Hospitals can be a source of new infections. To reduce this possibility, Raventos and Sabata suggested that air curtains equipped with sprayers to nebulize an alcoholic solution could be used in hospitals to disinfect clothing, exposed body parts and objects that passed through to rapidly and economically reduce the In today's world, the requirement for genetic information security is an evergrowing need. The very information that allows us to understand the properties of a pathogen can also be misused through genetic manipulation for potential harm. Schumacher et al. characterized a general genetic information system from biological material collection through long-term data sharing, storage, and application in the context of security. They also discussed the challenges associated with wet and dry laboratories due to distributed devices and systems that are not designed to address the security of genetic information systems and the need for an extensive laboratory system to realize the potential of this emerging field and to protect the bioeconomy of all stakeholders. patients was 12.9% versus 1.8% among those who did not report close contact.
isothermal nucleic acid amplification techniques, which included conventional PCR and loop-mediated isothermal amplification (LAMP) methods, with hybrid techniques such as polymerase chain displacement reaction (PCDR) and a newly developed PCR-LAMP method. Based on their evaluation, they concluded that hybrid methods exhibited higher sensitivity and assay reaction rates than the classic LAMP-and PCR-based methods.To ascertain early warning signs for severe and critical patients with COVID-19, Xu et al. performed a quantitative analysis of chest CT images at the lung segment level. Their analysis showed that lung involvement in the ordinary and severe/critical groups reached a peak on the 18th and 14th day, respectively. In the first stage, the percentage of lung involvement (PLI) in the right middle lobe and the left superior lobe were significantly different between the two groups. In the second stage and the fourth stage, there were statistically significant differences in PLI between the two groups in the whole lung, right superior lobe, right inferior lobe and left superior lobe. They observed that the rapid progress of the lateral segment of the right middle lobe on the second day and the anterior segment of the right upper lobe on the 13th day may be an early warning sign for severe/critical patients. In addition to the contribution of these scientists toward our understanding of COVID-19 response, scientists from around the world are working to enhance our knowledge and understanding about this virus and trying to identify ways to counter and eradicate this disease. Even with all of our current understanding, many unanswered questions remain that will be worth exploring. The editors of this Research Topic would like to thank the many scientists for their contribution to our knowledge about this disease and their dedication to public health.
