| There are many diseases that resemble the basic [[signs]] and [[symptoms]] of bubonic plague. Since bubonic plague has the ability to kill the majority of a population, it is an extremely concerning diagnosis. It is very important to check for these other diseases before a final diagnosis of bubonic plague is made. There are many other [[bacterial]] [[infections]] that could be mistaken for the bubonic plague.

| ==Differentiating Bubonic Plague from other Diseases==
| |
| | |
| ===Bubonic Plague===
| |
| *[[Streptococcal]] or [[staphylococcal]] [[adenitis]] (Staphylococcal aureus, Staphylococcal pyogenes)
| |
| **Purulent or inflamed [[lesion]] often noted [[distal]] to involved [[nodes]] (i.e., [[pustule]], infected traumatic lesion).
| |
| **Involved nodes more likely to be fluctuant.
| |
| **Associated ascending [[lymphangitis]] or [[cellulitis]] may be present (generally not seen with plague).
| |
| | |
| *[[Tularemia]] (Francisella tularensis)
| |
| **[[Ulcer]] or [[pustule]] often present distal to involved nodes.
| |
| **Clinical course rarely as fulminant as in plague.
| |
| **Systemic toxicity uncommon.
| |
| | |
| *[[Cat scratch fever]] (Bartonella henselae)
| |
| **History of contact with cats; usually history of cat scratch.
| |
| **Indolent clinical course; progresses over weeks.
| |
| **Primary lesion at site of scratch often present (small [[papule]], [[vesicle]]).
| |
| **Systemic toxicity not present.
| |
| | |
| *[[Mycobacterial infection]], including [[scrofula]] (Mycobacterium tuberculosis and other Mycobacterium species)
| |
| **With scrofula, [[adenitis]] occurs in [[cervical]] region.
| |
| **Usually [[painless]].
| |
| **Indolent clinical course.
| |
| **[[Infections]] with species other than M. tuberculosis more likely to occur in [[immunocompromised]] patients.
| |
| | |
| *[[Lymphogranuloma venereum]] (Chlamydia trachomatis)
| |
| **[[Adenitis]] occurs in the [[inguinal]] region.
| |
| **History of [[sexual]] exposure 10-30 days previously.
| |
| **Suppuration, fistula tracts common.
| |
| **Although LGV [[buboes]] may be somewhat [[tender]], exquisite tenderness usually absent.
| |
| **Although patients may appear ill ([[headache]], [[fever]], [[myalgias]]), systemic [[toxicity]] not present.
| |
| | |
| *[[Chancroid]] (Hemophilus ducreyi)
| |
| **Adenitis occurs in the inguinal region.
| |
| **Ulcerative lesion present.
| |
| **Systemic symptoms uncommon; toxicity does not occur.
| |
| | |
| *Primary [[genital herpes]]
| |
| **Herpes lesions present in genital area.
| |
| **Adenitis occurs in the inguinal region.
| |
| **Although patients may be ill (fever, headache), severe systemic toxicity not present.
| |
| | |
| *Primary or secondary [[syphilis]] (Treponema pallidum)
| |
| **Enlarged [[lymph nodes]] in the inguinal region.
| |
| **Lymph nodes generally painless.
| |
| **[[Chancre]] may be noted with primary syphilis.
| |
| | |
| *Strangulated inguinal [[hernias]]
| |
| **Evidence of bowel involvement.
| |

| ==Chest X Ray==
| |
| Some other infectious diseases can be differentiated by looking at chest x ray images. For example, [[SARS]], [[Hantavirus]] syndrome, and [[Anthrax]] all need to be ruled out because they do present with some similar [[Bubonic plague symptoms|Symptoms]]. An example of a chest x ray for Hantavirus and Anthrax is shown.
