Symptoms of coronavirus 

At this time there is no vaccine for COVID-19, according to the CDC.

The symptoms of COVID-19 are similar to the flu or a bad cold. Symptoms include fever, cough and shortness of breath, according to the CDC. The virus is spread person-to-person.  

According to the CDC, spread is happening mainly between people who are in close contact (within 6 feet) of each other via respiratory droplets produced when an infected person coughs or sneezes. 

The droplets land on the noses and mouths of other people, who then inhale them.  

The CDC says it may be possible for the virus to spread by touching a surface or object with the virus and then a person touching their mouth, nose or eyes, but this is not thought to be the main method of spread.  

As the virus was discovered just a few months ago, more research is required to learn more about the spread pattern of the virus. 

Health experts recommend taking the following preventative actions:

  • Avoid close contact with people who are sick.
  • Avoid touching your eyes, nose, and mouth.
  • 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 using a regular household cleaning spray or wipe.
  • Follow CDC’s recommendations for using a facemask.
  • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
  • If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty.
  • Consult CDC’s travel website for any travel advisories and steps to protect yourself if you plan to travel outside of the US
