Paxlovid政府一直在推荐医生多开,因为有数据显示能防重症可是医生有些不爱开,政府就让药剂师也开,药剂师还是开的少。这药在美国目前是underused 这里是2023年一月的新闻。Drug interactions were one of the respondents' major concerns. 44% of physicians said they had not prescribed Paxlovid to people 65 and older because their patient had been taking another medication that is contraindicated with Paxlovid and that drug could not be discontinued. 41% said they hadn't prescribed Paxlovid because the risk of discontinuing a patient's medication was too high. https://www.prnewswire.com/news-releases/medscape-survey-finds-reasons-paxlovid-is-underprescribed-for-those-65-and-older-despite-its-effectiveness-against-covid-complications-301720681.html 其实这药厂自己实验有88%减低重症和入院率,老兵医院最新实验说还能降低26%长新冠。CDC美国疾控中心写的是降低51%入院率比药厂自己写的88%少些In a sample of U.S. COVID-19 patients, many of whom had previous SARS-CoV-2 infection or were vaccinated against COVID-19, the overall COVID-19 hospitalization rate was 51% lower among those who had received a prescription for Paxlovid for presumed mild-to-moderate COVID-19, compared with those who did not.https://www.cdc.gov/mmwr/volumes/71/wr/mm7148e2.htm Among the 24,142 poll respondents, 43% (10,423) reported they had been infected with COVID-19 since Jan. 1. When asked whether they had been treated with an antiviral medicine taken by mouth, only 11% indicated they had been prescribed an antiviral. https://news.northwestern.edu/stories/2022/08/study-finds-paxlovid-is-vastly-underused-despite-being-widely-available/ researchers from the Veterans Health Administration find that taking the medication may also reduce the risks of later developing long COVID, patients that took Paxlovid were 26% less likely to develop long COVID. https://www.npr.org/sections/health-shots/2022/11/08/1134982401/new-va-study-finds-paxlovid-may-cut-the-risk-of-long-covid
世界卫生组织 (WHO) 表示,考虑到该病毒目前在全球范围内的传播,无论 COVID-19 在当地的传播情况如何,个人在某些情况下都应该戴口罩。
如果一个人最近接触过 COVID,当有人感染或怀疑他们感染了病毒,当有人发展成严重 COVID 的高风险时,以及在拥挤的空间时,建议戴口罩。
世卫组织还扩大了对辉瑞抗病毒药物 Paxlovid 作为治疗药物的强烈推荐。 该机构继续强烈推荐葛兰素史克和 Vir 生物技术公司的 Xevudy(sotrovimab)和再生元制药公司(Regeneron)的 REGN-COV(casirivimab/imdevimab),因为它们当前变体的毒性有降低作用.

Hepa filter对virus也不管用吧,它只是能更好的过滤花粉之类的粉尘而已。

就算保持通風和防病毒病毒 近距離的時候總不能拿張過濾紙放中間或者開強力vaccum 把病毒抽離往上移動啊。保護的建議應該有條件限制的才可靠 不是一刀切的建議和執行
我的理解是filter能够有效降低气溶胶的浓度,大部分病毒会trap在filter上,空气中的病毒浓度会较低,从而降低感染风险。这和戴口罩是同一原理。
道理是这么讲,但口罩是覆盖在你的呼吸系统上面的,室内的filter并不。
