We were about to disagree with your identification until we learned on Wikipedia (not our favorite site to reference) that Euclidae is synonymous with Limacodidae, the family that contains Stinging Slug Caterpillars. This does appear to be a Stinging Slug Caterpillar, but we have not been able to locate a matching image online that might lead to a species identification. We have no medical credentials and we cannot dispense any medical advice, but we would encourage your acquaintance to seek medical treatment if symptoms persist.
