COVID-19 Latest Updates and Resources

How does the COVID-19 virus spread?

Per the CDC, the current understanding of spread is based on what they know about similar coronaviruses:

  • Person-to-person spread in close contact (within about 6 feet)
  • Respiratory droplets produced by a cough or sneeze and then introduced to another person through mouth, nose or inhaling droplets
  • Possibility of spreading through indirect contact by touching an object that has been contaminated with the coronavirus and then touching their mouth, nose or possibly their eyes (not considered to be the main way of spreading)
  • Infected persons are thought to be most contagious when they are most symptomatic
  • Possibility there could be some spread prior to exhibiting symptoms (again not considered to be the main way of spreading)
  • Nosocomial spread among healthcare workers and patients has been reported

All Curi recommendations are based on current CDC criteria at the time of publication. CDC guidance for SARS-CoV-2 infection may, or may not, be adopted by state and local health departments to respond to rapidly changing local circumstances. Providers should always check with their local health department to see if the CDC’s guidance on any given topic has been modified (particularly if more restrictive) from the CDC’s recommended guidelines. Follow this link https://www.cdc.gov/publichealthgateway/healthdirectories/index.html for contact information to your state/local health department. If local recommendations vary from those of the CDC, and you are unsure what recommendations to follow, then it is safer to follow the more restrictive guidelines/recommendations.
