Pyrexia describes an elevation in the body temperature above the normal range, also known as fever.
Pyrexia is one of the ways our immune system respond in defending the body against infection for a typical child. A normal body temperature is usually considered to be around 97.4 degrees, Fahrenheit 36 degrees Celsius, while the normal body temperature of an adult can be from 97 degrees to 99 degrees Fahrenheit.
Generally, fever occurs when the body temperature rises above 100.4 degrees, Fahrenheit, 38 degrees Celsius. Fevers of 104 degrees, Fahrenheit, 40 degrees Celsius or higher may be extremely dangerous and demand prompt Medical Care as they are viable of causing convulsion, especially in infants, children and old people. Fever can be categorized based on its duration, severity and the pattern duration.
A fever can be acute if it persists less than seven days. An example of an acute fever is malaria Subacute. If it persists up to two weeks, such as seen in typhoid fever, chronic or persistent.
If it persists for more than two weeks, such as tuberculosis or HIV severity or height of fever, fever can be:
Mild or low grade from 100 degrees to 102.2 degrees, Fahrenheit or 38.1 to 39 degrees Celsius. Moderate from 102.3 degrees to 104 degrees, Fahrenheit or 39.1 to 40 degrees, celsius, 4. degrees to 106 degrees, Fahrenheit or 40.1 degrees to 41.1 degrees Celsius, hyperpyrexia greater than 106 degrees, Fahrenheit or 41.1 degrees Celsius pattern. Remittin fever fever may come and go with fluctuation in temperature. At a regular interval such as in infective endocarditis, continuous fever fever fluctuate in a small variation of about one Celsius.
In 24, hours, such as in a urinary tract infection intermittent fever, fever comes down to normal each day, such as in malaria, intermittent fever is referred to as tertian fever when it persists for 48 hours and quotidian fever, if it persists for 24 hours, relapsing fever fever That reappears after a certain period of time, pale Epstein fever fever that is dominant in people with Hodgkin’s lymphoma. Such a patient suffers from high fever for one week and low fever for the next week.
However, debate exists as to whether this type of pattern truly exists.
Fever can be caused by bacterial viral parasitic infection such as common cold, malaria, meningitis, a malignant tumor certain medications such as antibiotics and drugs used in high blood pressure or seizure treatment, inflammatory conditions such as rheumatoid arthritis lupus or inflammatory bowel infection, alcohol withdrawal, dehydration overexposure To sunlight blood clots, food poisoning, a side effect of vaccinations such as those used for tetanus use of illicit drugs such as cocaine cancer, mostly kidney cancer, Leukemia and Lymphoma metabolic disorder.
Sickness Behavior associated with fever may include shivering, lack of appetite, a headache, sweating, irritability, dehydration, sleepiness lethargy, inability to concentrate muscle and joint ache.
Diagnosis and treatment
Diagnosing fever is easy. The patient temperature is taken with a thermometer. A high reading is indicative of fever Diagnostics. Tests such as blood tests, urine tests, X-ray and other Imaging tests may be ordered depending on symptoms and medical history. If young infants, especially those under 28 days, fever, can indicate a serious illness and the baby may need to be admitted into the hospital for testing and treatment.
Treatment may depend on the cause of your fever. If a bacterial infection is causing your fever, the doctor May prescribe antibiotics. Antibiotics have no effect against the virus. Therefore, antiviral drugs may be used to treat certain viral infections. Over-The-Counter fever-reducing medications such as acetaminophen, Tylenol or Ibuprofen Motrin, may be recommended by the doctor. Fluid intake to avoid dehydration, which can worsen the condition.
