What is a coronavirus, and what is COVID-19?

Coronaviruses are a large family of viruses. Not all coronaviruses are COVID-19. A novel (or new) coronavirus is a strain of virus that has not been previously identified in humans. COVID-19 is a type of novel coronavirus that is spreading from person to person in many countries and states, including Colorado.


How is COVID-19 spread?

COVID-19 spreads from person to person and is thought to be transmitted mainly through respiratory droplets produced when an infected person coughs or sneezes, similar to how influenza and other respiratory viruses spread.

It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes, but this is not thought to be the main way the virus spreads.


What are the symptoms of COVID-19?

Symptoms, especially early on, may be mild and feel like a common cold. Early symptoms could include a combination of cough, body aches, fatigue, and chest tightness. A fever may not appear until several days into the illness, and some people may never develop a fever throughout the duration of the illness. People who have symptoms should get tested and self-isolate.

More advanced symptoms include fever, cough, shortness of breath, or breathing difficulties, and more. These people also should get tested, self-isolate, and contact a medical provider as necessary. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure, and death.

There is no specific, evidence-based treatment for COVID-19 at this time, but there are studies involving promising treatments, such as the antiviral medication Remdesivir. Many of the symptoms can be treated, and therefore treatment is based on the patient’s clinical condition. Many people will be able to recover on their own. Scientists are reporting progress with clinical trials of an antiviral medication called Remdesivir, but trials are still in progress to find out whether this is a suitable and effective treatment.
