The National Institute for Health and Welfare (THL) published 9.2 different model versions, in which it said that the British virus variant would become the main virus in Finland in about three months, ie in May.
In two weeks, the British variant has increased the proportion of viral infections at a brisk pace.
It is now already a mainstream virus in the Hus region.
Asko Järvinen, chief physician of infectious diseases at Hus, hits the worm figures on the table:
- In the Hus area, the share of the British variant has risen from about 10 per cent to almost 65 per cent in four weeks, Järvinen states.
The British variant has been considered the so-called wild-type virus, i.e. the original virus from Wuhan, China, to be generally more alert in terms of both infectivity and symptoms.
- Yes, the British variant is a more severe disease in terms of symptoms, it is shown by several British studies, Järvinen states and justifies the fact that those who have received the variant in question are more sensitive to hospital treatment.
The symptom picture of the British variant may also differ from the symptoms of the wild virus.
According to a British study, common coronavirus symptoms such as cough, muscle aches, fatigue and sore throat were more common in those with the British variant than in those with the wild-type virus.
In the study, on the other hand, those with a British variant did not lose their sense of smell and taste as often.
The survey was conducted on British patients who had a positive result in November – January.
The investigation was previously reported by The Guardian.
However, Järvinen stumbles on drawing too many conclusions about individual symptoms and wants to make one thing clear:
- There is no single symptom that can identify the cause of the disease.
Whether it was a common flu or a coronavirus.
- If the morning coffee does not taste or smells, then it does not yet tell you that it is precisely the coronavirus.
Järvinen has two clear views on why the British variant is rampant at the moment.
- On average, the virus levels are higher in this variant, ie in practice there is more of that virus in the nasal mucosa and airways.
- And when such a person coughs, then comes out drops with more of that virus, he continues.
Another significant reason for infectivity is that the so-called spike protein of the virus is more sensitive to the surface of the airway mucosa.
Järvinen says that it can be compared to a ladder used in darts, where a spike or virus sticks to the surface of the airway mucous membranes.
The virus variants in South Africa and Brazil have the same mutation in the spike protein, which, according to the chief physician, may also explain their higher infectivity.
