width=”600″ >COVID-19Since the outbreak, more and more studies have shown that COVID-19 is not just a respiratory disease, but a disease that affects multiple tissues and organs of the human body. Several studies have pointed out that the new coronavirus infection not only brings disease and death, but also causes other complications, and causes sequelae of varying degrees and symptoms after the patient recovers.
As the virus spreads, new mutants of the virus continue to Emergence, people are more and more concerned about the sequelae of the new crown. Common sequelae include loss of smell, fatigue, dyspnea, cognitive decline, and even depression.
25 July 2022, UKUniversity of Birmingham strong> researchers have published a study in the journal ” Nature Medicine ” A research paper titled “Symptoms and risk factors for long COVID in non-hospitalized adults.”
The study analyzed 2.4 million people and found that COVID-19 patients experienced The long-term sequelae are more widespread than previously thought, including hair loss and loss of libido. Patients reported a substantial increase in the frequency of 62 sequelae symptoms after 12 weeks compared with those without Covid-19.
In the study, researchers analyzed Anonymized electronic health records of people, data collected between January 2020-April 2021, including 486,149 COVID-19 infected people, and 1,944,580 uninfected participants, comparing coronavirus-infected people with uninfected controls groups are compared.
Using only data from patients who were not hospitalized, the researchers were able to determine< strong>Separate long-term symptoms into three distinct categories, including respiratory symptoms, mental health and cognitive problems, and other symptoms strong>. The most common symptoms include loss of smell, shortness of breath, chest pain, and fever.
Also includes amnesia, apraxia (inability to perform familiar movements or commands), fecal incontinence , erectile dysfunction, hallucinations, etc.
Specifically, after 12 weeks, a total of 62 symptoms were associated with There was a significant correlation between new crown infection, and according to the correlation, the main symptoms were ranked as follows: loss of smell, hair loss, sneezing, difficulty ejaculation and loss of libido.

In addition to identifying more long-term symptoms, researchers have uncovered key demographic groups and behaviors that make people Increased risk of long-term sequelae.
Research finds that women, young adults and racial minorities More likely to have long-term symptoms of COVID-19. In addition, persistent symptoms were more frequent among patients with low income, smoking, obesity, and other health conditions.
Risk factors for long-term COVID-19
The data analysis of risk factors is particularly interesting, the researchers said, because it helps us understand what may lead to long-term COVID-19 sequelae, such as smoking and obesity, which put people at increased risk for various diseases and conditions, including COVID-19 sequelae.
However, sex and ethnicity also seem to matter, as women are more likely to develop autoimmune diseases , an increased risk of long-term sequelae was also seen in women in this study.
In conclusion, this study Validated that the long-term sequelae of COVID-19 are very extensive, contributing to further understanding of the complexity and pathology of long-term symptoms, highlighting the degree and diversity of symptom expression between different groups, which cannot be completely determined by lifestyle risk factors or chronic health conditions, etc. Other factors to explain.
The findings may help clinicians and policymakers better measure COVID-19 symptoms and consider how best to manage this symptom burden.
