Can one with eczema become a monk? According to this site, one of the questions asked at ordination is "do you have eczema?" to which the reply must be "No, Venerable" in order to ordain. Is this accurate? Is it the case the one with eczema cannot ever become a monk?
An explanation (including the origin story) of this rule is given on pages 194 through 195 of The
Buddhist
Monastic
Code II -- The Khandhaka Rules

by Thanissaro Bhikkhu.

It says,


  Eczema covers a wide variety of skin diseases, differing from those included under
  “leprosy” in that they are not debilitating and do not ulcerate or ooze. Thus ringworm
  and athlete’s foot would come under this category. As under the preceding category,
  small, non-spreading infestations in an area covered when fully robed would be
  allowable.
