COVID-19 Variants


Variants are Common

When a virus is widely spreading in the community and causing infections, it is more likely to mutate or change. A virus that has changed or mutated is called a variant. 

Changes to the virus are usually harmless. However, sometimes the changes are more concerning. Changes could make the virus:

  • easier to spread from one person to another
  • cause more severe illness
  • less treatable with the current treatments
  • less responsive to the vaccines, making it less effective

 Scientists and public health experts are studying the COVID-19 variants to learn more.  

Stopping the Spread of the Virus is Key to Stopping New Variants from Circulating

Slowing down the spread of COVID-19 is key to lowering the chance that new variants will develop. The best ways to prevent the spread of any COVID-19 virus remain the same: 

  • Practice Safe Six: stay 6 feet apart, wear a mask, wash your hands, be extra safe if you are higher risk, stay home if sick, get tested if you have symptoms. 
  • Register today to get your vaccine.

New forms, or variants, that cause COVID-19 are circulating around the world and in Colorado. If you were to test positive for COVID-19 today, it’s more likely that you were exposed to a variant strain. Several seem to spread more easily and are of concern:

  • B.1.617  (often called the India Variant)   
  • B.1.17 (often called the UK Variant)
  • B.1.351 (often called the South Africa Variant)
  • P.1 (often called the Brazil Variant)
  • B.1.427 and B.1.429 (often called the California Variants) 

Current data shows the COVID-19 vaccines should work against current variants. Along with getting the vaccine as soon as one becomes available to you, continue to be safe by wearing masks and social distancing in public places, and avoiding large crowds.


Colorado is Testing and Monitoring for Variants

Testing is being done through the Colorado Department of Health and Environment to find variants in Colorado. Contact tracing is then conducted to help stop the spread of the new variant in the community it is located in. 

COVID-19 Vaccines May Work Against Some Variants

The currently authorized COVID-19 vaccines are effective at reducing or preventing serious illness and death caused by COVID-19. Research is underway to determine the level of protection the current vaccines have on new variants.
