How many days it takes to recover from a recurrent viral cold fever depends on the type of viral infection and the severity of the illness. Viral colds are relatively common respiratory illnesses that commonly manifest as fever, headache, nasal congestion, and runny nose. If the cold is caused by a common viral infection, or a viral cold with mild clinical symptoms, the patient usually has a fever that lasts about 3-5 days. If it is caused by influenza virus or combined with bacterial infection or viral myocarditis, the duration of fever may be prolonged, usually taking about 10-14 days or even longer. When viral flu patients have symptoms such as chest tightness, shortness of breath, palpitations, anterior heart area discomfort and weakness of the limbs, they need to visit the hospital’s general internal medicine department or cardiology department in a timely manner and undergo relevant tests such as cardiac enzymes to clarify whether they are combined with viral myocarditis to avoid delaying the condition.
