what is the general rule of thumb for a person to be around others?

CDC

I think or know I had COVID-19, and I had symptoms
You can be around others after:

• 10 days since symptoms first appeared and
• 24 hours with no fever without the use of fever-reducing medications and
• Other symptoms of COVID-19 are improving*

*Loss of taste and smell may persist for weeks or months after recovery and need not delay the end of isolation
Most people do not require testing to decide when they can be around others; however, if your healthcare provider recommends testing, they will let you know when you can resume being around others based on your test results.

I tested positive for COVID-19 but had no symptoms
If you continue to have no symptoms, you can be with others after 10 days have passed since you had a positive viral test for COVID-19. Most people do not require testing to decide when they can be around others; however, if your healthcare provider recommends testing, they will let you know when you can resume being around others based on your test results.
If you develop symptoms after testing positive, follow the guidance above for "I think or know I had COVID-19, and I had symptoms."

10 days asymptotic, you're golden.
