Viral infections can be rapidly diagnosed by blood routine examination. If the blood count is low, it may be a viral infection, while a high blood count is a bacterial infection. A viral antibody test can also be performed in the hospital. If infected with a virus, timely treatment is necessary to avoid greater harm. 1. Most viral infections are characterized by an increase in lymphocytes, while bacterial infections are primarily due to an increase in the number of neutrophils. Generally speaking, the number of neutrophils in bacterial infections can reach over 80%, while viral infections are primarily characterized by an increase in lymphocytes. A more important method of identification is through pathogen detection. Generally speaking, viruses can be detected in viral infections, while bacteria can be detected through bacterial culture. 2. Blood routine tests are generally used to simply determine whether it is a bacterial or viral infection. If the white blood cell count is higher than normal, it is more likely to be a bacterial infection. If the white blood cell count is within the normal range, it is more likely to be a viral infection. Of course, a comprehensive diagnosis should also be made based on clinical symptoms. 3. Most colds are viral infections, accounting for approximately 80% to 90%, while less than 10% are caused by bacterial infections. Among them, infants and young children have a higher chance of bacterial infections than older children, and often develop bacterial infections 3 to 5 days after a viral cold. Viral colds have a certain degree of clustering, such as when there are similar patients in the family; bacterial colds are more sporadic.
