The difference between bacterial and viral infections is that: 1. bacterial infections and viral infections, the pathogenic bacteria are different. 2. blood tests for bacterial infections, suggesting an increase in white blood cells and neutrophils, the higher the elevation indicates that the infection is more serious; and viral infections of the cold, generally appear to be an increase in lymphocytes. 3. symptoms are not the same, bacterial infections of the cold, the general course of the disease is relatively short, the disease is also relatively mild, generally about a week symptoms can improve. 4. The symptoms of bacterial infections are generally shorter and lighter, and the symptoms can improve in about a week; viral colds generally take 10 days or even half a month to improve. 4, treatment is not the same, bacterial infections are generally treated with antibiotics for anti-infection, such as the use of cephalosporins, penicillin antibiotics; and viral infections, colds are treated with antiviral drugs, such as oseltamivir And antiviral oral solution for treatment.
