Coronaviruses are a large family of viruses. They can cause illness ranging from mild symptoms, like the common cold, to more severe illness such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS-CoV). COVID-19 is a new disease caused by a strain of coronavirus that has not been previously identified in humans.

 

 

How it's transmitted


Human coronaviruses cause infections of the nose, throat and lungs. They are most commonly spread from an infected person through:

  • respiratory droplets that are spread when you cough or sneeze
  • close personal contact, such as touching or shaking hands
  • touching something with the virus on it, then touching your mouth, nose or eyes before washing your hands

 

 

Symptoms

 

Those who are infected with COVID-19 may have little to no symptoms. You may not know you have symptoms of COVID-19 because they are similar to a cold or flu.

Symptoms may take up to 14 days to appear after exposure to COVID-19.

Symptoms have included:

  • Fever above 38 degrees Celsius
  • A new cough, or worsening chronic cough
  • Sore throat
  • Runny nose
  • Headache
  • A new onset of fatigue
  • A new onset of muscle pain
  • Diarrhea
  • Loss of sense of taste
  • Loss of sense of smell
  • In children, purple markings on the fingers and toes
  • Difficulty breathing
  • Pneumonia

In severe cases, infection can lead to death.

 

 

Treatment


At this time, there is no vaccine to protect against COVID-19.

Most people with mild illness will recover on their own. Your health care provider may recommend treatment or steps you can take to relieve symptoms. For those with more severe illness, hospitalization may be required.
