N Engl J Med:新冠病毒感染者可能完全无症状!

2020-02-21 朱朱 文韬 中国循环杂志

研究人员发现,今年2月1日从湖北武汉乘机回德国法兰克福的126名旅客(大部分是德国人)中,通过咽拭子检测,有2人新冠病毒阳性,但他们没有发烧或感染的症状。 在飞行过程中,有10名乘客有新冠病毒感染病人接触史或有相关症状,但到达德国后病毒检测为阴性。

自新冠病毒感染疫情爆发以来,不断有个案报道表明,无症状者也会携带并传播病毒。
 
2月18日,新英格兰医学杂志在线发表的一项德国研究再次证实了这一点。
 
研究人员发现,今年2月1日从湖北武汉乘机回德国法兰克福的126名旅客(大部分是德国人)中,通过咽拭子检测,有2人新冠病毒阳性,但他们没有发烧或感染的症状。
在飞行过程中,有10名乘客有新冠病毒感染病人接触史或有相关症状,但到达德国后病毒检测为阴性。
 
其余的116名乘客(5个月至68岁,包括23名儿童)被送到法兰克福机场的医学评估中心,并由医生进行评估。
 
每位乘客要求报告有无发烧、乏力、喉咙痛、咳嗽、流鼻涕、肌肉酸痛和腹泻的症状,检查鼻子和喉咙有无感染迹象并测量体温。
 
仅一名乘客体温为38.4°C并报告有呼吸困难和咳嗽,但被送到医院后,通过RT-PCR检测咽拭子和痰液,病毒测试为阴性。
 但是,在114名乘客咽拭子病毒测试中,有2人(1.8%)检测出新冠病毒阳性。在细胞培养中分离出的病毒也有潜在的感染性。
 
这两名新冠病毒阳性的旅客被送至医院传染科,7天后,两人状态良好且无发热。
 
研究人员指出,对于无症状的人,仅仅用常规的症状筛查方法,可能会漏诊新冠病毒感染患者。
