Whether the bacterial infection is important or not needs to be judged according to the type of bacteria, the location of the lesion and the individual’s physical condition, some bacterial infections are lighter and some are more serious. 1. Bacterial species: Clostridium tetani infection can cause generalized skeletal muscle spasms, which can lead to serious consequences if treatment is not timely. Drug-resistant staphylococcus aureus and other drug-resistant bacteria after infection, it is difficult to find effective antibiotics, so it will cause serious consequences. After Clostridium botulinum infection patients can suffer from hypoxia due to paralysis of respiratory muscles. In addition to the above bacteria, there are many other bacteria that can cause serious consequences. 2. Location of the lesion: When the bacterial infection is confined to the skin, it can be cured by antibiotics or incision and drainage. However, when the bacterial infection spreads to the blood circulation and bacteremia occurs, it can cause infections in many parts of the body, resulting in serious consequences. 3. Individual constitution: Normal people’s immune system has a certain clearing effect on bacterial infection and can fight against bacterial infection. However, patients with leukemia, AIDS, malignant disease, etc. have low immune function, which may cause serious consequences when treatment is not timely. The severity of bacterial infections varies greatly from person to person, so it is important to consult a doctor in a timely manner to determine the causative agent and then carry out targeted treatment to avoid serious consequences.
