Corona symptoms: There are seven forms of Covid 19 disease

North Rhine-Westphalia – Since the end of January this year, that is Coronavirus in Germany. Meanwhile, more and more researchers are finding various properties of the Virus up. Researchers from Wien have now published a study on corona symptoms.

Covid-19: Researchers identify seven groups of symptoms

A disease with Covid-19 can trigger a variety of symptoms. They are common temperature, Sore throat and headache the first Symptomscomplaining of the sick. The loss of smell and taste is also particularly typical.

Like the researchers of the Medical University Wien have now discovered, with a mild course of Covid-19, the symptoms can be summarized in seven different groups. These groups a Symptoms Researchers are sure they should usually also appear together (all news about the corona virus in NRW in the live ticker at RUHR24.de).

Coronavirus infection: Covid-19 patients complain of symptoms of flu and a runny nose

In their study, the researchers looked at which immune cells and antibody ten weeks after being infected with Coronavirus they were still detectable in the patient’s body. In addition, a total of 109 ex People infected with Covid-19 with a mild course after his Symptoms questioned. Another control group consisted of 98 people who had not been infected.

“We were able to clearly identify the systemic and organ-specific forms of the primary Covid-19 disease delimit, “says study author Winfried Pickl. Consequently, the first group of symptoms is typical Symptoms a flu-like infection: fever, exhaustion e to cough. The second group is Symptoms a cold: sneezing, dry throat and nasal congestion.

A certain Covid-19 group is particularly common among young people

The third group is characterized by muscle and joint pain, the fourth by inflammation of the eyes and mucous membranes. The fifth group of symptoms would be over Lung problems suffer from pneumonia and shortness of breath. The sixth group of symptoms of Covid-19 would complain of serious gastrointestinal problems. These include diarrhea and nausea headache. Group seven, the last group of symptoms, complains of loss of smell and taste.

The researchers were able to make surprising discoveries about this group of symptoms: “In the latter group, we were able to see that more people with a young immune system“, measured by the number of T lymphocytes that have recently migrated from the thymus are affected”, explains Winfried Pickl in the results of she studies.

Vienna researchers are uncovering Covid 19 disease and its long-term consequences

But not only that Symptoms can be divided into several groups, but also the long-term immunological consequences of a Covid-19 disease. Sars-CoV-2 virus is said to be present immune system and leaves a kind of imprint in the blood. The white ones Blood cells, which are actually supposed to fight bacterial pathogens, are much lower than usual in Covid patients. On the contrary, among other things, multiply Memory cells forte, intended to kill virus-infected cells.

But the Vienna researchers were also able to find out a lot about the amount of antibodies. So stands the fever level and the amount of antibody related to each other: the higher the fever, the more antibodies can be found in the study subjects. “This shows that this immune system He is still coping intensely with the disease several weeks after the first infection, ”explains Pickl.

This finding could also explain some of the long-term effects of Covid-19 disease, such as fatigue or heart problems. However, more research is needed to fully understand the virus. The researchers’ study Wien but it should also be possible vaccine can help, “because we can now rely on promising biomarkers and perform even better monitoring,” he says. The study was published in the journal European Journal of Allergy and Immunology released.
