The time between exposure to the COVID-19 virus and onset of symptoms is called the “incubation period.” The incubation period for COVID-19 is typically 2 to 14 days, although in some cases it may be longer.

If you are returning from an area with an outbreak of COVID-19 the CDC is recommending you self-quarantine for 14 days immediately upon returning from your travels, even if asymptomatic. If you develop a fever and symptoms of respiratory illness, such as cough or shortness of breath during those 14 days contact your health care professional and mention your recent travel. Your provider will work with your county public health department to determine if you need to be tested for COVID-19. If you have had close contact with someone showing these symptoms who has recently traveled from an impacted area, you should call a health care professional and mention your close contact and their recent travel.

Your healthcare professional will work with your county health department to determine if you need to be tested for COVID-19.

A person who is tested will have three specimens taken: oral, nasal, and saliva. The samples will be given to the county health department, who will then either ship or deliver them to the closest state laboratory. If a specimen is tested positive, it will be identified as ‘presumptive positive’ until the result is confirmed at the Centers for Disease Control and Prevention (CDC).

There is no specific antiviral treatment recommended for COVID-19 infection. People infected with COVID-19 should receive supportive care to help relieve symptoms.
