Fever symptoms

Fever symptoms have an essential role in determining whether or not a person has a fever. When we say fever symptoms, these are all subjective feelings of a person. It cannot be manifested and be perceived by our senses. We can gather symptoms by asking a question to a person who has a fever or a febrile person. The person will answer what are his feelings before he or she becomes febrile or his feelings during the course of fever. Symptoms of fever are always reported by a febrile and cannot be seen by the normal eye sight.

Before determining what the usual viral fever symptoms are, identify the different types of fever. There are four common types of fevers. These are relapsing, constant, intermittent, and remittent. The relapsing fever, the person may have fever for a short period of time followed by afebrile periods. It is like an on and off fever. In constant fever, the body’s core temperature varies minimally but always remains greater than normal. During an intermittent fever, there are changes in temperature. For example, a febrile person may have a fever that is 38 degrees and it can go down to normal body temperature or below normal. After that, there will be a fever again and will eventually go down. The difference between relapsing and intermittent fever is that the intermittent fever can go below normal levels. In remittent fever, a broad range of temperature instability occurs over the 24-hour period, all which is above normal. The clinical signs of fever vary with the onset, course, and abatement stages of the fever symptoms. The clinical signs and symptoms of fever of the chilling stage are increased heart rate, increased respiratory rate and depth, trembling, pale and clammy skin, reports of feeling cold, cyanotic nail beds, goose bumps on the skin, and stopping of sweating. On the course of fever the absence of chills, warm skin, photosensitivity, increased pulse and respiratory rates, increased thirst, mild to severe dehydration, lethargic, restless, delirium, or seizure, herpetic lacerations of the mouth, loss of appetite for prolonged fever, malaise, weakness, muscle aches are some of the signs and fever symptoms. In the decline and fever abatement, the signs and fever symptoms are skin that appears blushing and feels warm, sweating, decreased shaking, and possible dehydration. These signs and fever symptoms occur as a product of changes in the temperature control mechanism regulated by the hypothalamus.

Signs and fever symptoms may vary from person to person. Under normal conditions, whenever the core temperature increases above 37 degrees Celsius, the rate of heat loss is increased, resulting in a decrease in temperature toward the set-point level. On the contrary, when the core temperature falls below 37 degrees Celsius, the speed of heat production is increased, resulting in a rise in temperature toward the temperature that the hypothalamus has set. In a fever, however, the temperature set by the hypothalamus changes abruptly, due to the factors affecting the body’s temperature. While the set point changes rapidly, the core body temperature reaches this new set point only after few hours. In this interval, the usual heat production responses that cause elevation of the body temperature. Fever symptoms like chills, feeling of coldness, cold skin due to vasoconstriction, and shivering occur. The person feels neither cold nor hot and no longer experiences chilling when the core temperature gets to have the new temperature set by the hypothalamus. Depending on the amount of temperature elevation, other signs and fever symptoms may occur during the course of the fever. Very high temperatures, such as 41 to 42 degrees Celsius, damage the parenchyma of cells all over the body, chiefly in the brain where damage of neuronal cells is irreversible. Symptoms of a fever can be relieved by simply lowering the temperature of the body.
