A study conducted by Swiss scientists shows that the majority of medical workers infected with the original strain of the coronavirus still suffer from certain health problems four years later. According to the research, so-called “Long COVID” is transitioning into a chronic condition that requires systemic support.
Study Results
The study, which took place between 2022 and 2024, included 456 infected medical staff and 571 non-infected individuals. Results showed that even at an average of four years post-infection, 60% of those surveyed still complain of at least one symptom. The most common complaints reported were:
-
Chronic fatigue (22.8%);
-
Loss of smell and taste (11.4%);
-
“Brain Fog” (8.3%).
Notably, while the intensity of other symptoms decreased over time, “brain fog” and cognitive impairment remained almost unchanged.
Scientists emphasize that the decline of symptoms is not linear. Although most patients experience mild complaints, a portion of them continue to have moderate to severe functional impairments. The study’s authors urge healthcare systems to recognize Long COVID as a chronic disease requiring ongoing clinical and social support.
Researchers believe it is essential to develop specific strategies to assist medical personnel. This includes flexible workload schedules and rehabilitation programs to ensure the system does not lose experienced and qualified staff who are struggling with post-viral complications.
