From the Chronicle: Thank you, H-F!

Illinois and Chicago public health officials announced Friday the discovery of the first case in Illinois of the SARS-CoV-2 variant B.1.1.7, first identified in the United Kingdom. The case was identified by the Northwestern University Feinberg School of Medicine through sequencing analysis of a specimen from bio-banked samples of COVID-19 positive tests.

A follow-up case investigation found that the individual had travelled to the UK and the Middle East in the 14 days prior to the diagnosis. CDPH has worked to identify close contacts of the individual to reinforce the importance of adherence with quarantine and isolation measures.

The new strain was first identified in the United States about two weeks ago in Colorado and has since been identified in several other states. Evidence suggests that this variant can spread more easily than most currently-circulating strains of COVID-19, but there is no evidence that the new strain affects the sensitivity of diagnostic tests or that it causes more severe illness or increased risk of death. 

In addition, data suggest current vaccines will be effective and safe in providing protection against the variant.

“This news isn’t surprising and doesn’t change our guidance around COVID-19. We must double down on the recommended safety strategies we know help stop the spread of this virus,” said Chicago Department of Public Health Commissioner Dr. Allison Arwady. 

“When we learned of this and other COVID-19 variants, we increased our surveillance efforts by performing genomic sequence testing on an increased number of specimens,” said Dr. Ngozi Ezike, director of the Illinois Department of Public Health. 

The COVID-19 virus – also known as SARS-CoV-2 – like other viruses, constantly changes through mutation, and new variants of a virus are expected to occur over time. 

According to the CDC, this variant is estimated to have first emerged in the UK during September 2020. Other novel variants of SARS-CoV-2, which also might change the way the virus transmits or behaves, have been identified in South Africa, Nigeria, Brazil, Japan and the US. More novel strains are likely to be identified in the coming weeks and months.

As a pre-cautionary measure, the CDC earlier this week announced that all international passengers headed to the United States will first need to show proof of a negative coronavirus test, a policy which goes into effect on Jan. 26. 

The new policy requires all air passengers, regardless of vaccination status, to get a test for current infection within the three days before their flight to the United States departs, and to provide written documentation of their test results or proof of having recovered from Covid-19.

Everyday preventive actions by the public can help to slow the spread of all known COVID-19 variants, including wearing a mask, washing hands often, staying six feet away from others and avoiding crowds, avoiding non-essential travel and getting vaccinated when it is your turn.
