The research, conducted by scientists at the Medical University of Vienna, Austria, involved 109 patients recovered from Covid-19 and 98 healthy individuals in the control group.
In a study, published this Saturday in the journal Allergy, scientists say there are seven “forms of disease” in mild Covid-19, and that the new coronavirus leaves significant changes in the immune system even 10 weeks after infection. These findings may assist in the treatment of patients, and the development of a vaccine.
The research, conducted by scientists at the Medical University of Vienna, Austria, involved 109 patients recovered from Covid-19 and 98 healthy individuals in the control group and detected the following symptoms related to the disease:
Flu-like symptoms (such as fever, chills, fatigue, and cough);
Symptoms similar to the common cold (such as rhinitis, sneezing, dry throat, and nasal congestion);
Joint and muscle pain;
Inflammation of the eye and mucosa;
Lung problems (pneumonia and shortness of breath);
Gastrointestinal disorders (including diarrhea, nausea, and headache);
Loss of smell and taste.
According to immunologist Winfried F. Pickl, the study’s leader, symptoms related to loss of smell and taste affect predominantly individuals with a young immune system.
Along with this discovery, the scientists concluded that the new coronavirus significantly changes the blood of infected people, acting as a fingerprint, even weeks after the contamination. This is the case with the number of granulocytes – defense cells present in the blood – which in people with Covid-19 is significantly lower than normal.
“Our findings contribute to a better understanding of the disease and can help in the development of potential vaccines, as we now have access to promising biomarkers and can perform even better monitoring,” emphasize the scientists.
