Thank you, especially in COVID, this is not a theoretical question. This is of enormous practical consequence. Yesterday, I believe, Taiwan’s numbers show that all of our confirmed cases are during quarantine. There’s no reported cases outside of quarantine and even of those in quarantine, I think it was just five confirmed cases of Omicron. So obviously, we’ve done something right when it comes to contact tracing and surveillance because we’ve reduced the time it takes for exposure notification from used to take more than 24 hours last May when we faced our first in-real wave of alpha and but later on when we faced Delta and Omicron, our surveillance, contact tracing, is now less than 24 minutes before we can send out exposure notifications.
