Long Covid can be so bad that patients have to go to rehab. According to researchers, the number of coronaviruses affects the long-term risk of Covid.

Prolonged symptoms of Covid, such as exhaustion, depressed mood or shortness of breath, can persist for four to twelve weeks after the onset of symptoms after acute coronary disease. The term long covid also includes post-covid symptoms that have not subsided even twelve weeks after the coronavirus Bavarian State Ministry of Health and Welfare.

Those who are vaccinated are protected against Long Covid, according to Long Covid expert Dr. Jördis Frommhold, head physician at the Department of Respiratory Diseases and Allergies at the Median Klinik in Heiligendamm. “There are now many studies that show that vaccination reduces the chance of contracting Long Covid by 70 percent,” says the doctor.

Analysis by American scientists now shows that the number of coronavirus infections must also be taken into account. According to research by Ziyad Al-Aly of the University of Washington School of Medicine and his colleagues at the Veterans Affairs Health System in St. .

Multiple coronary infections increase the risk of complications and death

In their study, the researchers concluded that the risk of heart and lung damage or long-term Covid symptoms increases with each additional Covid-19 infection. “Compared with no re-infection, re-infection contributed to an additional risk of death, hospitalization and complications including pulmonary, cardiovascular, hematological, diabetic, gastrointestinal, renal, mental, musculoskeletal and neurological diseases,” the study authors summarize. For example, you mention cardiovascular disease, diabetes, fatigue and gastrointestinal disease.

For their analysis, Ziyad Al-Aly and his team evaluated health insurance data from US military veterans. Of the nearly 260,000 people with confirmed coronavirus infection, twelve percent have already been infected twice. 0.76 percent were infected with coronavirus three times and 0.08 percent four or more times. For their analysis, the researchers used secondary diseases that occurred within six months of diagnosis. These numbers were compared to a group of 5.4 million uninfected people, such as Central German Broadcasting (MDR) reported.

Multiple infections with the coronavirus double the risk of death

Anyone who gets infected with the corona multiple times doubles their general risk of death compared to people who have been infected only once. According to him, the risk of admission to the hospital increased threefold MDR. The study also shows that damage to the respiratory organs or the cardiovascular system was twice as common in those reinfected.

There are also limitations to this study, such as the fact that most of the data sets examined are of white males. But the researchers are confident: “In order to reduce the overall burden of death and disease caused by Sars-CoV-2, reinfection prevention strategies are necessary,” according to their recommendation.
