What is considered a fever:
A fever is a body temperature that is higher than normal. A normal temperature can vary from person to person. But it is usually around 98.6 F (37 C). In practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 C). Now today we will describe its symptoms and Fever treatment.
What is fever:
- Body temperature rises because of an infection, it’s called a fever. Fevers are caused by chemicals called pyrogens flowing in the bloodstream.
- Fever may occur with almost any type of infection or illness. A fever is not a disease. It is usually a sign that your body is trying to fight an illness or infection.
- Your body is trying to kill the virus or bacteria that caused the infection. Most of those bacteria and viruses do well when your body is at your normal temperature.
Other names: Pyrexia and Bukhar / Jwar
Effect according to grades of fever:
- Low grade, from 100.5–102.1°F or 38.1–39°C – cause weakness.
- Moderate, from 102.2–104.0°F or 39.1–40°C – cause weakness.
- High, from 104.1–106.0°F to or 40.1-41.1°C – cause weakness or exhaustion but are not in themselves a serious threat to health.
- Hyperpyrexia, above 106.0°F or 41.1°C – More serious fevers, in which body temperatures rise to 108 °F (42.22 °C) or more, can result in convulsions and death. ever with infections don’t cause brain damage. Only temperatures above 108° F (42° C) can cause brain damage.
In all condition fever treatment is essential.
- For fever treatment, if the fever is very high, your health care provider may recommend taking an over-the-counter medicine such as acetaminophen or ibuprofen.
- Adults can also take aspirin, but children with fevers should not take aspirin. It is also important to drink enough liquids, to prevent dehydration.
- If your temperature runs 100.4°F (38°C) or higher, you have a fever. Stay in bed and rest.
- Keep hydrated. Drinking water, iced tea, or very diluted juice to replenish fluids lost through sweating.
- Wash your hands, legs, and head with cold water till fever not reduce to below 100’C.
Types of Fever:
A very high temperature which doesn’t improve with antipyretics can indicate a septic fever and the patient should be seen quickly and reviewed to prevent any further deterioration in their state of health.
The temperature remains above normal throughout the day and fluctuates more than 2° Celsius in 24 hours. Mostly seen in patients with typhoid fever and infective endocarditis.
Where the temperature remains above normal throughout a 24-hour period and does not fluctuate more than 1° Celsius in 24 hours. This type of fever occurs in lobar pneumonia, typhoid, urinary tract infection, infective endocarditis, brucellosis, and typhus.
In a 24 hour period, the temperature is only present for some hours of the day and the rest of the time is normal. The spike can occur the same time each day, every other day or every few days but is normally in a repetitive pattern. Examples of some diseases. which have an intermittent fever are malaria, pyemia, and septicemia?
Pel Ebstein fever:
There is a regular alternation of recurrent bouts of fever and febrile periods. The temperature may take 3 days to rise, remain high for 3 days and then remits over 3 days. The patient could then be apyrexial for 9 days.
Cyclical recurrent fevers or periodic fevers:
These are recurrences of fever which last from a few days to a few weeks and are separated by symptom-free intervals. This type of fever caused by recurrent infection. Malignancy or non-infectious inflammatory diseases. Attacks of fever which follow the same course normally have a non-infectious cause.
Fever Symptoms appear due to:
- Malaria Smear of MP
- Dengue Platelets, IgM/IgG serological test
- Typhoid Widal serology
- Chikungunya ELISA or CHIKV-IgM
- Leptospirosis Microscopic Agglutination Test (MAT)
- Hepatitis (HAV), (HBV) and (HCV), a physical exam and blood tests
Diagnosis of fever by a blood test:
Hemoglobin test used for anemias and blood-related disorders. This may be the cause of the fever.
Mean corpuscular volume (MCV) test measures the average volume of red blood cells. The abnormal levels may indicate certain problems which may cause fever.
This test is used to detect any infections causing fever.
It is an erythrocyte sedimentation rate. ESR test used for inflammations, infections, cancers, and autoimmune disorders. These conditions will lead to fever.
The smear of MP:
Malarial parasite smear test used to detect malarial infection. So it can be a malarial fever.
WBC count test helps to detect any infections in the body. The fever can be sometimes due to severe infections.
Red blood cell count test is done to detect any blood-related disorders which may be the reason for the fever.
It is a liver test to assess the functioning of the liver. Fever appears in case of liver injury, liver disorders and cases of liver failure.
Hematocrit (HCT) test measures the proportion of red blood cells in the body. Abnormal levels of it may indicate a certain disease and it may cause fever.
