Describe the main causes of fever, which is an important .

The cause of fever is mainly divided into an infectious fever and a non-infectious fever. If a child has a fever, the most common one may be an infectious fever, and if there is an infectious fever, it is more common in it, mainly a fever caused by a viral infection, and other bacterial infections, and fever caused by mycoplasma infection.

Fever is the most common clinical symptom, fever is not specific, many diseases can cause fever, there are also some patients after routine examination and **, the body temperature can not be reduced to normal, can not be clearly diagnosed, called unexplained fever diagnosis can not cause fever, need to consider the following points, first, the fever time lasts more than three, Tuesday, the body temperature has exceeded many times.

Try to describe the main cause of fever You have a cold, there is heat inside, there is inflammation, there is fever, the reason is that there is inflammation.

Many of the most common causes of fever are various infectious diseases, such as tuberculosis, lung abscess, sepsis, bronchitis and other diseases, but also malignant tumors, drug fever, rheumatoid arthritis, systemic lupus erythematosus and other diseases.

Fever is a great omen

c.Independence of the family of Lu Fan disease.

d.Syndrome.

e.Signs. Correct answer: B

1. What is the heating phenomenon of equipment and the main reason for the heating phenomenon, the main causes of heating of electrical equipment include: (1) short circuit When short circuit, the current in the line generally increases several times to dozens of times, and a large amount of heat energy is generated sharply, which can make the insulation of the conductor's body immediately burn through; If the heat energy is transferred to the surrounding combustibles, it can cause combustion. (2) Overload The selection of wires and equipment is unreasonable or the current carrying exceeds the rated value, which will cause the equipment to overload and heat.

3) Poor contact Poor connection of wire joints, poor contact of movable contacts, and electrolytic corrosion of copper and aluminum joints will lead to overheating. (4) Poor heat dissipation All kinds of electrical equipment generally have certain heat dissipation or ventilation measures, if these measures are damaged, it may cause the equipment to overheat. (Qingdou 5) Electric lamps and electric bridge stoves that work directly with the heat generated by the electric current may also overheat if they are installed or used improperly.

Infection with various pathogenic microorganisms.
