The different shapes of temperature curves formed by routinely measuring the body temperature of a febrile patient and marking it on the temperature chart are known as heat patterns. Heat pattern is one of the manifestations of the interaction between pathogenic factors and the body, and many febrile diseases have a relatively specific heat pattern, so a typical heat pattern is valuable for disease diagnosis. Most of them are associated with primary illnesses that affect the body’s defense function, and there are more cases of hospital-acquired infections. Chills, high fever, profuse sweating, and a bimodal fever pattern are more common, and occasionally a trimodal fever pattern, which is rare in sepsis caused by other pathogens, is worthy of attention. How to prevent the triple fever type? 1, winter should pay attention to the cold and warmth: in the hot and cold climate changes at any time to increase or decrease clothing, avoid cold and rain and excessive fatigue. 2, strengthen physical exercise: enhance their resistance and adaptability to the natural environment. 3, drink plain water: autumn and winter dry climate, the human body is prone to water shortages, often drink plain water, not only to ensure that the human body needs, but also can play a diuretic detoxification, the elimination of body waste effect. 4, pay attention to labor protection: to prevent trauma, such as trauma should be timely disinfection bandage, the original local inflammation of timely antibacterial treatment, squeezing is strictly prohibited. 5, to prevent the spread of bacteria: various diagnostic and technical operations in the hospital should be carefully implemented with strict disinfection and aseptic techniques, strengthen the disinfection and isolation system in the hospital, prevent cross-infection, and reasonably apply antibacterial drugs and adrenocorticotropic hormones to avoid causing dysbiosis and reducing the immunity of patients. 6, active immunity: there are two vaccines for prevention, containing 23 serotypes (more common types of infection) of the podoconjugate vaccine, in adults, especially among young people, immune effect is good, but can only last 5 years, must be reinforced injection, the elderly maintain a shorter time, every 3 to 4 years should be reinforced injection once, this vaccine for small infants immune effect is very poor, so the podoconjugate and tetanus or diphtheria toxoid This vaccine is ineffective in immunizing small infants, so the conjugate vaccine, which is made by covalent combination of proteins such as podoconjugate and tetanus or diphtheria toxoid, can produce antibodies in small infants under 18 months of age for three consecutive vaccinations, which not only protects infants but also reduces the incidence of adults and effectively reduces the infection of drug-resistant strains. 7.Passive immunization: For HIV-infected patients, patients with malignant tumors, and those who do not produce antibodies from vaccination, immunoglobulin can be injected regularly. 8.Drug prevention: When there is a risk of infection, oral penicillin drugs can be used for prevention.
