Human Coronavirus 229E Is Still Infectious on Normal Touching Surface

來自動物的呼吸道的新病毒和重新出現的歷史性強毒株的進化,對人類健康構成了重大的威脅。人畜共患病毒株在人與人之間的傳播效率低下,一開始可能會限制傳播的傳播,但接觸受污染的表面可能會感染。包膜病毒通常容易受到環境壓力的影響,但是引起嚴重急性呼吸道綜合症(SARS)和中東呼吸綜合症(MERS)的人類冠狀病毒最近引起了人們對暴發期間接觸傳播的關注。人類冠狀病毒229E在一系列銅合金上迅速失活(幾分鐘內可模擬指尖污染),而Cu / Zn黃銅在較低的銅濃度下非常有效。暴露於銅會破壞病毒基因組並不可逆轉地影響病毒的形態,包括包膜的解體和表面尖峰的散佈。 Cu+和Cu++部分是造成失活的原因,合金表面活性氧的產生會增強這種失活,導致滅活的速度甚至比非包膜病毒在銅上更快。因此,銅合金表面可用於公共區域和任何群眾聚會,以幫助減少呼吸道病毒從受污染表面傳播,並保護公眾健康。 The evolution of new viruses from animal respiratory tracts and re-emergence of historically virulent strains poses a major threat to human health. The transmission of zoonotic virus strains from person to person is inefficient, and may limit the spread of transmission at the beginning, but it may be infected by contact with contaminated surfaces. Enveloped viruses are usually susceptible to environmental pressures, but the human coronaviruses that cause severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) have recently raised concerns about contact transmission…
