19:55 our contact information that the school staff ensured everyone got an email copy of as soon as possible when we knew an exposure had occurred. And then the school administration was able to provide us with the immunity information they had on students and staff so that we could try and quickly identify who was that group that was at the highest risk for getting ill. And the school staff were a really amazing partner. They worked to identify the students and the staff who they did not have some immunity information for, and started reaching out to them to ask them to find that if possible. And so then again, those who had that proof of immunity were able to kind of continue going to work, school, everything like that as normal, and just were told to watch for symptoms and to let us know if they developed. And due to the high vaccination rate at the school among students and staff, that was the case for the vast majority of people. Clark County did follow up with 36 individuals who did not have some evidence of immunity.

20:54 And so these people were called by a member of our team to ensure they were aware of their exposure and explained that need for quarantining for the next 21 days and started the process of active monitoring. They were offered the choice of daily phone calls for a member of our team or daily automated text messages, where they would get a message with a secure link to a survey where they could report what, if any, symptoms they were experiencing that day. And a member of our team would review the responses, and then we would follow up if there were any symptoms that were suggestive of measles reported. Fortunately, we had no additional cases from the school that were identified. And this is likely due to, again, that high number of people who had a known immunity to measles and are quick separating out of ill individuals and all of the individuals who were exposed and not immune so that anyone that did get ill was not out in the community while they were contagious.

21:53 Next slide, please. The second public exposure was that healthcare setting, where a contagious individual went to get some measles testing. There were a lot of really great precautions taken to minimize the exposure here. We called ahead, the facility was aware, the potentially contagious person was wearing a mask, and the testing was planned for the end of the day when there wouldn't be many people around. But the individual did have to go through an area where others were present.
