Brill-Zinsser Disease
Brill-Zinsser Disease (commonly known as Brill's Disease) is a form of epidemic typhus that occurs only in patients who have previously been infected by Rickettsia prowazekiithat was most likely transmitted to the body through lice.[6] Brill's Disease itself is not related to the presence of louse, but instead appears randomly many years after the original infection.[6] The same symptoms seen in patients with epidemic typhus are seen in patients with Brill's Disease, only in less severe form.[6] Brill's Disease can affect patients for the entirety of their lives, with cases being documented after more than forty years of contracting epidemic typhus.[6]
