Viral colds, which are self-limiting, usually have a course of treatment of about 5-7 days. If you have a fever, you can take oral antipyretics such as ibuprofen or Nebulizer. Alternatively, for causal treatment, you can take oral antipyretic drugs and drink more water to improve your immune system. Most of the viral colds heal well, but there are also deaths caused by colds, which have underlying diseases or other systemic complications, such as damage to the heart muscle, or excessive application of antipyretic drugs, some liver and kidney function damage, etc.
