One of the symptoms is usually observed in more than 60% of patients who have had COVID-19 after three months, writes "Charter-97".
You can find out if a person has had COVID-19 by three main signs. This is the conclusion reached by experts from the Centers for Disease Control and Prevention of the United States.
They analyzed several scientific papers on this topic and identified several main features.
According to the researchers, the three main symptoms that a patient has suffered from the coronavirus are shortness of breath, joint pain and muscle pain.
Shortness of breath (shortness of breath) is a clear sign of a previous coronavirus infection. Those who are ill may suffer from fibrosis - scarring of the lung tissue, which is a consequence of breathing problems.

A study that looked at data from 55 recovered patients published in the scientific publication Lancet showed that more than 60% of them had this symptom three months after discharge, while just over 70% had abnormalities with computed tomography of the lungs.
Muscle pain (myalgia) also indicates previous COVID-19 combined with other symptoms.
“In general, coronavirus, like other viruses, can cause inflammation of muscle tissue,” said Amir Barzin, a scientist at the Respiratory Diagnostics Center of the UNC Health Center, commenting on one of the consequences of the so-called long-term COVID-19, ”he was quoted by Express.
Dr. Barzin explained that the muscle pain resulting from a viral infection is caused by damage to the muscle fibers by the virus itself.
Joint pain (arthralgia) is the third symptom that often occurs in those who have had coronavirus. Research on this topic is also published in the scientific journal Lancet. It notes that arthralgia is usually detected in 14,9% of patients who have recovered from COVID-19.
