Confirmed Positive & Probable Cases: The Oakland County Health Division defines a confirmed case as a positive result from a PCR COVID-19 Test and a probable case as a positive rapid test. 

Contact Tracing: A strategy for slowing the spread of disease in which public health workers communicate with infectious people to identify their contacts. They then follow up with those contacts to provide guidance on how to quarantine themselves and what to do if they develop symptoms of disease.

Quarantine: The practice of keeping someone who might have been exposed to COVID-19 away from others. Quarantine helps prevent spread of disease that can occur before a person knows they are sick or if they are infected with the virus without feeling symptoms. People in quarantine must stay home (usually 10 days), separate themselves from others, monitor their health, and follow directions from their state or local health department.

Isolation: The practice of separating people infected with the virus (those who are sick with COVID-19 and those with no symptoms) from people who are not infected. People who are in isolation (usually for 10 days) must stay home until it’s safe for them to be around others. In the home, anyone sick or infected must separate themselves from others by staying in a specific “sick room” or area and using a separate bathroom
(if available).

Close Contact: A person who was within 6 feet of a person infected with COVID-19 for more than 15 minutes with or without a mask. Examples of close contacts include individuals who were close to a person who is infected with COVID-19 by providing care to them at home, sharing a living space, having direct physical contact with them (touched, hugged or kissed them), and sharing eating or drinking utensils. People may also be close contacts if they were somehow exposed to droplets from an infected person (sneezed or coughed on).
