Diseases of the Blood
[This is a journal handwritten by a vampire known only as Lady Incognita in which she describes two different blood diseases that, if contracted by ingestion of infected blood, might inconvenience a vampire with a brief illness. The bulk of the text is descriptions of symptoms and diagnoses of Red Thrombosis and Thandal's Paroxysm. Lady Incognita notes that, with a vampire's superior senses, it's possible to train oneself to recognise infected prey by scent before biting them, 'Red Thrombosis by a piquant, gingery odour, and the Paroxysm by a sharp astringency.']
