More than half of the 236 million of people who have been diagnosed with Covid-19 worldwide since December 2019 will experience long-term symptoms, up to six months after recovering.
This is assured by a study of the
Penn State School (USA) published in ”
JAMA Network Open» The authors of which caution that governments and public health systems must prepare for the large number of Covid-19 survivors who will need care for a wide variety of psychological and physical symptoms.
The authors have carried out a large systematic review of 57 reports that included data from 250,351 adults and unvaccinated children who were diagnosed with Covid-19 between December 2019 until
March 2021 to better understand the short-term and long-term health effects of the virus and have examined global ones in which unvaccinated patients who recovered from Covid-19 participated.
Based on the results, adults, as well as children, may experience different adverse health problems for six months or more after recovering from the coronavirus.
The researchers found that, among those studied, the 79% had been hospitalized and most of the patients (79%) he lived in high-income countries. The median age of the patients was 54 years and the majority of the individuals (56%) were men.
The researchers then looked at the patients’ health over three intervals of one month (short term), two to five months (medium term), and six or more months (long term).
And according to the data, one in two survivors experienced long-term Covid manifestations experienced a variety of residual health problems associated with Covid-19.
These complications usually affected the general well-being of the patient. Overall, one in two experienced persistent Covid manifestations.
Among the most frequent symptoms the researchers found a deterioration in general well-being, more than half of all patients reported weight loss, fatigue, fever, or pain; of their mobility, one in five; neurological, one in four had difficulty to concentrate; disorders of mint healthl, one in three patients was diagnosed with anxiety disorders; lung problems, six out of ten survivors had abnormal chest imaging and more than a quarter of the patients had shortness of breath; cardiovascular; skin problems, one in five patients experienced hair loss or rashes, and digestive, stomach pain, poor appetite, diarrhea and vomiting.
“The findings confirm what many healthcare providers and Covid-19 super-comers have been saying for some time, namely that adverse effects can persist,” says co-investigator Vernon Chinchilli.
“The burden of ill health for Covid-19 survivors is overwhelming,” adds co-lead investigator Paddy Sentongo, “and one must be especially aware of the mental health disorders».
And he adds that “vaccination is our best ally to avoid infection and reduce the possibility of a prolonged Covid even in the presence of an irruptive infection.”
The mechanisms by which Covid-19 causes persistent symptoms are not fully understood. It is speculated that they may be the result of a immune system overload caused by the virus, persistent infection, reinfection, or increased production of autoantibodies (antibodies directed at your own tissues).
The SARS-CoV-2 virus, the agent that causes Covid-19, can access, enter, and live in the nervous system. As a result, nervous system symptoms such as taste or smell disorders, memory impairment, and decreased attention and concentration commonly occur in survivors.
Researchers advocate a early intervention as the fundamental tool to improve the quality of life of these people.
And they warn that the Covid-persistent may cause increased demand for health care and it could overwhelm health care systems, especially in low- and middle-income countries.
