Introduction:
Fever is a typical symptom of infection; it occurs as a result of the body's immune response to fight off the infection. Different types of fevers can be caused by different pathogens, such as bacteria, viruses, fungi, and parasites, and can affect different parts of the body, such as the respiratory system, urinary system, and gastrointestinal system. When an infection is detected by the body, different chemicals are produced by the body's immune system, such as cytokines, which can cause inflammation and activate the body's fever response.
Fever is a natural defense mechanism that guides the body to fight off the infection by raising the body's temperature and making it a less hospitable environment for the invading pathogen.
The severity and duration of a fever can vary depending on the type of infection and the immune system response of the infected person. In some cases, fever may be a mild symptom that resolves on its own, while in other cases it may be a sign of a more serious infection that requires proper medical attention and treatment.
What Are the Different Types of Fever in Infections?
Fever is a symptom of many different types of infections. Some types of fever that may occur with various types of infections are as follows:
-
Acute Fever: Acute fever usually develops suddenly and can last for a short time. It is commonly associated with acute infections such as flu, colds, and ear infections. Acute fever can also be caused by non-infectious conditions such as autoimmune diseases, inflammatory disorders, and medication side effects.
-
Chronic Fever: Chronic fever lasts for a longer period, usually about two weeks or more, and is associated with certain chronic infections such as tuberculosis or HIV (Human immunodeficiency virus).
-
Sustained Or Continuous Fever: In this type of fever, the temperature remains above the normal range and it does not show any fluctuations, examples are fever in bacterial endocarditis, typhoid fever, and urinary tract infections (UTIs).
-
Intermittent Fever: Intermittent type of fever usually occurs in cycles, the temperature of the body associated with this type of fever keeps on rising and falling over a while. Examples of intermittent fever are fever associated with malaria, septicemia, and bacterial infections.
-
Remittent Fever: It is a similar type of fever to intermittent fever, but fluctuations in temperature occur more widely and do not return to normal levels. It is often seen in infectious diseases such as dengue fever, typhoid fever, and septicemia.
-
Pel-Ebstein Fever: This fever is associated with Hodgkin's lymphoma and is characterized by fever cycles that last for one to two weeks.
-
Septic Fever: This type of fever occurs in response to a severe infection and is characterized by a high temperature and the fever does not respond to any antipyretic medication.
-
Postoperative Fever: Postoperative fever is associated with surgery and surgical site and is often caused by an infection at the surgical site.
What Are Common Signs and Symptoms Associated With Fever Caused by Infection?
Fever itself is a symptom of infection, and it can be accompanied by a range of symptoms. Some common symptoms are:
-
Elevated Body Temperature: A fever is defined as a body temperature above the normal range, which is generally considered to be 98.6 degrees Fahrenheit (37 degrees Celsius) taken orally. A fever in infection may range from a mild elevation of temperature to a high fever of over 102 degrees Fahrenheit (38.9 degrees Celsius) or more.
-
Chills: Chills may occur as the body tries to generate heat to increase its temperature to fight off the infection.
-
Headache: Headaches are symptoms associated with fever in an infection, and can be caused by the release of inflammatory chemicals in the body.
-
Body Aches And Muscle Pain: Body aches and pains throughout the body are common symptoms of fever in an infection, and can be caused by inflammation and muscle tension.
-
Fatigue: Fatigue and weakness are common symptoms of fever in an infection, and can be caused by the body's immune response and metabolic changes.
-
Sweating: Sweating is a common symptom of fever in an infection, and can be caused by the body's attempt to cool down by releasing heat through the skin. It is performed by the glands present under the skin.
-
Loss of Appetite: A loss of appetite is a common symptom of fever in an infection, as the body is more focused to prioritize the energy towards the immune response rather than digestion.
If the fever persists for a longer time with symptoms like difficulty breathing, persistent high fever, chest pain, or confusion, it is better to visit a healthcare professional immediately.
How to Treat Fever in an Infection?
The treatment of fever in an infection depends on the cause of the infection, the severity of the fever, the individual's health, and any underlying diseases. However, general measures that can help manage fever in infection are as follows:
-
Stay Hydrated: It is necessary to drink plenty of fluids such as water, fruit juice, or broth to prevent dehydration (a common complication of fever).
-
Rest: Trying to get adequate rest, as it can be a useful tool to conserve the body's energy and aid in healing.
-
Manage Temperature: Use of a cool compress, taking a cool bath or shower, or wearing light clothing can help to lower body temperature and relieve discomfort associated with the fever.
-
Medications: Over-the-counter (OTC) fever-reducing medications such as Acetaminophen or Ibuprofen help to lower body temperature and relieve symptoms such as headaches and body aches. It is important to follow the recommended dosage and consult a healthcare provider if there are any concerns or if the fever persists even after taking the medicines.
-
Addressing the Underlying Infection: Treating the underlying infection with antibiotics, antiviral medication, or other treatments may be necessary to resolve the fever. Visit the doctor for proper dosages and prescriptions.
Conclusion:
It is important to note that not all infections will cause a fever, and not all fevers are caused by infections. Other conditions can cause a fever, such as autoimmune disorders, certain medications, and even some types of cancer. If the fever lasts more than a few days or is accompanied by other symptoms, it is important to seek medical attention to determine the underlying cause.
