In recent days we have just discovered a covid variant called XE omicron.
This is said to be a 'mutant' variant as it's thought that both the original omicron strain and it's 'stealth' sub-variant have combined to make a new one.
Many cases have been detected in the UK though it's not clear how much - or if any - have spread to Scotland.

The news of the variant comes not long after Scotland relaxed its covid restrictions.
However whilst many are thinking about covid, others are said to be getting sick over something called the rhinovirus and now a warning over symptoms has come after the Department of Health asked people who are experiencing the symptoms of a rhinovirus to stay home and isolate - even if they have tested negative for covid.
According to Belfast Live, those with untreated asthma, COPD or an impaired immunity are most at risk of becoming sick from this, a Belfast respiratory expert has said.
And now a leading respiratory physician at the Belfast Trust, Dr Joe Kidney, has outlined those who are most at risk of become sick as a result of a rhinovirus which usually develops in people as a common cold.
Dr Kidney said that most people who are infected with a rhinovirus only experience the symptoms of a cold however for asthmatics, those with COPD or an impaired immune system, the risks are higher.
Speaking to Belfast Live, Dr Kidney said: "I think we all get about six colds a year under normal circumstances and our bodies might have forgotten that during the lockdown.
"The majority of those are rhinovirus and there are around 12% of us that have a rhinovirus in our nose at any one time and they like to replicate in colder temperatures such as 32 degrees rather than 37, which is our body temperature. So when it gets cold outside it replicates in our nose which is why we call them colds.
"Most of the symptoms are of a cold, cough, runny nose, sinusitis and they can make you feel just rotten but often not very very ill, where flu is much more likely to give you temperatures. Although you can still get aches and pains with rhinovirus as well.
"The issue is now we are looking at people with runny noses and we want to know if they have coronavirus and the answer is they might do, but with a runny nose that can actually be a rhinovirus as well."
He continued to explain: "Poorly controlled asthmatics are a real risk group and these are people who should be taking preventer treatments, a brown or red inhaler. They feel well between the episodes so they feel an the urgency to take medication because they are getting by with their relievers or blue inhalers, and then they can get very sick with a rhinovirus infection, so probably rhinovirus is responsible for 80% of asthma exacerbations and while it is very uncommon now, asthma deaths do occur.
"What I used to say is the common cold can be uncommonly dangerous to some people. The other that gets very sick are those with COPD, and an exacerbation is the second commonest cause for people coming into hospital."
Speaking about the covid vaccine, the doctor said that the vaccine has been a "huge achievement and success" adding it's "one of the greatest victories of science in this century."
He added: "We had a lot of new treatments pioneered at the Mater, the covid hospital for Belfast. Lots of patients took part and we tried about 11 drugs, four of which are now in use and it substantially changed how we do things.
"It was a real roll up your sleeves and get this job done effort and people were remarkable. It was great to see that collectively we could find the new treatments and see them rolled out right in front of our eyes, it was great to make that change.
"My colleagues, particularly my nursing colleagues, have really contributed to the success. Now we have different populations but we don’t have the same affluence as parts of England and despite that we had a low mortality. If we had English mortality rates we would have had 5,000 deaths, not 3,000, but we really rolled up our sleeves and tried to make sure everyone go the best treatment."
The doctor concluded with a final warning about the rhinovirus stating that people at risk need to take caution.
He said: "We have been getting them for years and if you are healthy you will get a cold but if you are susceptible it could make you sicker.
"People with asthma need to take their preventers, they could be between infections and they could get sick with a rhinovirus and COPD often lands people in hospital. It is best not to get them if you are vulnerable. I Worry about older people taking care of young people, it can be a great spreader of these colds."
