Two years after the initial Covid-19 infection, at least half of the patients who were hospitalized still have at least one symptom, according to a new Chinese scientific study. This is study with the longest time horizon to date regarding the effects of “long Covid-19”, also known as “post-Covid-19 syndrome”. Until now the “long Covid-19” had not been studied in depth for more than one year from the initial infection.
The researchers, led by Professor Bin Chao of the China-Japan Friendship Hospital, who published the paper in The Lancet Respiratory Medicine, looked closely at 1,192 people with a mean age of 57 who had been treated with Cov for two years. 19 in the city of Wuhan – the epicenter of the pandemic – in 2020.
It was found that patients’ physical and mental health improved over time, regardless of the severity of their initial disease. But 55% – more than half – reported after two years that they had at least one symptom caused by the original Covid-19 infection. The rate with at least one symptom was 68% – at least two in three – six months after the initial infection.
In general, according to the researchers, patients who took Covid-19 tend to have worse health after two years than the general population, and some seem to need even more time to fully recover. About half after two years had symptoms, mainly fatigue or muscle weakness (31%) and difficulty sleeping (31%). They had a smaller percentage shortness of breath, joint pain, palpitations, dizziness and headaches.
They also felt that their general quality of life was worse than before they were infected with the coronavirus, they had more difficulty exercising, experienced more psychological problems (such as anxiety and depression by about 12%), and made more frequent visits to various doctors.
