Milo Puhan, director of the EBPI, explains: “If the course is severe, the risk of suffering from long-term symptoms is higher – but they also exist after a mild course.”

Around a quarter of those who tested positive for corona suffer from long-term consequences. In addition to physical complaints such as severe tiredness, shortness of breath and cough, those affected also struggle with psychological problems. Symptoms of depression or anxiety disorders are increasing.

This is the result of research by the Institute for Epidemiology, Biostatistics and Prevention (EBPI) at the University of Zurich. Milo Puhan, director of the EBPI, explains: “If the course is severe, the risk of suffering from long-term symptoms is higher – but they also exist after a mild course.”

Long-term physical and psychological consequences
The Zurich research team examined the long-term effects of 1,500 corona-positive people with various disease courses: from no symptoms to very serious illnesses.
–
The subjects were selected randomly from across the Canton of Zurich. They were divided into two test groups. The first, consisting of 450 subjects, was infected in spring 2020, while the remaining 1,050 people had only tested positive since August 2020.

More antibodies after severe illness
In addition, blood was taken from the test subjects to test for antibodies. In the first group, antibodies were detected in 96 percent of those tested six months after the disease. The illnesses of the spring group were mostly severe, because in the spring was still restricted and often only tested in the case of severe symptoms. Together with the results of the second group, the following tendency emerged: After a more severe illness, the body is more likely to produce (more) antibodies in the blood.
–
But: of 1050 people, 15 percent have no antibodies at all – mostly those with weak symptoms. Nevertheless, they can also be immune because, in addition to antibodies, defense cells are also relevant for later protection. This, as well as the immunity of the vaccinated, is being researched in more depth.

Home and nursing staff more affected
One of the studies is also dedicated to home and home staff. While employees of Spitex organizations hardly fell ill more often than the rest of the population, nursing and home staff are significantly more affected. On average, around 14.9 percent of them were infected – but the number strongly depends on the home. (ouch)
