ABSTRACT
The new coronavirus (SARS-CoV-2) outbreak originating from Wuhan, China, poses a threat to global health. While its evident that the virus invades respiratory tract and transmits from human to human through airway, other viral tropisms and transmission routes remain unknown. We tested viral RNA in stool from 73 SARS-CoV-2-infected hospitalized patients using rRT-PCR. 53.42% of the patients tested positive in stool. 23.29% of the patients remained positive in feces even after the viral RNA decreased to undetectable level in respiratory tract. The viral RNA was also detected in gastrointestinal tissues. Furthermore, gastric, duodenal and rectal epithelia showed positive immunofluorescent staining of viral host receptor ACE2 and viral nucleocapsid protein in a case of SARS-CoV-2 infection. Our results provide evidence for gastrointestinal infection of SARS-CoV-2, highlighting its potential fecal-oral transmission route.
ABSTRACT
Taking the disaster recovery system in the data center of Quanzhou Orthopedic-Traumatological Hospital Affiliated to Fujian University of Traditional Chinese Medicine as an example,the paper introduces how to use all kinds of high-performance equipment and advanced VSS virtual exchange,VMware server virtualization and VPLEX storage virtualization technologies to eliminate the single-point fault hidden danger and realizes the high available data center disaster recovery construction with RTO =0.
