冠状病毒持续多久？如果你感染了新冠病毒-19，你会有什么期待
一个冠状病毒病例会持续多久?专家表示，如果你感染了病毒，每天都要找出COVID-19的症状。
随着冠状病毒在美国继续流行，你可能想知道，如果你感染了COVID-19，你会生病多久。每个案例都是不同的，但经过数月的科学研究和数据收集，专家们有了一个相当好的想法。以下是你需要应对的症状，它们可能会在什么时候发作，以及你需要多长时间才能完全康复，能够安全地从自我隔离中解脱出来。
COVID-19第一个症状是什么时候出现的?
事实上，并不是每个感染新冠病毒的人都有症状世界卫生组织世卫组织表示，80%的感染是轻微的或无症状的。然而，这些人可能会出现发烧、发冷、咳嗽、肌肉或身体疼痛、疲劳、气短或呼吸困难，或味觉或嗅觉丧失。其他新冠病毒-19感染者报告头痛，喉咙痛、鼻塞或流鼻涕、恶心或呕吐、腹泻等。
这个疾病控制和预防中心（CDC）说，症状可能在接触病毒2-14天后出现。是的，那是一扇相当大的窗户。但美国免疫学家最近的一项研究发表在内科学年鉴，缩小范围。他们分析了180多例COVID-19病例，发现COVID-19症状平均只需要5天多一点。
研究小组还发现，97%的感染病毒的人会在首次感染后11天内出现症状。从发病第一天到最后几天，这些症状中的任何一种都可能在病程中的任何时候发作。
恢复需要多长时间？
新冠病毒-19的恢复期取决于疾病的严重程度。如果你的病情轻微，你可以在两周内康复。但对于更严重的病例，可能需要6周或更长时间才能感觉好起来，并且可能需要住院治疗。
根据疾病预防控制中心的说法，老年人和患有严重疾病的人基础性疾病与心脏病、肺病或糖尿病一样，新冠病毒-19可能会导致更严重的并发症。
什么是“病毒持续性”，它如何影响疾病的进程？
有时冠状病毒的存活时间比预期的要长，科学家们仍在试图弄清楚为什么会在一些患者身上发生这种情况，它在个体中是如何变化的，以及病毒在体内存活的确切时间。这就是所谓的病毒持久性,它会影响一个人有传染性的时间，因此他们应该被隔离多长时间。
“病毒清除是指感染病毒的消失，或者是对治疗药物的反应，或者是机体免疫反应的结果。”查尔斯·贝利他是加州奥兰治县圣约瑟夫医院和教会医院感染预防医学主任健康. “这意味着从感染中恢复并缺乏持续的传染性。另一方面，病毒持续性是指在急性病毒感染症状消失后，病毒通常在特定类型的细胞内持续存在。”
病毒持续存在见于HIV、慢性肝炎、水痘/带状疱疹和其他疾病单纯疱疹和爱泼斯坦·巴尔。虽然它不是典型的急性呼吸道感染（如新冠病毒-19）的特征，但研究表明，一些人确实存在持续的新冠病毒-19感染。一项来自中国的研究发表在定量成像在内科和外科证明了这一点：在研究中，一名妇女有轻微的新冠病毒-19症状，在2-3周后消失。然而，她在两个多月内仍保持阳性诊断状态。
你什么时候能在公共场所安全出门？
在感染新冠病毒19后，在公共场所外出的最大风险是将病毒传播给他人。但是，如果您遵循这些指导原则，就可以将危险降至最低。
贝利博士说：“在大多数情况下，10天后的传染性可以忽略不计，但对于免疫系统受损的人来说，这段时间可能会更长，例如两周或更长。”。“如果可行的话，应该考虑延长这些人的隔离时间，可能是两周甚至三周，并且应该鼓励他们在公共场所冒险时戴上口罩。”（每个外出的人都应该这样做，因为他们不能与社会保持距离。）
并不是每个人都需要接受COVID-19检测。轻度疾病患者可以在家中隔离和康复，但如果你有症状并希望接受检测，或如果你曾与确诊病例的人有过密切接触，一定要找到当地的检测地点。
相关的：你可以不戴口罩吗？健康专家称
根据你的整体健康状况和疾病的严重程度，你的医生将能够建议你是否需要检测，以及隔离多长时间。这个疾病控制中心提供以下经验法则：如果你认为或知道自己感染了新冠病毒，你需要在症状出现后10天内远离他人。你还需要24小时不发烧（不服用退烧药），在你与他人相处之前，你的其他症状必须得到改善。
再次冒险进入这个世界并不意味着将谨慎抛向远离它的风。豪尔赫·沃纳斯，医学博士，美国急诊科医学主任普罗维登斯玛丽小公司医疗中心在加利福尼亚州的托伦斯，他建议“在几周内格外小心”
“保持身体距离，戴上口罩，经常洗手——这些是目前最好的做法，”他告诉记者健康. “没有理由不太小心。除了常见的建议外，还要小心与你交往的人，特别是高危老年人和有共同疾病的人，”又名健康并发症或免疫力受损。
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控制中心,谁，以及他们当地的公共卫生部门作为资源。
