The new Omicron variant shed more light on the symptoms linked to the coronavirus infection. First, doctors from South Africa started noticing symptoms different from the original three Covid signs. Then a review of data from patients collected by the ZOE COVID Study app added to this new symptom knowledge. Different Covid symptoms still keep appearing.
The best-known symptoms of coronavirus remain cough, fever and loss or change to taste and smell.
The appearance of Omicron has seen calls for expanding this list as new symptoms of the Covid infection have been emerging.
The latest report from Berlin, Germany, has identified yet another COVID-19 symptom.
According to the newspaper called Ärztezeitung, the new Covid sign is fainting spells.
Fainting describes a temporary loss of consciousness and muscle control, the Cleveland Clinic states.
This is usually caused by low blood flow to the brain.
However, doctors in a Berlin hospital have found fainting spells to be linked to Covid infection in a 35-year-old.
The 35-year-old had to visit the emergency department because of recurring fainting spells.
It seems that coronavirus triggered fainting, also known as syncope, in this case.
According to the German newspaper, the doctors see “a clear connection” between Covid and the fainting spells.
They believe this arises for three reasons: the reproducible circumstances “under which the syncope manifests itself”, “the clear chronological correlation of the symptoms with a SARS-CoV-2 infection”; and the “absence of properties that indicate a structural heart disease”.
This new symptom adds to the growing evidence reporting on other than respiratory signs caused by the virus.
It could also be further confirmed based on the earlier reports of similar phenomena, according to the doctors.
For instance, the same symptom was also apparent in long-Covid patients.
And research from Italy, Spain and Portugal conducted 37 studies with over 14,000 Covid patients and found that in 4.2 percent of those examined, fainting or the feeling of impending unconsciousness was spotted in the early stages of the infection.
It seems that people over the age of 60 are particularly affected by fainting.
However, fainting spells weren’t classified as a typical Covid symptom, according to the researchers.
They stressed that when it occurs, it should be taken seriously and could be an “early warning sign”.
The researchers suspect that high blood pressure and antihypertensive drugs might play a role in this.
As well as other diseases, including diabetes, obesity, dyslipidaemia and heart disease.
