- Common Cold
and Influenza
- The Difference between these two Ailments
By Knut Holt
-
Both common cold and flu give
symptoms from the ear, nose and throat, fever and symptoms from
the rest of the body, and the symptoms of both diseases can vary
between mild and very bad. By common cold, the symptoms from
the windpipe comes first and remains as the main symptoms.
By flu fever, pain in the rest
of the body, nausea, feeling of weakness and other general symptoms
are predominant. Symptoms from the windpipe are usually milder,
but can gradually get somewhat worse. The symptoms from the windpipe
may sometimes nearly lack.

The Causes and Symptoms of
Common Cold
The common cold is caused by
a large variety of viruses, which mutate quite frequently during
reproduction, resulting in constantly changing virus strains.
The common cold is generally
transmitted when drops coming out when a person sneezes or coughs
get airborne and then are inhaled by another person. Transmission
by direct contact with a sick person is also frequent. Between
one-third and one-half of all people exposed to cold viruses
become infected and develop symptoms after 1-2 days.
The symptoms from the windpipe
are the strongest by the common cold:
- The throat feels sore, and
a sore throat is often the starting symptom.

|
- There will then be increased
secretions of mucus from the nose, resulting in running nose
and drier secretions building up in the nose.
- The throat will also secrete
more mucus, resulting in a wheezing sound, and possibly building
up of drier secretions.
- There will be swelling in the
nose and throat.
- Cough and sneezing are important
symptoms of the common cold. These reactions are stimulated by
the building up of secretions and of the swelling in the windpipe.
There may also be mild symptoms
from the rest of the body.
- Mild to severe headache is
common.
- A mild fever may occur.
- Some persons experience a little
neck stiffness and pain in the neck when trying to flex it, but
this symptom must not be great. If this symptom is great, it
can be a sign of meningitis, a very serious disease.
The Prevention and Treatment
of Common Cold
Staying away from people being
sick and strict washing habits can prevent the transmission of
common cold, but it is difficult to carry through a strict enough
regime of this sort in a populated society.
Because of the frequent variations
of viruses causing common cold, successful immunization has not
been developed.
The immune system of the body
usually manages to beat down the infection within some days.
By having the common cold one should hold an activity level that
feels comfortable. It is not necessary to strictly restrict the
daily activities level.
High doses of Vitamin C have
been proven to help prevent colds and gets rid of the cold faster,
but the doses that must be used are impractically high if Vitamin
C is used alone. However, a combination of lower doses of Vitamin
C with other natural substances may be useful.
Common treatments of colds have
the aim of relieving symptoms and of strengthening the immune
system so that it can beat the infection better. Pain killers
such as aspirin and paracetamol relieve the pain by the common
cold effectively, and is the most common treatment for this disease.
However, both drugs can give adverse reactions if they are used
in greater amounts than recommended and even recommended doses
can sometimes give dangerous effects.
Aspirin can cause internal bleeding
and both aspirin and paracetamol can cause liver damage. For
children and teens it is advised to use paracetamol, because
the liver damage caused when young people take aspirin can be
very severe. The drugs should therefore be used with caution
and not for a long period of time.
Drugs to loosen mucus, to decrease
swelling, to decrease mucus production or to suppress the cough
reflex can be effective to relieve symptoms. These drugs are
often made to mainly loosen mucus or mainly suppress exaggerated
cough, but these two effects can be blended in the same drug.
These drugs may be liquid, be prepared as nasal spray or as tablets
to suck on. To choose the right drug for your child or yourself,
you must examine to find out what are the main symptoms: Mucus
production, whether the mucus is loose or hard, swelling or exaggerated
cough.
Steam inhaling is a traditional
treatment long used in many countries. The treatment can help
loosen the mucus so that the windpipe is easily cleared by cough.
The treatment may also to some extent destroy the virus.
The drug Pleconaril is meant
to attack the viruses causing the majority of common colds, picornaviruses.
The drug has been developed by ViroPharma Incorporated and Schering.
The drug is available in oral form and inter-nasal formulations
are being developed, but the efficacy of the drug is not clearly
established and the drug is not yet approved for general use.
Interferons are used nasally
in Eastern Europe to treat common cold. Interfeons are natural
proteins than regulate the function of the immune system.
There are herbal and mineral
supplements on the marked that may strengthen the immune system
and thus prevent colds from occurring, ameliorate the cold if
it still occurs, and help the body to fight down the disease
faster. These supplements often contain extracts of Echinacea
Angustifolia. Treatment with this herb should not exceed two
weeks.
The Causes, Symptoms and Complications
of Influenza
Like colds, influenza is caused
by virus strains that mutate frequently, but there tends to be
one main virus strain each year that spreads throughout the globe.
The transmission of the disease
occurs by secretions from sick people. These secretions can be
carried as drops through the air, contaminate surfaces people
touch, or get into the food. Symptoms start one to four days
after the virus has entered the body.
Flu often begins as a diffused
lack of wellness that persists for some hours, and sometimes
for a couple of days. Sometimes the flu does not progress past
this stage. However, after some time the symptoms often suddenly
get worse with a great degree of general discomfort. By flu the
symptoms from the windpipe are the same as by common cold, but
they are weaker:
- The throat or nose feels sore,
but usually mildly.
- There can be some increased
secretions from the nose and throat.
- There will be swelling in the
nose and throat.
- Cough and sneezing are symptoms.
Symptoms from the rest of
the body are the strongest by flu. The symptoms can be distributed
throughout the whole body:
- Flu often gives high fever.
High fever is the most important symptom to separate influenza
from the common cold.
- In spite of the fever, there
is often a feeling of coldness in some parts of the body or of
general coldness.
- There will be nausea, often
severe, and often vomiting. Severe nausea and vomiting are also
good indications of influenza, especially by children and teens.
- There is often a marked feeling
of tiredness and general weakness.
- Mild to severe headache is
common.
- Stomach ache and digestive
disturbances often occur by flu.
- Aching around in the body,
for example in muscles and around joints is common.
- Some people experience a little
neck stiffness and pain in the neck when trying to flex it, but
this symptom must not be great. If these symptoms are distinct,
the disease can be meningitis.
- The eyes can be red and irritated.
- Also skin redness can occur.
Having the flu decreases the
resistance against other viral and bacterial diseases substantially,
especially if one does not get enough rest and comfort when having
the flu. Lung infection and throat infection by bacteria are
common complications by flu.
The Prevention and Treatment
of Influenza
As with the common cold, staying
away from people being sick and a strict washing regime may also
prevent the transmission of the influenza virus, but such a regime
is difficult to carry through.
It is often possible to prevent
the flu with a vaccination. However there are many strains of
the flu viruses, and therefore the vaccination must be given
exactly against that strain being epidemic at any given time.
By flu it is important to reduce
the activity level and keep oneself warm and comfortable until
all the symptoms have resided. By severe symptoms, bed rest is
recommended. Straining and stressing during a flu episode easily
result in an aggravated disease and additional bacterial or viral
infections.
It is advised to stay away from
tobacco when you have the flu.
Aspirin or paracetamol can be
used to relieve the pain and bring down the fever. As by cold,
paracetamol is commonly recommended, especially for children
and teens. The drugs should not be taken in higher doses than
recommended and even recommended does shall be used with caution,
and not too long.
There are modern drugs that help
against the proliferation of some strains of influenza virus
in the body, and thereby alleviate the disease and shorten the
time it takes to get rid of the disease. The two classes of anti-virals
are neuraminidase inhibitors and M2 inhibitors (adamantane derivatives).
Neuraminidase inhibitors are most often preferred, for example
the drug Tamiflu. These inhibit the action of the enzyme neuramidase
that the virus uses. There is a reluctance to use these drugs
because strains of virus not susceptible to the drug can develop,
and the stores of the drug can easily get short with extensive
use.
Drugs to decrease swelling, inhibit
mucus production, loosen mucus and suppress coughs can also be
used by influenza as by common cold.
The same natural supplements
used to improve the immune system against colds may also be of
help to prevent flu and to help the body to overcome the disease
faster, like supplements with Echinacea and vitamin c. Some herbs
in the genus Scutellaria (skullcaps) contain a natural neuramidase
inhibitor and may also help against flu. Scullcap is often prepared
as tea.
Distinguish Cold and Flu from
Meningitis
Meningitis is a serious disease
that requires immediate treatment. Meningitis may begin with
the same symptoms as cold and flu. There are however two symptoms
that strongly suggest meningitis:
By meningitis there is often
severe neck stiffness. If bending down the neck is very difficult
and causes severe pain, the condition may be meningitis.
The other symptom is red spots
in the skin that do not get pale when pressing at them. These
spots can occur anywhere on the body.
The Importance of Checking
a Person Having Cold or Flu-Like Symptoms
When some poeple, and especially
a child, gets sick with cold or flu-like symptoms it is necessary
to measure the temperature, check for neck stiffness and to look
at the whole body to detect any red spots. These checks should
be done several times each 24 hours. In this way one more easily
distinguishes between common cold and flu, and meningitis is
more easily discovered in time. |
