Elsevier established a free COVID-19 resource center in January 2020, offering information on the novel coronavirus in English and Mandarin. The center is hosted on Elsevier Connect, a public news and information website. Elsevier grants permission to make all its COVID-19-related research freely available in PubMed Central and other public repositories, allowing unrestricted reuse and analysis with proper attribution. This study investigates the stability of SARS-CoV-2 under various environmental conditions. The virus was tested at different temperatures, showing high stability at 4°C but sensitivity to heat, with inactivation occurring within 5 minutes at 70°C. On surfaces, SARS-CoV-2 was more stable on smooth surfaces like glass and banknotes compared to rough surfaces like tissue paper and cloth. A detectable level of infectious virus was found on the outer layer of a surgical mask on day 7. The virus also showed biphasic decay on smooth surfaces. Disinfectants had limited virucidal effects, except for hand soap. SARS-CoV-2 was stable across a wide range of pH values at room temperature. The study was supported by the National Institute of Allergy and Infectious Diseases and the Croucher Foundation. The research highlights that SARS-CoV-2 can be highly stable in favorable environments but is susceptible to standard disinfection methods. The findings contribute to understanding the virus's environmental persistence and transmission risks. The study was published in the journal "Cell Host & Microbe" on April 2, 2020. The article is available under a CC BY 4.0 license. The authors include Alex W H Chin, Julie T S Chu, Mahen R A Perera, Kenrie P Y Hui, Hui-Ling Yen, Michael C W Chan, Malik Peiris, and Leo L M Poon. The study references several prior works on SARS-CoV-2 and its environmental stability.Elsevier established a free COVID-19 resource center in January 2020, offering information on the novel coronavirus in English and Mandarin.
