If your worker is fully vaccinated or has had COVID-19 in the last 90 days, they are not required to self-isolate and can continue to participate in routine activities, such as work or school, as long as they do not have any symptoms.
Those who are NOT fully vaccinated are required to self-isolate for 10 days from the day they last had contact with the person who has COVID-19, even if they do not have symptoms.
