Among the major health problems related to post-Covid illness, a series of conditions affect almost all organs and systems of the human body. Among the patients who survived the Sars-Cov-2 coronavirus infection, some can last for several months.
As the Covid-19 pandemic progresses, it is clear that some recovered patients are struggling to recover from the infection. Certain symptoms can last for months in a debilitating manner, not only in patients experiencing severe Covid-19, but also in patients experiencing mild or moderate infections.To clarify these consequences, it is also called “Long-term Covid” or the long-term sequelae of Covid-19, Is a new study published in the journal natural A team of researchers from Washington University School of Medicine in St. Louis gave an overview of post-Covid syndrome. Scholars have also shown that in the six months after Covid-19 is diagnosed, the risk of death increases for survivors (including those who have not requested hospitalization).
The long-term effects of Covid-19
The study is the largest analysis of infection results to date, involving approximately 87,000 Covid-19 patients in the United States, of which 73,000 were not hospitalized, and nearly 5 million people served as a control group.Comparing clinical data extracted from the federal database of the Veterans Health Administration, it can be calculated that patients who recover from the initial infection (after the first 30 days of the disease) have a higher risk of death from the disease. Almost 60% increase In the six months after remission, it is determined by a series of complications that may have a huge impact on survivors in the next few years.
The researchers pointed out that at the end of six months, the excess deaths of all Covid-19 survivors are estimated to be 8 deaths per 1,000 patients, which is three times the proportion of patients requiring hospitalization, and 29 excess deaths per 1,000 patients6 A few months after recovery. “These subsequent deaths are due to long-term complications of the infection and are not necessarily recorded as deaths from Covid-19 -Senior author of the study, Ziyad Al-Aly, professor of medicine at Washington University School of Medicine in St. Louis, director of the Center for Clinical Epidemiology, and head of the Department of Veterans Affairs Research and Education Services, St. Louis Health Care System. As for the total number of deaths caused by the pandemic, these figures indicate the number of deaths from the virus that we are calculating They are just the tip of the iceberg“.
Consequences for almost all organs
To understand the long-term effects of the disease, researchers separately analyzed the medical records of more than 13,000 patients who were hospitalized for Covid-19 and compared them with many patients who were hospitalized for seasonal flu.The comparison results show that there are still major newly diagnosed health problems among Covid-19 patients Six months after infection. The conditions outlined in the figure above have been observed in almost all organs and systems of the human body:
- Respiratory system: Continuous cough, shortness of breath and low blood oxygen level.
- nervous system: Stroke, headache, memory impairment and lack or decreased sense of taste and smell.
- Mental Health: Anxiety, depression, sleep disorders and drug abuse.
- metabolism: New onset of diabetes, obesity and high cholesterol.
- Cardiovascular System: Acute coronary artery disease, heart failure, heart and irregular heart rhythm.
- Gastrointestinal system: Constipation, diarrhea and acid reflux.
- Rene: Acute kidney injury and chronic kidney disease that may require dialysis in severe cases.
- Coagulation regulation: There are blood clots in the legs and lungs.
- skin: Skin rash and hair loss.
- Musculoskeletal system: Joint pain and muscle weakness.
- General health: Discomfort, fatigue and anemia.
Obviously, all these problems have not been cured, but many people have experienced many different diseases that have a major impact on their health and quality of life. “Compared with seasonal flu -Professor Al-Aly added- Consequences of Sars-Cov-2 coronavirus infection Both the degree of risk and the degree of involvement of organs and systems show a significantly higher disease burden. Some of these problems may improve over time, such as shortness of breath and coughing, but other problems may get worse.Therefore, we will continue to follow these patients to understand the impact of the virus infection in the first six months after the diagnosis of Covid-19“.
