You may well be right regarding
the USA, but the picture in the UK isn't
so clear. Manley refers to dealing with AFB at the beginning
of the last
century; he doesn't give the year but it appears to have been
around 1910. He
tried several treatments which didn't work, including one developed
in France
and Germany, so the disease had evidently been around for a long
time, and
was well established before moveable frames or foundation were
in general use
here and on the continent. No UK source I've come across says
anything about
its having become more common in the 20th Century. EFB is a puzzle.
It was
localised here until fairly recently, and has since become commoner;
it's now
running at about 1000 cases a year. It's very much a disease
of southern
England, and it's hard to think of a factor which would be at
work there but
not in Wales or Scotland.
