Cold itself is a respiratory disease caused by viral infection, there is no such thing as a bacterial cold. Colds can be combined with or secondary to bacterial infections, and usually get better in about 5-7 days, but if the condition is serious, it will take longer, and there is no such thing as a bacterial cold or a viral cold, which is easier to get well. Colds are common and frequent, and can be categorized into two different types: common colds and influenza. Common colds are self-limiting, and for most people, respiratory symptoms caused by colds will disappear within 5 to 7 days. Influenza viruses cause influenza, which requires timely use of oseltamivir antiviral treatment, can usually be improved in 5 to 7 days. If the course of the illness is prolonged or prolonged, it is necessary to consider whether there is a combined or secondary bacterial infection. If there is evidence of bacterial infection, anti-infective treatment, commonly used such as amoxicillin, cefixime, etc., can also usually be improved in about 5 to 7 days. However, the more severe the cold, the longer the recovery time. If you are not feeling well, we recommend that you consult a doctor, complete the relevant laboratory tests to comprehensively assess your condition, and follow the doctor’s instructions for reasonable and standardized treatment.
