Am I at risk from the Omicron variant and other COVID-19 variants?

Am I at risk from COVID-19 variants in Connecticut?  

According to the CDC, your risk for being affected by COVID-19 variants is higher if you are unvaccinated. This includes the Omicron variant which continues to be the leading variant in the United States. Your risk for getting Omicron is much less if you are vaccinated. 

However, if you are current with your vaccines, your chance of becoming severely ill is greatly reduced. 

Omicron Subvariants

All variants, including Omicron have subvariants (i.e., lineages and sub-lineages). The most common omicron subvariants include:

  • BA.1
  • BA.1.1
  • BA.2
Omicron Transmission

Omicron transmits COVID faster than earlier variants like Delta. According to the CDC, anyone infected with Omicron can transmit the virus to others. This is still true even if they are vaccinated (i.e., breakthrough infections) or do not have symptoms. 

Stay Up to Date with Your Vaccines

Staying on top of your vaccinations, boosters and additional doses (if needed) is our number one defense against COVID-19, Omicron and variants. 

According to the CDC, vaccines help reduce the chance of new variants developing. 

They recommended getting vaccinated for those age 5 and up. The CDC also recommends boosters for individuals 12 and up. 

COVID-19 variants in our state are being closely monitored by the relevant authorities. If you are in a vulnerable group, it is recommended that you continue to wear a mask, particularly indoors. Unvaccinated persons are at greater risk than those who are vaccinated, so getting your shots is critical to lowering your risk of infection by a COVID-19 variant.

Do Monoclonal Antibodies Work?

According to the CDC, scientists are looking at the effectiveness of monoclonal antibody treatments. They are finding that their effectiveness depends on the subvariant. Some are effective against omicron. Others are effective against BA.1 and BA.1.1, but less so with BA.2,

Getting Tested

Be sure to get tested if you suspect you have COVID-19 (i.e., have symptoms or were exposed). Approved test options include:

1. NAAT's (nucleic acid amplification tests)

2. antigen tests

3. self-tests

If you need help to decide on which test to choose, use the CDC's COVID-19 testing tool.


Currently, several COVID-19 variants are being tracked in CT.  

The CDC and WHO are working to track the rate of variants and document the proportions of SARS-Cov-2 lineages emerging across the US at 2-week intervals.
