COVID and DataStream

Hello there,
I have an assignment and here are some details from my teacher:
Please access the link below. It is a Webinar regarding COVID and DataStream. I think we all know how influential this has been over the past 20 months. The presentation is about an hour.
Please view and provide to me a summary of the presentation. 1-2 paragraphs are fine. Give me at least one pro or con of the value of DataStreams regarding Public Health and its effect on the general population.
That’s all you need and please let me know if you have any questions.
