Symptoms and Basics

COVID-19 is a new disease, caused by a novel (or new) coronavirus that wasn’t previously seen in humans. Because it’s a new virus, scientists are learning more each day. Although most people who have COVID-19 have mild symptoms, COVID-19 can also cause severe illness and even death. Some groups, including older adults and people who have certain underlying medical conditions, are at increased risk of severe illness. Since the virus that causes COVID-19 is a newly identified strain of coronavirus, we still don’t know everything about the illness, but Health Alliance is keeping track of the latest details and recommendations from health officials like those at the CDC and state and local public health agencies.

People with COVID-19 have reported a wide range of symptoms – from mild symptoms to severe illness. Symptoms may appear two to 14 days after exposure to the virus. If you have fever, cough or other symptoms, you may have COVID-19.

• The best way to protect yourself and others is to quarantine by staying home for 14 days if you think you’ve been exposed to someone who has COVID-19. Check your local health department’s website for information about options in your area to possibly shorten this quarantine period.
• Be alert for symptoms of COVID-19.
• If possible, stay away from others, especially people who are at higher risk for getting very sick from COVID-19.
• You may NOT need to quarantine if:
• You have been fully vaccinated and have no symptoms.
• You were previously diagnosed with COVID-19 within the last three months and don’t develop any new symptoms.

As always, if you need emergency medical assistance, call 911.
