According to a new study of the Chinese Academy of Sciences, the so-called "long-term Covid-19" or post-core syndrome affects every third person who has suffered a coronavirus infection. The study lasted a year and covered more than 70,000 inhabitants of China from 18 to 60 years. Its results show that post-core syndrome is a multifaceted disease that affects almost all organ systems, causing considerable difficulties for people even after recovery from the Covid-19.
Postcopy syndrome is a condition in which a person continues to experience a variety of symptoms associated with the disease, even after the viral infection has already disappeared from his body. Among the most common manifestations of the syndrome: persistent fatigue, headache, shortness of breath, loss or distortion of smell (anosmia and steam), muscle weakness, low body temperature and impaired cognitive functions, such as decreased attention and sleep problems.
The syndrome can affect various organ systems, causing neurocognitive disorders, breathing problems, nervous system disorders, metabolism, circulatory system, and mental health. Because of this, the symptoms of postcous syndrome remain quite diverse, and the exact nature of some symptoms is still unknown.
The study has shown that among more than 30% of respondents who experienced the manifestations of post -core syndrome, the primary symptoms remain:
- Fatigue - 30% of patients,
- Memory deterioration — 28%,
- Reducing the ability to physical activity — 18%,
- "Brainstorm fog" (concentration problems) - 17%.
Researchers have collected information about the symptoms of postcous syndrome during the year through online surveys. The interviewees independently reported the nature and duration of the symptoms, and scientists group this data according to the status of SARS-COV-2 infection.
The study has shown that vaccination significantly reduces the manifestations of post-core syndrome-in particular, the symptoms are reduced by 30% -70% of people who have received several doses of vaccine or revaccination. However, in the case of re-infection of the Covid-19, the risk of developing postcous syndrome increased, and the symptoms became more serious.
