The louse-spread diseases spread much more easily when weather is very
cold and people huddle together to keep warm. So, the cold weather did
contribute.

Napoleon had lost almost 65% of his half million member invasion force by
September 7 (Battle of Borodino), prior to the cold weather setting in.
Anyone who has been in the armed forces knows that soldiers are continually in
close proximity to other soldiers, cold weather was not a significant factor in
the spread of louse vectored diseases during the 1812 campaign.
