From a study carried out in 22 townships of the Etnean area, by interviewing 112 shepherds, it was confirmed that 90 of them (80.3%), once or more in their lives, had contracted myiasis by Oestrus ovis L., habitual agent of estriasis in sheep. The most frequent sites of involvement were the pharynx (77 times), often extending to the larynx, the conjunctiva (56), followed by the nose (32) and rarely the ear (1). Multiple simultaneous sites involvement was also frequent affecting 54.4% of the shepherds. The chief symptom was pain, sometimes accompanied by fever and malaise. The shepherds go rarely to see a doctor (only 7 out of 90), the greater part preferring traditional remedies. It is curious to note that myiasis associated with Oe. ovis was already observed more than 150 years ago by a Sicilian physician, G. A. Galvagni, who had pointed out the high incidence of the myiasis in shepherds in the area. The persistence of human myiasis in the Etnean area appears to be related to the fact that in this region the conditions of sheep farming and the lifestyle of shepherds have not changed so much since then.
通过对埃特纳地区22个乡镇的112名牧羊人进行访谈开展的一项研究证实，其中90人（80.3%）一生中曾感染过一次或多次由羊狂蝇（Oestrus ovis L.）引起的蝇蛆病，羊狂蝇是绵羊眼蝇蛆病的常见病原体。最常受累的部位是咽部（77次），常蔓延至喉部，其次是结膜（56次），然后是鼻子（32次），很少累及耳朵（1次）。多个部位同时受累也很常见，影响了54.4%的牧羊人。主要症状是疼痛，有时伴有发热和不适。牧羊人很少去看医生（90人中只有7人），大多数人更喜欢传统疗法。值得注意的是，150多年前，西西里岛的一位医生G. A. 加尔瓦尼就已经观察到与羊狂蝇相关的蝇蛆病，并指出该地区牧羊人蝇蛆病的高发率。埃特纳地区人体蝇蛆病的持续存在似乎与以下事实有关：自那时以来，该地区的养羊条件和牧羊人的生活方式变化不大。
