For what situations are there quarantine recommendations for exposure to a case?

If you have been told by a public health professional or other authority that you are a close contact of a laboratory confirmed case of COVID-19, you must quarantine yourself for 14 days after your last contact with the case. You are considered a close contact if you have been directly within 6 feet of someone with a laboratory confirmed case of COVID-19 for 10 minutes or more.

People who work in healthcare, public health, law enforcement and the meat packing industry may be allowed a modified quarantine, which allows them to continue working during their 14-day quarantine period while wearing appropriate Personal Protective Equipment (PPE), as long as they remain symptom free. The decision to allow a modified quarantine is made by the local health officer. 

Employees who were potentially exposed to COVID-19 due to exposure to a case should monitor for signs and symptoms of COVID-19, including checking for a fever of 100.4 (F) or higher at least twice per day and monitoring for lower respiratory symptoms including cough or shortness of breath. Use this symptoms log. If symptoms develop during the 14-day quarantine period, employees should stop work immediately and notify their employer and public health.
