Where did the number 60% come from?

The specific figure is Figure 3, the last panel showing instant contact tracing (with an app). It shows what combination of % (symptomatic) cases isolated & % (pre/a-symptomatic) contacts quarantined would contain the virus or not.

If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then "add subtitles/cc". I really appreciate those who do this, as it helps make the lessons accessible to more people.
