I was just thinking, is there a different word in dutch for "sickness"? Or is "ziekte" used for both, "disease" and "sickness"?
is "sickness" more of a general idea, meaning any light queasiness or common illness, like when you eat a foot-long hotdog and then go on a roller-coaster...or bumper cars! (??), or can you say "sickness" when referring to something serious, like the flu, or a fever?
as far as I know sickness, disease and illness are synonyms, ziekte means all of them.
