#' Cholera case records Denmark, 1853.
#'
#' A dataset of cholera cases from two small Danish towns of Nykoebing (Felster) and
#' Frederikshavn in 1853. This set includes all recorded cholera patients.
#' Presumebly they were admitted to some temporary field hospital since
#' "discharge" dates are included. The towns would have been too small to have a
#' regular hospital however.
