How to distinguish bacterial infection from viral infection

Some things we think are the same, but if we look closely we will find some differences between them. It is actually difficult and not that easy to clearly distinguish things that have some similarities. But it is not impossible to distinguish them. Everything has its own characteristics that are different from other things. For example, how to distinguish between bacterial infection and viral infection is a relatively complicated issue, which is not so easy for ordinary people. So let us learn together how to distinguish between bacterial infection and viral infection.

Bacterial infection is an acute systemic infection caused by pathogenic bacteria or conditionally pathogenic bacteria invading the blood circulation, growing and multiplying, and producing toxins and other metabolites. It is clinically characterized by chills, high fever, rash, joint pain, and hepatosplenomegaly. Some may have infectious shock and migratory lesions. An acute systemic infection caused by pathogenic microorganisms invading the blood from wounds or infected lesions in the body. Clinically, some patients may also experience irritability, cold limbs and cyanosis, rapid pulse, rapid breathing, and decreased blood pressure. Especially the elderly, children, those with chronic diseases or weakened immune function, those who are not treated in time and those with complications may develop sepsis or septicemia.

Viral infection is an infectious disease caused by viruses that can parasitize and reproduce in the human body and cause disease. The main symptoms include systemic poisoning symptoms such as fever, headache, and general discomfort, as well as local symptoms caused by inflammatory damage to the virus host and invaded tissues and organs.

If accuracy is required, it must first be determined by the radiology and laboratory departments. If conditions are limited:

1. If there is nothing, you should first determine whether it is a seasonal or epidemic disease. For example, in the case of spring flu, viral factors are more likely to be the cause, while when the seasons change, bacterial factors are more likely to be the cause. You can only make a rough judgment.

2. It depends on the specific situation of the patient. Bacterial infections are mostly caused by environmental contact, while viruses are mostly related to contact with people and animals.

3. Observation of the patient: If the patient generally has fever and swollen lymph nodes, the probability of bacterial infection is higher. If the patient has clear runny nose and body aches, viral infection is more likely.

1. In terms of morbidity, 85-90% are caused by viruses, and bacteria account for less than 10%. In addition, mycoplasma can also cause it.

2. Bacteria: Signs of poisoning are severe, and the patient remains in a bad mood after the fever subsides. Viruses: Signs of poisoning are mild, and the patient is back to normal after the fever subsides.

3. Bacteria: mostly remittent fever (body temperature fluctuates); viruses: mostly prolonged fever (body temperature remains high).

4. There are pus spots on the tonsils------bacteria; there are herpes and follicles on the tonsils------viruses.

5. Tonsils are congested, with an uneven and dark surface - bacteria; tonsils are congested, with a smooth and bright surface - viruses.

Now that I understand what bacterial infection and viral infection are, I think it is not so difficult to distinguish between the two. This can be achieved through careful observation and analysis. In fact, it is not that difficult. As long as you carefully understand the characteristics and differences between the two, it should be easier to distinguish them. It is the same for anything. If you do it seriously, you will succeed. Of course, the same principle applies to how to distinguish between bacterial infection and viral infection.
