It Tuesday's Maine CDC briefing, Dr. Nirav Shah reported that they have opened an investigation into a COVID-19 outbreak at Sanford High School that they have linked to gatherings from outside the school. This is the first outbreak investigation that the Maine CDC has opened into a public school which currently has 12 cases of COVID-19 associated with the outbreak.

The Maine CDC has identified a potential route of transmission that may have occurred at pick up football game on September 16 and a sunrise gathering of seniors that occurred around that same time.

Sanford Schools Superintendent Matthew Nelson moved all learning to remote only last week once the first cases of COVID-19 were discovered. "Nevertheless, this is a good opportunity and a good illustration of the fact that there can still be a risk of COVID-19, even when schools have moved to remote education," said Shah. "Out of school gatherings matter just as much as in school gatherings."
