Kosovo Mystery Illness Outbreak (1990)

In 1990, Kosovo experienced a mysterious illness outbreak among Albanian students, causing fainting, vomiting, and convulsions. Initially, there were suspicions that Slavic Kosovars had poisoned the Albanian students due to existing tensions, but independent commissions found no evidence of poisoning. Independent commissions concluded that mass hysteria, fueled by political tensions and a few actual cases of sickness, likely caused the illness.
