Has there been any analysis on how schools might affect the spread?

I'm a former teacher. I see folks discussing that hanta needs specific conditions to spread. I haven't seen any discussion on how many of those conditions are met within public schools in the US, specifically elementary schools. With the (up to 8 week?) incubation period and passengers that left the ship ~two weeks ago, I'm a bit nervous. Would love to read anything that considers this particular angle.
