It is more difficult to distinguish from the cough alone. It is not that the
cough caused by the viral cold is lighter than the bacterial one. Some viral
infections, such as adenovirus and respiratory syncytial virus infection, make
the cough heavier than the bacterial one.

Is it okay to distinguish it from the sputum? It's not very easy to distinguish, because at the beginning, the sputum may be transparent or white. As the disease progresses, it turns yellow-green. Then, as the condition improves, it turns to transparent or white and it gets better. If there is a difference, the bacterial yellow-green sputum lasts longer.
The reason for this is that yellow-green is the color of neutrophils and enzymes in cells. When a virus is infected, neutrophils will also proliferate and go to the site of inflammation, then yellow-green sputum will be produced. But when the neutrophils arrived, they looked like a virus and couldn't deal with it. Then they won't come. Therefore, they will soon turn into white sputum, but when bacteria come, they will come continuously, resulting in yellow-green sputum time.
If the fever is combined with the viral cold, the fever will start to get better after 2-3 days. For example, the daily maximum temperature is reduced, or the number of fevers per day is reduced, but if it is a bacterial infection, the fever will not be good. So quickly, if antibiotics are not given, the fever may gradually get worse.
In addition, in addition to fever, blood routine has certain reference significance. After a child has a fever for 2-3 days, blood routine can be tested. By looking at white blood cells, neutrophils, and C-reactive protein, you can roughly evaluate it. Haha, this is also Under a rough assessment, it is not 100% accurate.
What if you want to be clear? Nasopharyngeal swabs, throat secretions, and sputum culture tests can be performed. These tests can clarify what the pathogen is, so it is very accurate. But there is a disadvantage that the cultivation is relatively slow, except when the infection is serious, it is generally not checked.
The results of nasopharyngeal swabs are quicker, and they can come out in half an hour, but there are fewer pathogens that can be checked. Therefore, if you feel that your child looks like adenovirus, respiratory syncytial virus, or Mycoplasma pneumoniae, it is worthwhile to check it clearly. You can determine whether to use antibiotics and which antibiotics to use.
