Much of the AMI building was said to have been very heavily contaminated, apparently much more so than any of the New York media buildings -- those buildings weren't shut down for massive clean-ups.
It's doubtful that people in Florida would have fewer nicks and cuts than people in New York. In fact, Floridians typically dress more informally than New Yorkers, so the people at AMI would probably have more exposed skin and fewer layers of clothing.
It really is a very distinctive difference, and it's hard to see what could have caused it.
