The epidemiological use of the term plague is currently applied to bacterial infections that cause buboes, although historically the medical use of the term plague has been applied to pandemic infections generally.

1)Causative agent: Bite from Ixodes Tick transmitting the bacterium Borrelia burgdorferi
Disease caused: Lyme disease
Known symptoms: Fever, headache, stiff neck or neck pain, fatigue, erythema migrans

(slowly-expanding “ bull’s-eye” rash)
(observed symptoms are in bold)

Reasons for diagnosis: Lyme disease is normally diagnosed by symptoms, physical findings (eg. rash) and the possible exposure to infected ticks. Since the 85 year-old man has been feeding stray cats and dogs, there is a high probability that the man could have been bitten by an infected tick.

Physical examination: Main method of diagnosis. At the early stage of the disease, serological testing is usually not done. Furthermore, patients of EM rash are not ususally tested on to determine the diagnosis. In both the early and late stage of the disease, there is a high possibility of false negatives. Late stage symptoms will be more difficult to diagnose due to the variety of symptoms that overlap with other better known diseases.

Serological tests: Western Blotting, Enzyme-linked Immunosorbent Assay (ELISA), Polymerase Chain Reaction (PCR) etc.
