TLDR

A simple Python command-line tool that asks about your symptoms and estimates your COVID-19 risk, then shows a visual report. Great for quick, private checks without a mobile app.

In plain English

This is a small Python program that helps assess COVID-19 symptoms from your computer's command line. Think of it as a lightweight, do-it-yourself version of India's Aarogya Setu app, which was widely used to track potential coronavirus exposure and risk. You run the program in a terminal window and answer questions about how you're feeling. It then maps those symptoms to estimate your COVID-19 risk. Beyond just giving you a yes-or-no answer, it generates a visual report using a charting library called matplotlib, so you can see a breakdown of the data on your screen. This would be useful for someone who wants a quick, private way to check symptoms without installing a full mobile app. For example, a student learning Python might run it as a fun project, or a small clinic could adapt it as a starting point for a simple screening tool. The README includes sample charts showing positive case data broken down by city, suggesting it can also visualize broader trends rather than just individual results. The project is straightforward and beginner-friendly, built entirely in Python with a command-line interface rather than a graphical app or web interface. The README doesn't go into much detail about how the symptom mapping actually works or what data sources it uses, so you'd likely need to look at the code itself to understand the logic behind the risk assessment.

Copy-paste prompts

Prompt 1
I cloned the z4nzu/covid-19 repo. Walk me through how to run the symptom checker from the command line and what questions it asks.
Prompt 2
Help me modify the covid-19 symptom checker so I can add new questions about taste and smell loss to the risk assessment.
Prompt 3
Show me how the matplotlib visual report is generated in the covid-19 repo and how I can customize the chart colors and layout.
Prompt 4
I want to extend the covid-19 tool to save each symptom check result to a CSV file. Help me add that feature to the existing Python code.
