I believe we should cancel.
As mentioned we do not have proper hygiene at the camp.
Majority of the attendees are elderly and children even babies. Their risk factors are higher.
We also cannot control the coming in and out of attendees and day visitors.
We know God can protect us. But He also does not want us to take the risk.
Things is getting worst not better with this virus.
May God guides your decision on the 12th of March.
