ABSTRACT
Objective The objective of the paper is to investigate the presence of SARS-CoV-2 on inanimate surfaces in four healthcare facilities treating patients with COVID-19 and four quarantine regiments of provincial military commands. Methods From August to October 2020, a total of 468 one-off environmental samples consisting of inanimate surfaces, garbage, and wastewater were collected. The real-time RT-PCR assay targeting E and RdRp genes to detect SARS-CoV-2 and checklist and questionnaire of disinfection practices were employed. If detected by RT-PCR, then positive samples are subjected to cell culture to determine viability. Results The test results showed all samples (100%) to be negative with SARS-CoV-2 resulting in unperformed virus culture. As for recent disinfection practices, chlorine-based products dissolved at a concentration of 0.1% (1000 ppm) in the general context or 0.5% (5000 ppm) for blood and body fluid spills are routinely applied twice a day and at the discharge of patients or quarantined people. Conclusions The finding may illustrate the importance of disinfection practices in removing pathogens or significantly reducing SARS-CoV-2 contamination on environmental surfaces and waste.
ABSTRACT
The main purpose of this research is to propose and test a conceptual model that clarifies the relationship between green performance of hotels and customer loyalty with the mediating role of relationship quality. The data collected from 200 homestay tourists in Moc Chau national tourism area, Son La province, Vietnam through questionnaire survey was tested by applying partial least squares with SmartPLS software. Analytical results showed that the higher tourists perceive the homestay green performance, the tighter the relationship quality they have towards the homestays, which in turns stimulates their loyalty behavior. The evidence also indicated that relationship quality contributes as the partial mediator in the relationship between green practice and tourist loyalty. The theoretical and managerial contribution, as well as the limitation and future research direction were also discussed in the paper.
ABSTRACT
A cluster of severe acute respiratory syndrome coronavirus 2 infections in Danang, Vietnam, began July 25, 2020, and resulted in 551 confirmed cases and 35 deaths as of February 2021. We analyzed 26 sequences from this cluster and identified a novel shared mutation in nonstructural protein 9, suggesting a single introduction into Vietnam.
