What is COVID-19?Updated 9-9-26
  • COVID-19 (coronavirus disease 2019) is a respiratory illness that primarily affects the lungs, but can affect all the organs of the body. It is caused by the SARS-CoV-2 virus.
  • Symptoms can be mild to severe. Some people may have no symptoms at all.
  • COVID-19 vaccines help protect you from severe disease, hospitalization, and death.
  • Protection from vaccines decreases over time so it is important to stay up to date with vaccines.

COVID-19: Symptoms
symptoms of COVID-19 graphic

Symptoms of COVID-19 can include fever/chills, cough, sore throat, runny nose or stuffy nose, body and head aches, and difficulty breathing. Some people may also experience nausea, vomiting, or diarrhea. Symptoms can range from mild to severe and usually appear 2-14 days after being in contact with the virus. Some people may not experience any symptoms, while others may experience symptoms for weeks or months, often referred to as “long COVID-19.”

COVID-19 symptoms can be very similar to the symptoms caused by other viruses such as Influenza or RSV. It may be difficult to determine if you have COVID-19 based on symptoms alone. If you think you have symptoms of COVID-19, talk to your doctor or healthcare provider about testing and/or treatment right away.

How does COVID-19 Spread?
COVID-19 graphic

COVID-19 spreads through droplets or tiny particles in the air from a person who has the virus. Other people can breathe in these droplets and particles, or the droplets can get in via the eyes, nose, or mouth.

To protect yourself and others from COVID-19 and other respiratory illnesses:

  1. Stay current on your COVID-19 immunizations to reduce your risk of severe illness.
  2. Take steps for cleaner air. Open windows, use fans and portable air cleaners, run heating and air to keep air circulating, and upgrade filters. Choose outdoor spaces for group activities when possible.
  3. Practice good everyday hygiene, like washing your hands and covering your coughs and sneezes.
  4. Consider wearing a mask, especially in crowded indoor settings, during fall and winter seasons.
  5. Stay home when you're sick.

For more information on how to stay healthy and what to do when you’re sick, visit the Respiratory Viruses webpage (LAC DPH).

Information for the Public
Vaccine Information
  • COVID-19 vaccines help your immune system build protection against COVID-19 without getting potentially very sick from COVID-19.
  • The virus that causes COVID-19 changes over time and protection from the vaccine decreases. Getting the updated COVID-19 vaccine each year helps protect you and others from severe illness.
