The Reno County Health Department's case investigation team works with COVID-19 positive individuals, schools, and employers to determine who is a "close contact." Case investigators inform close contacts if they need to quarantine to help reduce the spread of COVID-19.
Generally speaking, you are a close contact if any of the following situations happened while you spent time with a person with COVID-19, even if they don't have symptoms:
You were within 6 feet of someone who has COVID-19 for a total of 10 minutes or more
You provided care at home to someone who is sick with COVID-19
You had direct physical contact with the person (ex: hugged or kissed them)
You shared food or drink with the person
They sneezed, coughed, or somehow got respiratory droplets on you
In reality, situations are not clear cut, so the Reno County Health Department's case investigation team will evaluate your specific scenario and inform you if you are a close contact.
