According to the WHO, the long-term symptoms of COVID is the sequelae of COVID. The official clinical definition of Long COVID or post-acute sequelae SARS-CoV-2 infection ("PASC") was first announced on October 6, 2021. The symptom usually occurs in people who have been diagnosed with or may be infected with coronavirus, and usually "appears within 3 months of infection, persists for at least 2 months, and cannot be explained by other diagnoses."
Common PASC symptoms include fatigue, shortness of breath and cognitive impairment, often affecting daily life. PASC may also cause chest pains, loss of smell and taste, muscle weakness, and heart palpitations, and even have long-term effects on multiple body organs such as the lungs, cardiovascular and nervous systems, and mental health. At present, it is difficult to count the varieties of PASC observed in the world. Severe fatigue is the most common symptom, and even mildly ill people may experience lasting and serious health problems.
It is unfortunate that there is still no effective western medicine that can treat the symptoms of PASC. However, with the increase in reports of PASC symptoms, there is an urgent need to find suitable option to alleviate the emotional, physical problems, and to improve the quality of life.
