The bottoms leaves always die off at this time of year...
Those spots look like sun burn, the cells look like they have collapsed.

BTW paphs rarely get viruses and when they do they have been noted not to show any symptoms, but rather slowly die off sometimes. Large collections (I believe in Britain) were surveyed and paphs were the least affected of all the genera in the collection.
