The delta variant dominates the headlines because of its increased risk of infection. A certain symptom is supposed to indicate the new type.
Munich – It is much more contagious than the original variant and is now determining the pandemic in Germany. In Munich, the Delta variant is said to have increased almost fivefold in June – at least. As is now known, the delta mutation manifests itself with very specific symptoms. These differ from the original type.
With the first Corona variant, the most common symptoms quickly became important general knowledge: dry cough, loss of smell and taste, headache and fever set the alarm bells ringing. But meanwhile other signs can also point to Corona.
Runny nose as a symptom of corona
According to data from Great Britain, for example, the list is being expanded to include a specific symptom. A runny nose should also indicate Covid-19. Well-known indicators such as sore throat and headache, fever and cough should still be taken into account.
The findings were brought about by the study “Zoe Covid Symptom” under the direction of epidemiologist Prof. Tim Spector. According to its own information, the study is the most extensive corona study worldwide. According to Specter, Delta is more “like a bad cold”.
So far, a loss of the sense of taste has been a reliable indicator of corona. However, Spector no longer places this symptom in the top 20.
Top symptoms according to the “Zoe Covid Symptom” list has changed
How quickly this is changing can be seen from your own assessments of the study. The new top 4 symptoms according to “Zoe Covid Symptom” look like this:
Symptoms with two vaccinations:
2. Runny nose
4. Sore throat
Symptoms of vaccination:
1. Sore throat
2. Runny nose
3. Sore throat
5. Persistent cough
Symptoms without vaccination:
2. Sore throat
3. Runny nose
5. Persistent cough
How quickly this is changing can be seen in the top 21 that the study published at the end of March: The top symptoms of today (sore throat, headache, runny nose) did not appear in the top 5 at the time.
1.High temperature (fever)
3. Persistent cough
4. Loss of smell
5. Loss of taste
8. Sore throat
9. Confusion, especially among older citizens
11. Changes in the tongue area
12. Red fingers or toes
13. Shortness of breath
14. Chest pain
15. Muscle pain
18. Loss of appetite
19. Abdominal pain
20. Runny nose
Changes in symptoms at Delta: “Virus has adapted to humans”
Compared to the picture explains epidemiologist Klaus Stöhr explains the changed symptoms: “It is biologically plausible that the virus has continued to adapt to humans. For example, the upper respiratory tract is now also affected more and the reproduction begins right away in the nasal and throat mucous membranes. This will probably lead to the more frequent coughs, runny nose and sore throat. ”However, Stöhr also warns that causal studies have not yet been published -“ the observations have yet to be confirmed. ”
Do you have to have a corona test every time you have a cold?
Whether you have to have the corona test every time you have a cold, Stöhr answers as follows: “If I have not been vaccinated or have recovered, then I should definitely consider a corona infection during this time of the pandemic. So it would be sensible to do a quick test so that in an emergency I can isolate myself for the protection of myself and others. “
But you cannot be sure that you have the Delta variant, says the scientist: “There are simply too many different respiratory diseases that produce similar symptoms. Clinical diagnosis based on such symptoms is currently insufficient. If you have a cough, runny nose, etc. you should always think of Corona at present if you have not been vaccinated or have recovered. ” (cg)
Politicians are worried about the spreading delta variant of Corona. The first scientists give the all-clear: Delta is more contagious, but not more dangerous. Others are more careful.
