Figure 4

Figure 4. Frequency of symptoms in patients with erythema migrans infected with Borrelia afzelii, B. garinii, or B. burgdorferi sensu stricto from central Europe and B. burgdorferi sensu stricto from the United States. A) Any symptom, B) individual symptoms. Patients were assessed for 8 symptoms (fatigue, arthralgia, myalgia, headache, fever, chills, neck stiffness, or malaise). White bars indicate patients from Europe infected with B. afzelii, light grays bars indicate patients from Europe infected with B. garinii, dark gray bars indicate patients from Europe infected with B. burgdorferi sensu stricto, and black bars indicate patients from the United States infected with B. burgdorferi sensu stricto. Differences between strains were assessed by using the Fisher exact test. p values are indicated. There were no differences between B. afzelii, B. garinii, or B. burgdorferi sensu stricto from Slovenia.
