Bubonic Plague Misdiagnosed As TularemiaRetrospective Serologic Diagnosis

JAMA. 1972;222(13):1642-1643. doi:10.1001/jama.1972.03210130034009

Recent experience has indicated that human plague in the United States is often misdiagnosed as tularemia or as other causes of acute lymphadenitis. Two cases of plague in 1968 and two in 1969 were diagnosed retrospectively. Two of 44 persons on whom a diagnosis of tularemia was made in 1970 were identified as having bubonic plague by use of the passive hemagglutination test and by means of epidemiologic studies.
