Stupidity: Throughout the movie, and especially up on the top of the apartment building before they get rescued at the beginning of the movie, Gerry counts 12 seconds to check if someone has been infected. Just to mention this apartment example, he gets blood on his face and spends more than 12 seconds getting up and to the edge of the roof, plenty of time to become "Zeke." He then counts 12 seconds, as if they would actually matter to his infection.
Stupidity: When they are in Italy on the boat, they find out they need to go to Montecarlo in order to reach Switzerland. They have a chopper. Italy is right next to Switzerland. It makes no sense that they would take a boat to Montecarlo to get to Switzerland, especially given the weather they'd have to sail through.
Stupidity: When she is getting the boots out, why is she sleeping outside when there is a fully covered wagon right there? (00:10:00)
Suggested correction: We don't know where in Italy they are. If they are all the way in the south, there is no way a helicopter could make it to Switzerland on a single tank. Then he would also have to consider clearance for airspace, where and how to refuel etc. In short, sailing to Monaco and flying to Switzerland from there is much easier.

Clearance to dock in Monaco is needed if you sail with a large ship. Same trouble than air clearance. Using a helicopter is still faster, even with the eventual refuelling. Switzerland via Monaco makes no sense. They would still need to use the helicopter or a car from Monaco on.
