Significance: Human ehrlichiosis is a tick-borne rickettsial disease of great public health concern in the United States. Clinical diagnosis of ehrlichiosis has been difficult because of its nonspecific presentation, which includes fever, headache, myalgias, arthralgias, and nausea. Ehrlichiosis is easily confused with other illnesses such as influenza and other tick-borne zoonoses, including Lyme disease and Rocky Mountain spotted fever. PCR methods enable early, specific diagnosis and treatment of erhrlichiosis.
