Study: Post-Coronavirus symptoms last 4 months in some patients
A study issued by the National Center for Global Health and Medicine in Tokyo showed that about 20 percent of patients who had Covid-19 reported chronic health problems, including hair loss, two months after the onset of symptoms, and about 10 percent complained of difficulty breathing, loss, or disorder. Sense of smell even after four months.
Shinichiro Morioka, the doctor who led the study at the center, said that he was surprised at the real persistence of symptoms for such a long time, adding that he would conduct more research to study the relationship between the length of symptoms or subsequent effects and between patients' ages and chronic diseases.
This study is believed to be one of the first studies to be conducted on how long the symptoms of Covid-19 last in patients and the subsequent effects.
The doctors primarily conducted telephone interviews with sixty-three patients who were admitted to the center due to their infection with the emerging coronavirus and left between February and June.
Their average age was 48 years, and during their stay at the center, about 30% of them were given oxygen and 8% were placed on ventilators as part of their treatment.
The study says that on the 60th day of the onset of Covid-19 symptoms, twelve patients, or about 19%, were still suffering from an olfactory disorder, while eleven patients, or about 18%, were suffering from shortness of breath.
Ten patients, or about 16%, were still feeling tired, while three patients, or 5%, had taste disturbances.
One hundred and twenty days after the onset of symptoms, seven patients, or 11%, were still suffering from shortness of breath, while six patients, or about 10%, complained of continuing disturbances in the sense of smell.
In addition, fourteen patients, or 20%, nine males and five women, experienced hair loss two months after the onset of symptoms on average.
After a period of time, five of these patients stopped losing their hair, but the other nine were still suffering from this problem when conducting the study.
