Simulating the effects of mobility restrictions in the spread of SARS-CoV-2 in metropolitan areas in Portugal

PLOS ONE

Dear Dr. Oliveira,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Apr 16 2022 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

 

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols. Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io.

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Yes

Reviewer #2: Yes

2. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: Yes

Reviewer #2: Yes

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: the manuscript titled "Simulating the effects of mobility restrictions in the spread of SARS-1 CoV-2 in metropolitan

2 areas in Portugal", is well-presented. But there are few suggestions to be considered.

1. there are few grammatical and Syntax errors.

2. the quality of all figures especially 3 to 6 should be improved.

3. Conclusion should be more concise.

4. Similarly, abstract should be more focused on the study and its outcome/results. less background information will be enough.

Reviewer #2: In this manuscript the authors simulate the COVID restrictions and their effect on the spread of SARS-CoV-2 in two metropolitan cities Lisbon and Porto of Portugal. The study was based on SEIR model to estimate new daily infections. Four different mobility scenarios ranging from full restrictions to unrestricted full activity, were selected/simulated. The study has practical implications in determining/estimating the future number of infections as well as accepting the restriction practices in masses. The study has a strong hypothesis, the methodology is strong and results are presented in an intelligent fashion.

Revision 2

Review Comments to the Author

Reviewer #3: The manuscript "Simulating the effects of mobility restrictions in the spread of SARS-CoV-2 in metropolitan areas in Portugal" is well presented. The results are described in good fashion and can be implicated in COVID-19 restriction policies.

Does it need more statistical evaluations along with (SEIR model)?

R5: We thank the reviewer for the overall positive feedback.

Regarding the suggestion for more statistical evaluations along with SEIR model, we would like to enhance that the statistical analysis done had to be adapted to the data available. As mentioned in the manuscript, the number of daily infections are not available at municipal level (Lines 280 and following in the revised version with track changes), therefore no further comparison with the simulations could be done. Another limitation was that the data of people working in essential activities is not connected to the commuting data nor transport type, therefore they had to be used as separate scenarios (Table 1). Considering the characteristics (limitations) of the data and the objectives of the study, we have then decided to apply a time-series clustering analysis method (section 3.2.) which, to our knowledge, had not yet been used in this context, to obtain further understanding of the patterns and trends of the resulting simulations, that could not be obtained otherwise.

Reviewer #4: Authors have addressed all the suggested changes, the manuscript can be accepted after fulfillment of Journals requirements.

R6: We thank the reviewer for the positive feedback.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
