The highly contagious omicron variant of the coronavirus has been sweeping the country – though some states have been impacted more than others. 

As cases continue to rise nationwide, thousands of flights have been canceled as an increased number of airline workers have tested positive, and other Americans have been waiting hours at testing sites. 

The Centers for Disease Control and Prevention (CDC) recently cut down the recommended isolation time for those who test positive but show no symptoms from 10 days to just five – though it’s unclear if the agency will amend its advice to recommend a negative test for those wishing to leave quarantine early. CDC Director Dr. Rochelle Walensky said last week that a PCR test after infection can be positive for up to 12 weeks. 

FAUCI TEASES NEW TESTING RECOMMENDATION DESPITE SHORTAGES 

As schools are looking to resume after holiday breaks, testing woes could further impact students' and teachers’ return. And omicron's effect is being felt across other industries as more workers call out sick. 

The Biden administration warned Americans might have to wait weeks for the rollout of promised at-home tests, and results for PCR tests have been delayed by days in some areas. 

Here's a look into how omicron is affecting each state – and Washington, D.C. – listing the states by the most to the least number of cases recorded by the CDC over the last week per every 100,000 people.
