Thread – Camp in Georgia. At the time epidemic was starting to rise – with daily numbers worse than Ontario near its peak. 238 trainees/staff arrive June 17-21. 363 kids arrive June 21 with 138 trainees leaving. All COVID swab neg within 12 days.

Camp functioned as normal (staff masked, kids no - kids together doing kid camp things, no clear distancing/windows open). First positive case June 23rd – camp dismissed 27th and epi investigations. Large attack rate across all groups (44% with 260 total). 2/

Lessons learned
1) Overnight camps are a bad idea period right now, esp in large groups. Esp when COVID rates were high (I estimated 1-2% of population infected).
2) Use of testing as a method to do whatever we want is clearly flawed especially when prevalence is high. 2/

3) Screening for symptoms daily is of UTMOST importance – infected individuals coming in eventually likely mildly symptomatic. Not described well in this report but often minimized. As we open up everything this is especially important, particularly in schools.

Caveats
1) Likely multiple people were infected coming into the camp (~2-4 at beginning, more after 21st).
2) Nearly ¾ symptomatic when infected – and it begs the question if people were symptomatic and not reporting coming into health

3) Looking at incubation periods the bulk of transmission here seems more staff amplifying (june 17-21) and spreading to kids, and first symptomatic case too early for kid to staff transmission. Kid to kid transmission probably happening though to some degree at end.
