About Coronavirus:

  • Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV).
  • Coronaviruses are zoonotic, meaning they are transmitted between animals and people.

Symptoms:

Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

Transmission:

Human coronaviruses most commonly spread from an infected person to others through:

  1. the air by coughing and sneezing.
  2. close personal contact, such as touching or shaking hands.
  3. touching an object or surface with the virus on it, then touching your mouth, nose, or eyes before washing your hands.
  4. rarely, fecal contamination.
