The normal temperature of our body is 98.6 degrees F (37 degrees C). When the body temperature starts to grow more than the normal state, then the condition is called fever or pyrexia.
Fever is a way of fighting the body’s disease. Therefore fever is a symptom of infection. During the transition, our blood and the lymphatic system produce white blood cells (WBC-WBC), which fight infection (microbes). In this situation, the temperature of our body increases, due to which there is pressure on our muscles and it starts shivering.
Usually, our body temperature does not go up from 41 to 42 degree Celsius (105.8 to 107.6 degrees Fahrenheit). We all have to face cold waves and tiredness in the body due to pyrexia. The pyrexia can also be due to many other conditions, which is normal, can reach even a serious condition.
This includes viral, bacterial and parasitic infections, such as ordinary cold, urinary tract infection, brain fever (meningitis), malaria, appendicitis etc. Its non-infectious causes include vasculitis, deep vein thrombosis, side effects of medicine and cancer, etc.
It is different from hyperthermia. Hyperthermia increases body temperature, which is more than a set point temperature. This happens either due to the occurrence of heat or not leaving a sufficient amount of heat.

Types of fever
How many fevers are there?
- Continuous Fever
If the body temperature is more than normal for more than 24 hours and this temperature has not changed more than 1 degree Celsius. This type of pyrexia occurs in lobar pneumonia, typhoid, urinary tract infection, infectious endocarditis, brucellosis, and typhus.
- Remitted Fever
In this, the temperature of the body remains above normal for the whole day and in this period the temperature does not change more than 2 degrees Celsius. This type of fever is seen in patients with typhoid and infectious endocarditis.
- Intermittent Fever
In this fever, the high temperature lasts only for a few hours in a 24-hour period and the rest is normal for the rest of the day. This procedure usually repeats itself every second day or in a few days. Some diseases responsible for intermittent pyrexia include malaria, pyemia, and septicemia.
- Septic fever (Hectic or Septic)
A high temperature, in which there is no improvement in antiparasitics, indicates septic fever. In this stage, the patient should be looked after and should be reviewed to prevent any fall in his health.
- Pel Ebstein Type
There is a change in body temperature repeatedly. It can take 3 days to increase the temperature, the temperature can stay high for 3 days and then decreases in 3 days. After that, the pyrexia is removed for 9 days.
- Low/periodic grade fever
It is a recurrence of fever, which lasts for a few weeks for several weeks. There are intervals between pyrexia, in which there is no symptom present. This fever has a pattern, which can be caused by repeated infections, malignancy or non-infective inflammatory diseases.
Non-infectious agents are responsible for the attacks of pyrexia that follow the same order, such as Still’s disease, Rheumatoid arthritis, Crohn’s disease, and Bechet’s syndrome.
How much temperature is called fever
- Low-level fever ranges from about 100 degrees F – 101 degrees F.
- 102 degrees F is the intermediate level for adults, but the same temperature should be taken for medical care if the infant (0-6 months) is the same.
- High-level fever ranges from 103 degrees F-104 degree F.
- If the temperature increases severely, i.e. 104 degrees F -107 degrees F or greater. High fever is called hyperpyrexia.
People’s status may vary in low or middle-level pyrexia. However, fever with temperatures of 104 ° F (40 ° C) or higher can be dangerous, in which urgent home remedies or medical care is necessary. If this is not done then the patient can develop serious complications. This happens especially in infants, children and the elderly.
Symptoms of fever
The common symptoms of fever are:
- The temperature above 100.4 F (38 C) in adults and children
- Shiver, tremble, and chills
- Pain in muscles and joints or pain in other parts of the body (Rheumatoid arthritis)
- Frequent or excessive sweating
- Fasting of heart rate or palpitations
- Skin flushing or hot skin
- Fainting, dizziness or a light headache
- Eyes Pain
- Decrease in hunger
- Sneezing of the nose
- A sore throat, coughing, hoarseness of voice
Due to fever
A fever occurs when an area of your brain, called the hypothalamus (also called “thermostat”, also called your body’s “thermostat”), elevates your body’s fixed temperature to the fixed point. When this happens, you may feel cold and you wear too many clothes or you clamber in a blanket or you may be pausing, which causes excessive heat in the body. As a result, the body temperature becomes high.
The normal temperature of the body varies throughout the day, such as in the morning the body temperature will be low and the temperature increases in late afternoon or evening. However, most people consider the temperature of 98.6 F (37 ° C) as normal. Your body temperature may range from 97 F (36.1 C) to 99 F (37.2 C) above the degree, which is considered normal.
Due to the increase in fever or body temperature –
- Virus Infection (Read more: Infection: Types, Symptoms, Treatment)
- Infection (bacterial infection)
- Heat exhaustion due to heat
- Some inflammatory conditions, such as rheumatoid arthritis
- A malignant tumor
- Some medicines, such as antibiotics and drugs used for the treatment of high blood pressure.
- Some immunizations, such as diphtheria, tetanus and echopathic pertussis – DTAP (acellular pertussis – DTaP) or pneumococcal vaccine
Rescue from fever
You can succeed in preventing fever by reducing the risk of infectious diseases. Here are some suggestions, which can help –
- Wash your hands often and you teach them to kids too. Before eating this, especially after using toilets, after spending time in the crowd, after going to an infected person, after touching animals and in public vehicles during the trip.
- Teach your children to wash hands well. Put soap well on the front and back of the hands and then wash them well with water.
Always keep hands sanitizer with you. When you do not have soap and water available, use it.
- Avoid touching your nose, mouth or eyes, because viruses and bacteria can enter your body due to these paths and cause infection.
- Keep your mouth and nose covered while sneezing or coughing and ask your children to do the same. Whenever possible, stay away from others while sneezing and coughing, so that they do not suffer from this infection.
- Avoid sharing cups, water bottles, and utensils with your children.
Diagnosis of fever
It is very easy to diagnose fever. The thermometer can test the patient’s body temperature and diagnose pyrexia only at home.
Patients are advised to rest because physical activity increases with physical activity. Fever is a common clinical event. In most cases, the cause of the pyrexia is determined soon.
Clinical problems start when a person has pyrexia for a long time and its cause is not easily understood. The cause of pyrexia can be classified as follows:
- Infectious agent
- Immunization or metabolic disorder
- Genetic abnormality in the functioning of an inflammasome
The diagnosis of fever is different in every class (continuous, transmitted, intermittent, busy). It is not always possible to find out the reasons for a long-standing fever. In these cases, the pyrexia of unknown origin is revealed.
A person may have a fever, if –
- The temperature of the mouth is more than 37.7 C (99.9 F).
- The temperature of the rectum (anus) is more than 37.5-38.3 C (100-101 F).
- The temperature inside the arm or inside the mouth is more than 37.2 C (99 F).
Fever is an indication rather than a disease. When the doctor confirms that body temperature is higher than normal temperature, then they suggest definite clinical trials, which can be determined on the basis of other symptoms. This includes blood tests, urine tests, X-rays and other imaging scans.
Treatment the fever
There are several ways to reduce fever. In general, it is possible to use ibuprofen or acetaminophen to reduce the pyrexia. Both medicines help in controlling pain and reducing pyrexia. Alternating both medicines will be relieved by alternating food and taking a medication will reduce the likelihood of accidental overdose. Occasionally, to prevent fever, both acetaminophen and ibuprofen may need to be taken together. Drying with cold water or having a cold towel on the skin (body) helps in reducing the fever. The deliberate cold fluid also removes and cools the patient immediately.
Aspirin medicine is never chosen first to reduce pyrexia. It should not be used on children at all. High doses of aspirin can prove toxic to the elderly or may cause illness such as Ray’s syndrome in children. Aspirin medicine should not be given to persons 18 years of age or younger unless prescribed by a physician.
Ibuprofen prevents the hypothalamus from increasing body temperature. You can buy this medicine 200 mg tablets from the drug store. It is okay to take one or two tablets every four hours to reduce body temperature. Use this medication at least. Children’s dose is based on their weight.
Side effects of ibuprofen include nausea and vomiting. After eating this medicine, they can be stopped by taking this medicine. The rare side effects include diarrhea, constipation, heartache, and stomachache. Persons with the stomach ulcer or kidney disease, pregnant women and people who are allergic to aspirin should avoid ibuprofen consumption.
Acetaminophen is also effective in reducing pyrexia. It has 325 milligrams or 500 milligrams of tablets at the drug store. This drug is also available in liquid form. One or two tablets should be used every four hours to remove the pyrexia. Like many other drugs, the children’s dose is based on their weight. The total doses taken by the adults in 24 hours should not exceed 3 grams (equal to six tablets of 500 milligrams).
Its side effects are rarely seen, but some people are allergic to the medicine. The excessive dose can cause liver failure. Therefore people suffering from liver disease and those people who have been drinking alcohol for a long time should avoid this medicine.
Common brand names of acetaminophen are Aspirin Free Anacin, Feverall, Genapap, Panadol, Tempra, and Tylenol. For the specific material described in the form of acetaminophen that is present in that medicine, read the drug label. Many other medicines contain the amount of acetaminophen which is in combination with any other medicines. Therefore, to ensure that the medicines should be checked, the total dosage taken in 24 hours should not be more than 3 grams mixed with combined medicines.
Any person with pyrexia can have dehydration, so take as much as possible of fluid content. Trying to cool the skin may make the person feel more uncomfortable. It can also cause shivering, which actually increases body temperature. This happens when the fever is caused by an infection. Apart from this, its treatment depends on the cause of the fever and its symptoms. Symptoms of a common cold can be treated at home only by medicines.
If the fever is due to hot weather or overstress (for example, heat stroke, hypothermia and heat exhaustion), its treatment technique is different from any other fever. Neither acetaminophen nor ibuprofen in such a fever will be effective. In such a situation, the person should immediately calm down. If the person becomes confused or unconscious then he/she should seek immediate emergency medical help. While waiting for help, remove the patient from the warm environment and take off the clothes immediately. In such a situation, the body should be cooled with wet sponges. Keep the fan near the patient, so that its air can reach the person directly.
Treatment of pyrexia depends on its causes. In most cases, acetaminophen or ibuprofen pills can be given to reduce the pyrexia of hyperthermia (see above home remedies). To prevent dehydration, fluids can be given by mouth if necessary.
Viral diseases are usually cured without medical treatment. However, medicines can be given to overcome specific symptoms. These medicines help in reducing pyrexia, reducing swelling and sore throat, and controlling the running nose. Intravenous fluids and medicines may be required to prevent viruses that cause vomiting and diarrhea. These medicines also help to prevent diarrhea and nausea. Some viral diseases can be treated with antiviral medicines. Examples of herpes and influenza virus are examples.
Specific antibiotics are required for bacterial diseases. This depends on the type of antibiotic bacteria or the place of its presence in the body. Doctors determine whether a person is admitted to a hospital or sent home. This decision depends on the person’s illness and its health status.
Most fungal infections can be treated with antifungal drugs.
When the medicine is closed, the pyrexia caused by that medicine is also eliminated.
When the sick person is interrupted by the immune system, it will be evaluated immediately. A person suffering from hyperthermia will be admitted to the hospital.
Most fevers are cured within a few days after appropriate treatment. To properly treat the cause of the pyrexia, follow the advice given by the health expert. In this early stage of fever, it can be diagnosed in a few days or weeks. It depends on the cause of the pyrexia.
If the symptoms of the fever become serious even after the treatment and the pyrexia should not last for three days or if the treatment without fever remained for a week, then immediately see the doctor.
Risks and complications of fever
Fever usually does not cause serious complications, but sudden pyrexia or long-term pyrexia can be dangerous. This can be the following complications –
- The hallucination – Increasing body temperature in adults is more likely to be confused than children. It is possible that your child can begin to see things that are not really due to pyrexia (such as watching the doll flying in its room or walking on the bugs on its own). When there is a temperature of 102 degrees F or greater, there is more chance of confusion.
- Fever – When fever attacks occur in children, during which time their body starts to get cramped, cramped or shivering, which is especially due to pyrexia in children. Approximately 2 to 5 percent of children experience this fever tour. Those 30 to 40 percent of the children who have had a pyrexia in the first place can experience such a tour again.
- Dehydration – Dehydration can be light, medium or high. The fluid that emits from your body, it is necessary to complete the shortcomings immediately. Dehydration occurs when you are unable to take serious diarrhea, pyrexia, bleeding in the stool or any other fluid without any vomiting or vomiting for 24 hours.
Many types of infections can be the cause of the pyrexia. If untreated, then there may be serious problems. It is important to treat the underlying causes of the pyrexia in the situations described above.
