Colorado confirms it has detected first cases of ‘mutant COVID’ strain  

Colorado has announced it has detected the first US case of the super-COVID strain that was first found in the UK.

Governor Jared Polis revealed the worrying news in a tweet, writing: ‘Today we discovered Colorado’s first case of the COVID-19 variant B.1.1.7, the same variant discovered in the UK. The health and safety of Coloradans is our top priority and we will monitor this case, as well as all COVID-19 indicators, very closely.’

An attached statement said the Colorado State Laboratory confirmed the case and notified the Center for Disease Control (CDC).

The strain – which is thought to be 70 per cent more infectious – was detected in a man in his 20s who is ‘currently in isolation in Elbert County and has no travel history.’ 

It is not believed that B.1.1.7 leads to more severe cases, and higher mortality rates have not been reported.

‘At this time, there is no evidence that this variant causes more severe illness or increased risk of death,’ the CDC stated on their website.

The fact the man has not traveled tells officials he caught the strain from someone else in the US.  

The man will remain in isolation until he is cleared by health officials. 

The statement adds: ‘The individual has no close contacts identified so far, but public health officials are working to identify other potential cases and contacts through thorough contact tracing interviews.’

Polis said: ‘There is a lot we don’t know about this new COVID-19 variant, but scientists in the United Kingdom are warning the world that it is significantly more contagious.

‘The health and safety of Coloradans is our top priority and we will closely monitor the case, as well as all COVID-19 indicators very closely. 

‘We are working to prevent spread and contain the virus at all levels.’ 

The news comes after millions of people traveled across the US to see loved-ones during the holidays. 

As of Tuesday there were 19.5 million confirmed COVID-19 cases in the US, and 337,210 deaths. 

The new variant of the coronavirus was first identified in November and has been spreading rapidly in Britain, with huge swathes of England being placed under its strictest COVID-19 restrictions.

The mutation known as the B.1.1.7 lineage may be up to 70 per cent more infectious and more of a concern for children.

It reportedly accounts for 60 per cent of recent infections in London.

It has sown chaos in Britain, prompting a wave of travel bans that are disrupting trade with Europe and threatening to further isolate the island country.

It has also been detected in France, Spain, Denmark, Italy, Sweden, Iceland, Singapore, Australia and Japan.

Japan on Monday barred entry to any foreign nationals. This will be in effect until the end of January. 

Polis urged people to continue to wear masks, stand six feet apart when gathering with others and only interact with members of their immediate household. 

His announcement was made on the same day Dr Anthony Fauci reiterated concerns about the new strain of coronavirus which he correctly predicted had already arrived in the US. 

‘I cannot imagine that we’re not going to get it,’ Fauci said of the new strain. 

‘The question is preventing it from becoming the dominant strain.’

Officials so far believe that coronavirus vaccines will work against the new strain.

The CDC explains that the new COVID-19 variant has a mutation in the receptor binding domain (RBD) of the spike protein at position 501, where amino acid asparagine (N) has been replaced with tyrosine (Y). 

Coronaviruses mutate regularly, acquiring about one new mutation in its genome every two weeks. 

Many mutations are described as being ‘silent’ because they do not change the structure of the proteins they encode, and produce a three-letter codon that translates to the same amino acid. These mutations are known as ‘synonymous’.

Other mutations may change the codon in a way that leads to an amino acid change. and these are known as ‘non-synonymous’ mutations, but this amino acid substitution does not impact the protein’s function.

B.1.1.7 has 14 non-synonymous mutations, six synonymous, and three deletions, the CDC says. 

What is the ‘mutant COVID strain’ and why are experts concerned?

Coronaviruses mutate regularly, acquiring about one new mutation in its genome every two weeks. 

Most mutations do not significantly change the way the virus acts.

This super strain, named B.1.1.7, was first identified in the UK in November.

It has since been found in France, Spain, Italy, Iceland, Japan, Singapore, Australia and now the United States. 

The new COVID-19 variant has a mutation in the receptor binding domain (RBD) of the spike protein at position 501, where amino acid asparagine (N) has been replaced with tyrosine (Y). 

It is more infectious than previous strains and potentially more harmful to children.
