Fever

Fever is the natural response to infection.
Pyrexia
Pyrexia refers to an increase in body temperature resulting in a fever. A person
with a fever is said to be febrile. When the body temperature is not raised the
person is described as being apyrexial (the prefix ‘a’ or ‘an’ always means without).
It is the hypothalamus which regulates body temperature by comparing the
temperature of the blood circulating through the structure with a set point,
usually between 36.5-37oC. When blood temperature drops, the hypothalamus
initiates mechanisms to increase body temperature; conversely when blood
temperature rises above the set point, heat loss mechanisms are initiated. In a
fever the set point is increased to a new higher setting.
Cause of fevers
Fevers are most commonly caused by infection but also occur after tissue damage
which may be caused by trauma, surgery or disease processes. For example, pyrexia
is not uncommon after a myocardial infarction when part of the myocardium
is damaged by an occlusion of the coronary arterial blood supply. Neoplasm is
another possible cause and fever may be an early sign of a developing cancer.
Infection is caused by the presence of microorganisms, such as bacteria or
viruses, in a tissue. As the presence of bacteria or viruses causes a febrile response
these infectious agents are often referred to as exogenous pyrogens. Exogenous
means the cause is from outside the body, the infection comes from the
environment. ‘Pyro’ literally means fire or heat, ‘gen’ refers to genesis which
means beginning, so a pyrogen is something which ‘begins heat’.
Leucocytes (white blood cells) are able to detect the presence of infectious
agents in a tissue. Upon detecting infection these white cells, especially the
macrophages, respond by producing cytokines. Cytokines are hormones
produced by individual cells which have the potential to affect other cells or
tissues in the body. Two of the cytokines produced by macrophages in response
to the presence of infection are interleukins (ILs) and tumour necrosis factor
(TNF). It is the presence of these cytokines in the blood that increase the set
point of the hypothalamus in order to generate a fever. Because these pyrogenic
cytokines are released from the body’s own cells they are referred to as
endogenous pyrogens.
Fever increases immune function
By being able to recognise these cytokines the hypothalamus becomes aware of
the presence of infection or damaged tissue. This allows for the initiation of a fever as part of the systemic response to infection. It has been suggested that
pathogenic microorganisms are less viable at febrile temperatures. While there
is some truth in this for some organisms, the main reason fever is generated is
to increase the efficiency of the immune system.
It has been demonstrated that neutrophils exhibit greater motility and
bacterial killing activity as the temperature rises from 36 up to 40oC. Some
studies indicate that macrophages function more efficiently at about 39oC. As
neutrophils and macrophages are the most active phagocytic cells it follows
that this process of white cells ‘eating’ bacteria and viruses works most efficiently
at these increased temperatures. At temperatures around 39oC other activities
of the immune system such as release of interferons, release of cytokines,
activation of complement and the activity of lymphocytes have all been shown
to be enhanced. Pyrexial temperatures also increase the likelihood that virally
infected cells will self destruct, therefore killing the viral particles they contain.
If the immune system is working more efficiently as a result of a fever, then
the infection will be combated more aggressively and quickly. This will in turn
limit the course of the infection, promoting rapid recovery. As infection is
efficiently combated by the immune system in febrile patients, tissue damage as
a result of the infection is less likely to occur. In addition to these benefits of
fever there will also be an increase in the metabolic rate of the body which will
allow tissues to regenerate more rapidly.

That would be fascinating. I remember when I was 6 or so I got chickenpox. My fever went so high that I wasnt thinking straight.

Most people jump the gun with fevers. People do the same thing about swelling. Swelling is the natural defense of the body. Twist a knee or other joint bad enough, and it swells. Most people rush to bring down swelling but it's the body's natural reaction . It's a protection. In indigenous cultures they had created natural concoctions to create a fever. Some also would have the sick person sit in a sweat lodge. This is designed to raise the body temperature.

Yes, Kelli, we can and should all pay very close attention to the following weeks! I know that any attempts to “extend” that ship quarantine would have resulted in anarchy on that ship, in my opinion, despite the fact that since that initial 14 day start of the ship’s quarantine, we have become aware of a possible 24-28 day incubation period AND the aerosolized nature of the virus’s spread. It was the best Japan knew to do at the time, I believe. Today’s actions, however, go AGAINST Japan should know to do to protect the masses.

Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground.”

Thank-you, John. This is the first time that I have seen this explained simply and clearly. I wish that someone had told me this information 50 years ago, when I had glandular fever. The medics dosed me up on antipyretics, which must have prolonged the problem for weeks.

[@deeshankar3868]

How is fever in children different than in adults? If fever is body’s way of amping up the immune system and fighting off the bacteria/viruses then we should let a fever run it’s course in children too. Fever is generally beneficial and a sign that our immune system is in full action. I am also curious about the ‘crisis point.’ I would definitely like to hear your views on this.

[@ZeroMass]

I'd like to know what effect a prolonged hot bath, sauna, or hot tub has on influenza etc if used to increase ones body temp in the early stages of illness. For years I've always taken many hot baths when the body aches hit. I notice that I recover faster. Regarding children, my two young kids get a fever at least once per season, we have never suppressed the fever with meds and monitored closely.. There is a statistical increase in deaths when Tylenol etc is used to break the fever in kids..

[@ittsacrazyworld]

Deepali Shankar One difference is that children are more likely to have a febrile seizure. Febrile seizures are rare in adults.

[@ZeroMass]

@Tiger Momma hot baths also increase circulation, increase metabolism, washes bacteria off your body and in turn reduces the load on your immune system. I did a test the other day in a bath of 43 deg C, a temperature probe in my armpit and was able to bring my temp up from 37c (average body temps) and got it up to 41c in less than a half hour. This would otherwise be fever temps, and according to the good doctor, inhospitable to viruses which slows its reproduction rate. Question remains weather or not this allows your immune system more time to attack and rid these tiny invaders...?

[@4nd3rzzon]

When I get sick I often spends hours in the bath, back in 2016 when my appendix got infected I spent over 12h in the bath before being brought to the hospital, I was really close to death because of sepsis

Dr. John Campbell can you do a video about Fever in kids and when you need to act when Fever is to high or for a long period of time? what i am trying to ask is when is the moment that you run to the hospital because of Fever.

[@curiousobserver4525]

As a parent, I've always felt that 39Celcius was tops for children, 40celcius can cause damage. Giving plenty of fluids/electrolytes keeps the child urinating, thus removing heat, cold water in - hot urine out, helps to prevent the fever running too high. Luke warm showers/baths, never cold help also. Cold will cause the pores to close and keep the heat in. If I feel the temp is uncontrollable naturally, parents instinct based on the behaviour of child as well, I will start to give panadol and if still too high I will alternate between panadol and ibuprofin every 2 hours until its under 39. Then i will hold off on medications and see if it settles. Not a rule book, but it may help.

Dr Campbell, could the way a person gets infected with SARS CoV-2 (COVID-19), meaning if they contracted it through inhalation vs touching their eyes or mouths result in an asymptomatic infection? I was thinking about you explanation of the ACE receptors that this virus target and how they are located in deep inside the lower respiratory system. My thinking is only those who inhale it will have it travel to the lungs. Others my get it but the virus may not reach the lungs therefor not present the pneumonia symptoms.

Whenever I have a fever, I lay in bed with a few blankets over me. I only drink warm liquids. This way my body can easily maintain the fever without burning lots of calories and exhausting my body. I usually feel better within 24 hours. Often I fall asleep and feel better when I wake up several hours later. Use a thermometer to monitor your temperature so it doesn't get dangerously high. I never bother, but it's probably a good idea.
