The Use of a Real-Time COVID-19 Standalone Device in an Emergency Department of a Tertiary Hospital in Singapore: A Pilot Observational Study

Round 1

Reviewer 1 Report

The present paper entitled "The Use of a Real-Time COVID-19 Standalone Device in an Emergency Department of a Tertiary Hospital in Singapore: A Pilot Observational Study" dealt with a subject of interest to the journal Covid where the authors carried out a study to evaluate the effectiveness of an autonomous system (hardware) in real time. The paper is well illustrated and therefore I recommend the work to be published in this current format.

Reviewer 2 Report

A novel, comprehensive, well performed work. Paper well written. I recommend the paper for publication. The only thing I would suggest to the authors is to specify in the title and in the abstract of the paper the type of the standalone device that they investigate in the paper. I leave it to the authors to decide about that.

Reviewer 3 Report

The reviewed article is interesting. It describes results of the use of standalone device designed to monitor potentially dangerous contacts in National University Hospital in Singapore. Investigations were performed in periods of 2 weeks each.  The dedicated application is described and some results obtained using this application were presented and discussed. Some technical problems occurring at an exploitation of the standalone device designed was also discussed.

The article is well organized and clearly written. The presented results can be interesting for many readers. The Conclusion is supported by results of investigations. In my opinion this article can be published in its current form.
