been exposed and want to get back to work—and how quickly they can do that?
