That's an excellent question, sir. Thank you.
We actually sequence all positive tests in exactly the way you're referring to. So far, we've identified 1,700 variants of concern, or variants of interest, which are ones that are still under study.
I just need to go on to add that they were identified in people who were in quarantine. They were not released into the community. Those were people who tested positive; it was sequenced, and we knew while they were in quarantine. We caught them, in effect.
