Eighteen persons involved in an epidemic of blastomycosis were followed for a period of 3 years. None of the symptomatic patients received antifungal therapy and all recovered spontaneously. During the period of follow-up observation all patients remained in excellent health, and none showed evidence of late exacerbation of the original illness. Two of the originally symptomatic patients continue to show stable pulmonary nodules on chest roentgenograms, whereas the previously abnormal chest roentgenograms in the other patients have become negative. Sixteen of these 18 patients showed a minimum of 5 mm of induration when tested with blastomycin skin test antigen. During the period of observation, the size of this induration tended to diminish.
对18例芽生菌病流行中的患者进行了为期3年的随访。所有有症状的患者均未接受抗真菌治疗，全部自行康复。在随访观察期间，所有患者健康状况良好，均无原发病迟发加重的迹象。最初有症状的2例患者胸部X线片上仍显示稳定的肺结节，而其他患者之前异常的胸部X线片已转为正常。这18例患者中有16例用芽生菌素皮肤试验抗原检测时硬结至少为5毫米。在观察期间，这种硬结的大小有缩小趋势。
