What do you gain with pooled sample testing?
Cheaper than individual testing
What do the contingency plans look like?
If any new positive tests for PCR, you strictly isolate that person (and test for antibodies?)? What’s next? Test the whole camp? Send home everyone who is PCR-negative?
Depending on the location & facilities something to the tune of:
Immediate segregation into limited size capsules
Sanitation.
Individual PCR tests for everybody.
Isolation plan for positive cases - joint capsule/hospital/home/individual isolation
Camp disbanding transportation plan / continuing in capsules until additional cases are ruled out
All with a written plan of action and chain of command & responsibility.
