Pseudo COVID19 detector project

Hi, i have made a tutorial about COVID19 Detector.
i know it's not perfect and definitely need more work to truly detect covid19
but i think it may give inspiration.
The main problem in this project is:
You can detect : common cold, fever etc.. but those are just symptoms for covid19 and a person can have those without having covid19. unfortunately i couldn't unique covid19 from other "diseases"
