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 prowazekii"that was most likely transmitted to the body through lice. Brill's Disease itself is not related to the presence of louse, but instead appears randomly many years after the original infection. The same symptoms seen in patients suffering from epidemic typhus are seen in patients with Brill's Disease, only in less severe form. 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.
