What is it?

Novel Coronavirus 2019 (COVID-2019) is a virus (more specifically, a coronavirus) identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China. Coronaviruses are a large family of viruses which cause respiratory illnesses. The common coronaviruses that infect humans cause symptoms of the common cold: low grade fever, cough, sneezing and a runny nose. The novel coronavirus 2019 is a new virus that we haven't seen before. Early in this outbreak, many of the patients in the outbreak in Wuhan, China reportedly had some link to a large seafood and animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets, indicating person-to-person spread is occurring. At this time, it’s unclear how easily this virus is spreading between people. 


For confirmed COVID-2019 infections, reported illnesses have ranged from people with little to no symptoms to people being severely ill and dying. Symptoms can include:

  • Fever
  • Cough
  • Shortness of breath


There is currently no vaccine to prevent COVID-19 infection. Transmission of infection is believed to be through contact with respiratory droplets, such as from a cough or sneeze, from an infected person. The best way to prevent infection is to avoid being exposed to this virus. The risk of novel coronavirus infection to our community is low. However, as a reminder, public health experts recommend everyday preventive actions to help prevent the spread of common respiratory viruses, such as the flu, including:

  • Wash your hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer that contains at least 60% alcohol if soap and water are not available.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Avoid close contact with people who are sick.
  • Stay home when you are sick.
  • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
  • Clean and disinfect frequently touched objects and surfaces.
