Viral fever is a common illness that many of us have experienced at some point. It can be distressing, with symptoms like a high fever, body aches, and all-over fatigue. These symptoms are unpleasant, but they indicate your immune system is fighting the infection. What exactly is happening when we get a viral fever? How does the immune system respond to viral infections? Let's explore the remarkable responses of the immune system in combating viral fever and your body's natural defense mechanisms.
A virus infection causes viral fever, which is an increase in body temperature. Tiny organisms, known as viruses, enter your cells and begin replicating to cause disease. Viruses that cause fevers are usually the ones that cause the flu, the common cold, dengue fever, and other diseases spread by viruses.
Viral fevers are usually self-limiting, and most of them just wear off on their own as the body's immune system fights off the infection. However, severe cases may need medical intervention, especially if the fever doesn't go away even after a couple of days or if it is accompanied by other troubling symptoms.
Worldwide and Indian-Specific Stats
According to the World Health Organization, 16% of the 57 million deaths globally each year are from viral infectious diseases. Among the symptoms that are present with a viral illness, fevers are prominent.
According to an estimate by the Indian Council of Medical Research, about 30% of all fevers in the country result from viral infections. The diseases that are mostly widespread include dengue, chikungunya, and seasonal flu.
How the Immune System Responds to Viral Infections
Immune system protects me from viruses. Cells, tissues, and organs work together to attack and destroy pathogens. Here is how your immune system would respond if you had a viral infection:
1. Virus identification
Once a virus gets into the body, the defense system's first job is to determine that something is wrong. Antigens, highly specialized cells, present themselves by scouting the body like patrols to find foreign invaders. When they encounter a virus, they notify other cells of the immune system, thereby initiating an immune reaction against it.
2. White blood cell activation
B cells and T cells are the main types of white blood cells that the immune system induces after it recognizes the virus. T cells can actually directly kill the infected cells, while B cells produce antibodies capable of detecting the virus and inactivating it.
3. Production of antibodies
Antibodies are proteins designed to bind to specific viruses. Once the B cells produce the antibodies, they bind to the virus and signal for its destruction. This makes it unable to infect other cells, and the immune system gets rid of the infection.
4. Inflammation and fever
Cytokines help coordinate the immune response; they give signals that result in inflammation and fever. It might be uncomfortable to have a fever, but it's the primary line of defense for fighting viruses.
5. Memory Cells: Long-Term Protection
After eliminating the virus, the immune system produces memory cells. Memory cells help your immune system respond quickly to the same infection later in life. That is why you may develop immunity to a virus after recovering from it.
Indications of a Viral Fever and Immune Reaction
Most potential viral physiological symptoms cause the immune system to fight infection. Fever is one of the most common indications of these disorders, as high temperatures help the virus progress slowly in the body.
Generalized Fatigue and Weakness: Often when you suffer from this disease, your body tends to engage a high amount of energy in providing the vital body functions of supporting the immune system, resulting in a generally fatigued feeling at such times.
Bodyaches: Cytokines-induced inflammation can cause muscle and joint pains.
Chills: The shivering is due to the body trying to jack up the temperature and make the condition incompatible with the virus.
Even though these are the symptoms of high activity in the defense system, there are a few steps that can help the body repair itself early.Treatment Options for Viral Fever
While most viral fevers resolve on their own with proper rest and care, there are times when medical intervention is necessary. If your fever persists for several days, is very high, or is accompanied by severe symptoms, it's essential to seek professional care.
Management of Viral Fever
While most viral fevers resolve on their own with good rest and care, a few require medication. If your fever has lasted several days, is high, and other symptoms are severe, seek medical attention.
