English text: Fever is not an illness—rather, it's the body's way of fighting infections. When bacteria or viruses enter the body, the immune system raises the internal temperature to create an environment where harmful organisms struggle to survive. Persian translation: Fever is not a disease itself, but the body's way to fight infections. When bacteria or viruses enter the body, the immune system raises the body's internal temperature to create an environment where it is harder for harmful microbes to survive.
Some viruses cause fever without causing respiratory symptoms. These viruses can involve the digestive system or the whole body. Fever usually appears suddenly without any other symptoms. The child may be a little lethargic or lack appetite. In most cases, these types of infections resolve spontaneously with supportive care. The duration of fever is usually several days and its intensity varies. If the fever persists or the general condition of the child worsens, a medical examination is recommended.
Fever accompanied by unconsciousness or abnormal breathing is considered dangerous. In these cases, you should see a doctor immediately.

The child may feel burning or discomfort when urinating. A change in the smell of urine or its cloudiness may also be seen. In infants, symptoms are usually vague and nonspecific. Diagnosing a urinary tract infection requires a urine test. Early treatment is very necessary to prevent kidney damage.
3. Teething and fever
Baby teething can be one of the reasons for a slight increase in body temperature in children, but it usually does not cause a high fever. This increase in temperature is often short-lived and resolves on its own. During this period, the child may become restless, moody and lack of appetite. Increased saliva secretion and wetness around the mouth are common symptoms.
The child's tendency to chew things or bite increases. Sometimes the child's sleep is disturbed and he is restless at night. It should be noted that high or persistent fevers are not usually related to teething. In case of severe or prolonged fever, it is necessary to check other causes by the doctor.
English text: Teething hurts the mouth, and when that happens, children suck and chew on their hands and fingers to self-soothe. Then, germs enter and those germs put a virus into your child's body, which causes the fever. Farsi translation: Teething causes pain in the child's mouth, and in this case, children suck or chew their hands and fingers to calm themselves. This behavior can introduce germs into the child's body, and some of these germs introduce viruses into the child's body, resulting in a fever.
4. Heatstroke and dehydration of the child's body
Long-term exposure of the child to hot environments or direct sunlight increases the risk of heat stroke. Drinking less fluids, especially in hot seasons, plays an important role in the occurrence of this problem. In this case, the child's body temperature rises. The child may become lethargic, dull, or drowsy. Decreased sweating or dry mouth are signs of dehydration. Fever is usually reduced by cooling and rehydration. Prevention is very effective by providing enough water and staying away from extreme heat.
