To the Editor:In a recent news story, Alex Kaat with Wetlands International (WI) seems awfully sure that wild birds didn't bring avian flu to Nigeria and won't spread it from there to Europe. So, scientifically, why is he so sure it won't spread to Europe via the ducks? Do they not fly from Africa back to Europe? From my understanding, many wild water fowl -- especially ducks -- show few if any signs of avian flu infection and spread the virus via their feces, which can be dropped en route onto non-wetland areas. In fact, in Eurasia, avian flu is spread via wild birds.Are WI or any of their partners testing the Nigeria/African ducks in any numbers to see if the population is harboring the virus? Are they only testing the birds that drop dead (i.e. swans in Italy and Greece) and not living populations of other birds/waterfowl?Alex Avery...
