The infected birds that Cuba professes to worry about will be dead or too weak for the migration, meaning that only healthy birds will be migrating back to Cuba. The birds intentionally infected may not make it back to Cuba, but undoubtedly some newly infected birds, birds infected by infected misquotes, will make it back to Cuba.
And if there is any justice Fidel and his brother will be infected.
If any of the birds fly from the Gulf coast to Cuba they *will* be infected. The idea that the seasons change & the mosquitos are not active is ridiculous. There is *never* a season when we don't have active mosquitos here. If we are in drought conditions there might not be any active mosquitos or if the temperature is in the 40's or lower. Otherwise watch out!
