Enterobiasis (oxyuriasis) is a common infection in human caused by Enterobius vermicularis (E vermicularis), a human intestinal helminth. Because of the easy way of its transmission among people, it has an extremely high prevalence in overcrowded conditions, such as nurseries and primary schools. Oxyuriasis's symptoms are extremely diverse in children, ranging from nausea, diarrhea, insomnia, irritability, recurrent cellulitis, loss of appetite, nightmares and endometritis. Here we report a curious case of oxyuriasis in the settings of a refugee camp in Greece. The patient was a 10-year old Syrian female, who presented with unusual and vague symptoms like insomnia and irritability. Given the violent background of the Syrian warzone that the patient had escaped, she was firstly diagnosed with post traumatic stress disorder (PTSD) before eventually getting correctly diagnosed with enterobiasis. This infection is the first documented case of enterobiasis in the settings of a refugee camp and can highlight the unsanitary living conditions that refugees have to endure in those camps.
