About COVID-19

Last updated: August 19, 2020

Our understanding of COVID-19 continues to evolve. Nationally, COVID-19 activity is still increasing.

SARS-CoV-2 is the name of the virus that causes coronavirus disease 2019 (COVID-19). The disease is believed to have originally occurred from animal-to-person contact, and it spreads person-to-person.

COVID-19 can be mild or severe, and it can affect anyone. However, older people with other health conditions seem to be at higher risk for severe illness and death.

Symptoms

Symptoms may appear two to 14 days after exposure to the virus. People with one or more of these symptoms may have COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

What to Do If You Feel Sick

Call your physician’s office for guidance about testing and treatment if you have symptoms of COVID-19. If you do not have a primary care physician, you may call the Northwestern Medicine COVID-19 Hotline at 312.47.COVID (312.472.6843) for guidance.
Do not go to your physician’s office before calling. You could risk infecting others.
If you are having serious trouble breathing, go to the emergency department or call 911.
