Bird Flu Has Reached Africa. West Africa.

Does the sudden appearence of the Bird Flu in Nigeria, in West Africa, mean widespread, undetected outbreaks across the continent? After all, the closest source I last heard of was Turkey.

Awwww crap. My brother’s traveling to Cameroon (next to Nigeria) this summer. Better drop him a line.

If it was spread by a migrating bird (or flock), I think it could easily jump from Turkey to Nigeria without making intermediate stops. Although it’s also very possible that there have been undetected infections. I remember hearing that there were a couple deaths in Turkey that were probably due to bird flu but occurred before the outbreak and were attributed to other causes at the time.
