Through the current symptomatology study of patients with novel coronavirus, it has been found that patients infected with novel coronavirus can have muscle aches and pains and weakness. However, on the other hand, it is not necessarily true that muscle aches are caused by the novel coronavirus. There are many other similar diseases that can cause muscle aches and pains, such as influenza or the common cold in infectious diseases, which can be accompanied by muscle aches and pains. In addition, non-infectious diseases, such as muscle pain after excessive exercise, or muscle strain due to muscle pulling, can also cause muscle pain. Therefore, the diagnosis of novel coronavirus infection is usually based on a combination of blood tests, chest X-ray or lung CT, and viral nucleic acid, rather than on a single symptom.
