Hello and welcome to Ask A Doctor service.
I have reviewed your query and here is my advice.
As per the COVID-19 related quarantine guidelines by CDC and due to your recent exposure to people with COVID-19, it is advised for you to quarantine yourself starting from date you had close contact with COVID-19 positive patient and until 15 days thereafter. If your most recent contact was 10 days ago, then your quarantine period will last for 5 more days. I am also attaching the link of CDC guidelines for reference.
