“Long Covid” symptoms: women suffer significantly more often from long-term effects of Covid-19


 The  study on the Corona long-term consequences came to the result that three out of four patients (76 percent) are still taking six months later at least one Symptom suffered. Were there Women after a Covid-19 disease more often of the Long-term consequences affected as Men. Persons whose infection with the Coronavirus Sars-CoV-2 led to a disease course of severity 5-6, also suffered stronger under Long-term consequences.

But what symptoms did the patients suffer from months after they did? Corona infection? Of those surveyed, 63 percent said they were under Muscle weakness and fatigue to suffer. Sleep disorder were an existing problem for 26 percent. Symptoms like Hair delight (22 percent), a impaired sense of smell (11 percent) Joint pain (9 percent) and a impaired sense of taste (7 percent) occurred. In the 6-minute walking test, the values ​​of 23 percent of the participants were conspicuous. At the strongest those who had disease severity of five or six were also affected.

Study on corona long-term consequences: results support previous studies

Yet the results of the Corona-Studie by Chaolin Huang and his colleagues must also be viewed with certain reservations. So has the study for example not the entire health status of the respondents before their infection with the Coronavirus Sars-CoV-2 recorded, criticizes the “Ärzteblatt”. It is therefore unclear whether certain Pre-existing illness, also of a psychological nature, also had an influence.

Italian researchers who study out Wuhan commented, stated in “©

 The  Lancet” that only four percent of the test subjects could be cared for in the intensive care unit. Nevertheless, the results of the Corona-Studie of Chaolin Huang and his colleagues with those of previous studies, summed up the scientists from Italy.

Because Corona long-term consequences like fatigue, shortness of breath and the persistent loss of the Sense of smell and taste were, for example, the most common in a corona study from Switzerland Symptom determined after an illness. And a study by Oxford University showed that one in five Covid-19-Sick after diagnosis suffers from mental health problems.

“Long Covid” study: the overall extent of the impact of Corona on humans is still unclear

“Because it is with Covid-19 When it comes to such a new disease, we are only just beginning to understand the long-term effects it has on patient health. However, our analyzes indicate that most patients have to live with at least one aftereffect of the virus when they leave the hospital, ”explains Professor Bin Cao, who worked on the study, to“ EurekAlert! ”. It is especially important to work with the former Coronavirus To accompany infected people medically.

To the Corona long-term consequences or „Long COVID“ to be understood more precisely further studies absolutely necessary, according to the researcher. Only then can you see the full extent of the Effects of Corona on People to capture. (Sophia Lother)
