Briefly explain why this problem is worth addressing, both from a practical/societal and scientific point of view.

This document is part of a research proposal, but it is terribly written and I would like to ask if you could rewrite it in a way, which is:
I need help with the citings, I only put URL in there because I am not sure how to cite the website properly.
I would like to make this document well-structured, have the ordering of sections hierarchical and logical. That all information occurs at the correct place. Level of detail is appropriate throughout. Formulations in the text are correct, clear, exact and concise etc.(Basically rewritten in a professional way.)
I need help with providing a clear description of the problem I plan to address, which is the challenges of screening people for SARS-CoV-2 in the general population.
Briefly explain why this problem is worth addressing, both from a practical/societal and scientific point of view. I think I already did that somewhere but I am not sure if that is in an acceptable way.
I need to provide rationale as to why am choosing these data, which I did, but I am not sure if it is clear enough.
