As an admin user, I want to be able to Enter the aggregate number of surgeries during a time range.

This will allow us to calculate the rate of infections in our dashboard.

Proposed Solution
The UI for this feature would be a simple form with a time range picker and a text field to enter the number of surgeries. The form would be available to admin users inside the app.

Implementation Plan
The implementation plan for this feature would be as follows:

1. Create a new form component for the app.
2. Add the form component to the app.
3. Create a model in the DB.
4. Add validation to the form to ensure the user enters a valid number of surgeries.
5. Save the number of surgeries in the database.
6. Update the ETL to include this metric.
