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.
