What is a Fever?
A fever is a body temperature above the normal of 98.6 degrees F. (37 degrees C.). It is usually measured with a thermometer. Once the new temperature is reached, there is a feeling of warmth. A fever can be caused by many different conditions ranging from benign to potentially serious.
Types of Fever :
There are some types of fevers are here
1. Viral fever:
It refers to a broad spectrum of conditions where viral infections are associated with elevations of body temperature. e.g., Bacteria Virus.
2.Continuous fever:
Temperature remains above normal throughout the day and does not fluctuate in 24 hours, e.g. typhoid, urinary tract infection, brucellosis, or typhus.
3 . Intermittent fever:
The temperature elevation is present only for a certain period, later cycling back to normal,
e.g. malaria, kala-azar, pyaemia, or septicemia.
4. Remittent fever:
Temperature remains above normal throughout the day and fluctuates more than 1 °C in 24 hours, e.g., infective endocarditis.
5. Dengue Fever:
Dengue is transmitted by the number of mosquitoes within the genus Aedes, principally Aaegypti. e.g., Mosquitoes.
6. Brain Fever:
Brain fever is the fever due to infection and inflammation of the brain also called as encephalitis. e.g.,Viral infection.
Signs and symptoms:
* In the mild form of the disease, flu like symptoms is seen. Headaches, body aches and a skin rash characteristic most of these viral fevers. They may affect any age group, and are seen world-wide. They require only symptomatic treatment. Some are highly contagious.
* Most of them are not dangerous and self-limited, but some can progress rapidly leading to death. In severe cases vomiting, drowsiness, severe headache, confusion, sensitivity to light, occasionally stiffness of neck and back, clumsiness, unsteady gait, irritation, reduced control over temper, sudden fever and seizures may be seen.* Brain fever describes a medical condition where a part of the brain becomes inflamed and causes symptoms that present as fever. The terminology is dated, and is encountered most often in Victorian literature. Conditions that may be described as brain fever include:
Usefulness:
Fever in children is believed to train the immune system and prevent asthma.In theory, fever can aid in host defense. There are certainly some important immunological reactions that are spaced up by temperature, and some pathogens with strict temperature preferences could be hindered. Fevers may be useful to some extent since they allow the body to reach high temperatures, causing an unbearable environment for some pathogens .White blood cells also rapidly proliferate due to the suitable environment and can also help fight off the harmful pathogens and microbes that invaded the body.
Treatments:
Each of the major causes for fever associated with cancer has recommended conventional treatment procedures. For infection-related fever, broad-spectrum anti-biotics, given orally, rectally, or intravenously, are the principle method of control. Some antibiotics may be started before a definitive diagnosis is made to retard additional complications caused by the infection. Treatment typically is administered for five to seven days as long as the fever and infection show a positive response.
