你需要知道的11种冠状病毒症状以及如何预防病毒
仅供参考:它看起来很像流感。
自2019年12月在中国武汉首次报道以来新型冠状病毒(2019冠状病毒病)已成为全球卫生问题。据世界卫生组织(WHO)报道，截至7月14日，全球已有1300多万人患病，死亡人数超过57万人。
虽然美国不同地区正在经历不同程度的COVID-19感染，但没有一个州是免疫的。目前，美国40个州的新病例呈上升趋势，佛罗里达州、加利福尼亚州和得克萨斯州等地疫情严重。
公共卫生官员现在认识到，人们可能会在出现症状之前传播疾病。最新修订的估计疾病控制和预防中心美国疾病控制与预防中心(CDC)表示，40%的人没有症状，一半的新病例是在感染者出现症状之前被传播的。
如果你碰巧感到有什么东西出现，你怎么知道是不是COVID-19?以下是需要注意的核心症状，以及它与其他疾病的区别。
冠状病毒有哪些症状?
首先，冠状病毒是一组不同的病毒，目前有新闻价值的冠状病毒毒株COVID-19的症状与其他冠状病毒毒株不同。
有三个症状:发烧、咳嗽和呼吸急促——最初被认为是COVID-19的核心症状，但越来越清楚的是，这种疾病的症状和体征可以非常多样化。疾控中心修订并扩大了的症状列表不止一次。发烧或发冷、咳嗽、呼吸短促或呼吸困难仍然是可能的指标。其他迹象包括:疲劳;肌肉或身体疼痛;头痛;味觉或嗅觉的新丧失;喉咙痛；鼻塞或流鼻涕;恶心或呕吐;和腹泻。
COVID-19的迹象和症状看起来很像流感。美国疾病控制与预防中心说，常见的流感症状包括发烧、咳嗽、喉咙痛、肌肉疼痛和头痛。
据报道，与病情较轻的患者相比，COVID-19住院患者中发烧、咳嗽和呼吸短促更常见更新中心指导．疲劳、头痛和肌肉疼痛的抱怨在病情较轻的人群中更常见，这些人不需要住院治疗。轻微疾病也会出现喉咙痛、流鼻涕或鼻塞等症状。
起源于印度的Delta变种的症状与在美国传播的第一个变种的症状略有不同。“COVID现在的表现有所不同。这更像是重感冒;人们可能会认为他们只是得了某种季节性感冒，”伦敦国王学院流行病学教授蒂姆·斯佩克特解释道COVID症状研究在YouTube上发布的视频中．他解释说，德尔塔变体患者的头号症状是头痛，其次是喉咙痛、流鼻涕和发烧。“这些不是老的、经典的症状，”Spector说。“第五个是咳嗽，(尽管)它比较罕见。”他补充说，嗅觉丧失不在Delta变种患者报告的十大症状之列。
冠状病毒是如何进展的?
然而，COVID-19的进展差异很大。最初，一些人有非常轻微的症状，如头痛或低烧，而其他人根本没有症状。美国疾病控制与预防中心警告医护人员，在病情严重的人群中，“有些患者在发病一周后病情可能迅速恶化。”
美国疾病控制与预防中心建议，如果你认为自己接触了COVID-19，或者出现了发烧或其他症状，如咳嗽或呼吸困难，请联系你的医疗服务提供者。任何有呼吸困难或其他相关症状的人，比如胸痛、精神错乱或嘴唇或脸发紫，应立即就医。
如何保护自己免受冠状病毒感染?
的谁建议采取各种安全措施，以防止自身的冠状病毒，包括手和呼吸卫生。
首先，建议人们经常用肥皂和水清洁手或使用基于酒精的手凝胶。这也很重要，当咳嗽和打喷嚏时，人们总是用肘部或组织覆盖嘴巴和鼻子（然后立即将使用的组织扔掉并洗手）。人们也应该尽力避免别人发烧或咳嗽。
世卫组织说，避免接触眼睛、鼻子和嘴巴，因为如果病毒在你手上，它可以通过你的黏液膜进入你的身体，使你生病。
保持“社会疏远” - 在人们之间保持大约6英尺的缓冲区，以防止人员传输，这也很重要疾病预防控制中心建议。它还表示，在公共场合或在家人以外的人周围时，尤其是当你无法保持身体距离时，每个人都应该戴上口罩。
CDC补充说，每天清洁和消毒你接触的任何表面。如果你生病了，一定要待在家里康复。如果出现严重症状，请联系您的医疗服务提供者。
截至发稿时，这篇报道中的信息是准确的。然而，随着围绕COVID-19的形势继续发展，一些数据可能自发布以来发生了变化。在《健康》杂志努力使我们的故事尽可能最新的同时，我们也鼓励读者通过使用疾病预防控制中心，谁以及当地的公共卫生部门作为资源。
