The Los Angeles County Department of Public Health Isolation Order states that all individuals who have been diagnosed with or who are likely to have COVID-19 must isolate themselves in their home.
If you had symptoms, you must stay home until:
- At least 10 days have passed since your symptoms first started and
- You have had no fever for at least 24 hours (without the use of medicine that reduces fevers) and
- Your symptoms have improved (for example, cough or shortness of breath)
If you tested positive for COVID-19 but never had any symptoms:
- You must stay home for 10 days after the test was taken, but
- If you develop symptoms, you need to follow the instructions above
The Los Angeles County Department of Public Health Quarantine Order states that all close contacts of a person diagnosed with or likely to have COVID-19 while that person was symptomatic must quarantine themselves for 14 days. People are considered infectious 48 hours before the start of their symptoms until their isolation period ends. View the home quarantine guidance for close contacts to COVID-19.
Who is considered a close contact? According to the Centers for Disease Control and Prevention, a close contact is someone who was within 6 feet of an infected person for a cumulative total of 15 minutes or more over a 24-hour period* starting from 2 days before illness onset (or, for asymptomatic patients, 2 days prior to test specimen collection) until the time the patient is isolated.
* Individual exposures added together over a 24-hour period (e.g., three 5-minute exposures for a total of 15 minutes). Data are limited, making it difficult to precisely define “close contact;” however, 15 cumulative minutes of exposure at a distance of 6 feet or less can be used as an operational definition for contact investigation. Factors to consider when defining close contact include proximity (closer distance likely increases exposure risk), the duration of exposure (longer exposure time likely increases exposure risk), whether the infected individual has symptoms (the period around onset of symptoms is associated with the highest levels of viral shedding), if the infected person was likely to generate respiratory aerosols (e.g., was coughing, singing, shouting), and other environmental factors (crowding, adequacy of ventilation, whether exposure was indoors or outdoors).
A patient with presumed or confirmed COVID-19 is considered to be infectious from 48 hours before their symptoms started until their isolation period ends. Asymptomatic patients with laboratory-confirmed COVID-19 infection are considered to be infectious from 48 hours before their test was taken until 10 days after their test was taken.
