Bacterial colds, presenting with clinical symptoms such as fever, headache, sore throat, nasal congestion, and sometimes yellow nasal discharge, along with coughing. For patients with simple bacterial colds experiencing these symptoms, these clinical manifestations alone cannot distinguish between a Wind-Heat cold and a Wind-Cold cold. It is known that the differentiation between Wind-Heat and Wind-Cold colds is based on the perspective of Traditional Chinese Medicine and cannot be determined from the perspective of bacterial infection. Therefore, clinically, it is often not possible to differentiate bacterial colds based on these symptoms alone.
