The distinction between viral influenza and wind-heat cold is mainly the different naming conventions used by two different medical systems for the common cold. Viral influenza is a term used in modern medicine to describe a viral infection. In contrast, wind-heat cold is a term used in traditional Chinese medicine (TCM) for a type of cold that occurs after being affected by a pathogenic heat.

These two terms are completely different. The pathogen of viral influenza is primarily caused by a viral infection. On the other hand, wind-heat cold is diagnosed based on symptoms, suggesting that the individual might have been affected by pathogenic heat, or has internal heat, leading to the condition.

Therefore, generally, viral influenza is not treated with traditional Chinese medicine. Wind-heat cold, conversely, is not treated with Western medicine. So, if diagnosed with viral influenza, one would typically take some antiviral medications along with Western cold medicines. If diagnosed with wind-heat cold by a TCM practitioner, some appropriate heat-clearing and detoxifying Chinese medicines would be prescribed. These represent two distinct medical systems with their unique diagnostic labels for the illness.
