[Ger-Poland-Volhynia] Medical history

[Andrew Wilm]

Hello All:
   Does anyone know of a site where I can locate info about epidemics in
eastern Europe/Russia in the latter part of the 19 th. century?My ancestors
lost 7 children to a diphtheria epidemic in southern Russia during that
time.I`ve searched various sites already and also used Google,all to no
avail.I`m beginning to think that perhaps it was a very local event.If it had
been widespread I`d think there would be lots of mention of it.
