The name "influenza"
originated in the 15th century Italy. It was then that an epidemic occurred and was
called "influence of the stars." Virologists believe it all starts with
birds.More precisely, water fowl which is
defined by virologists as the reservoir for influenza.They carry almost all known types of influenza, having no ill effects,
sharing them with the other animals through their feces.All animals and human beings that acquire the flu probably get it originally
from birds.Viruses can only infect and take
over a cell if the right receptor is present.As
far as present research indicates, humans do not possess the receptor for the avian or
bird flu.Therefore, whats needed for
human infection is another species that has both human and avian flu receptors.This is where the pig comes into play.Having both human and avian receptors creates a
lot of influenza possibilities for the pig.The
process can be as simple as flu-contaminated bird feces dropping onto dirt in which the
pig is rolling around in.Thus, infecting the
pig.The infection virus is then passed to
the farmer.It is possible for a pig to
be infected with one kind of flu(human flu, then contracting the avian flue).The pig then simultaneously has two different
types ofinfluenza.When it proceeds to re-infect a human being, it
passes on a pig-bird-human influenza.
It
is not possible to get the influenza directly from the bird by
inhalation. Without the proper receptor, it is impossible for the virus to jump
species. However, In Asia and the Orient where we have been hearing about the avian
influenza virus being found in humans, one needs to remember that we are talking about
cultures where a lot of roosters are used for cock fighting. It is very possible for
those handling the roosters to get scratched and pecked with a little break in the skin
which leads to bleeding. That's one way they can get infected. Another way is
that it is very common for villagers in these developing countries to have roosters,
chickens and pigs (their livestock) tied up or running around freely. A lot of
houses are on stilts and the pigs and poultry are tied up under the house. During
cold tropical evenings it is also common to see people sleeping in hammocks, or whatever
they use as beds, outside amongst the pigs and the poultry. This is very common and
could very easily explain why we are hearing about humans being infected by the avian
influenza overseas.
Only 10%-20% of the American
population that gets sick every year during the "influenza season" actually have
the influenza virus. Other factors are involved such as molds, fungus,
severely compromised immune systems, stress...etc. The testing of the influenza
virus is not common. Diagnosis is based more on symptoms and less on actually
finding the influenza virus in the sick.
THE ANNUAL QUEST
Influenza
is that of a mutating virus.Thus, every year
the vaccine viral ingredient changes.By
their own admition, the process in which the Centers for Disease Control and Prevention
attempts to predict which influenza viruses will infect people in the United States is
based solely on guesswork.There
are three families of the influenza viruses WHO and CDC work with: A,
B and C.The C family
has never been used to formulate a vaccine because supposedly it is rarely detected in
humans. Nor has it ever been associated with an epidemic. A
is the most virulent strain (dangerous and potentially lethal) and C
is the least virulent.
Smith, Andrews and Laidlaw were the first to isolate the A
strain. They found it in ferrets in 1933. According to the Irish Examiner, it
was a British team that found the first virus in a man. Francis isolated the B
virus in 1936. But from where? In the same year, Burnet grew the virus on
chicken embryos.
After transmission, the virus
attaches to and penetrates the respiratory cells which includes the trachea and bronchi.
Then replication of the virus takes place. Next thing you know, you have a
multiplying viral situation resulting in the destruction of the host cells. The
respiratory cells. This is then followed by the typical symptoms which alert the
individual they may have caught an infection. The incubation period varies from 1-4
days. The severity of the infection depends on the individuals immune system.
A healthy individual will be able to get rid of it without major complications.
However, the more challenged the immune system already is, the greater risk of serious
complications possibly leading to hospitalization and or death. It is suggested that
aspirin not be used to alleviate the symptoms for infants, children or teenagers, because
of their risk for developing Reye syndrome.
With these viruses there are two
types of proteins (subtypes) which make up the outer protective coating of the viruses:
Hemagglutinin
(H)
Neuraminidase (N)
The viruses chosen for the vaccines
are named according to the type of proteins (subtypes) they carry.As you see in the chart there are at least
fifteen varieties of the (h) and nine of the (n).These
proteins can combine in every possible way to create a strain.Thus, it is realistically impossible for any
scientist to predict what strain will hit the public each year.
Influenza
viruses are cold-adapted. Therefore they are able to multiply quickly in the mucosa
of the nasal area.
A minimum of 48 hours is required to identify symptoms as the result of a viral
infection. Then an additional 1-2 days are needed to identify the virus type.
Physicians contribute this information by telephone on the number of cases and
hospitalizations. A subgroup of physicians swab from selected cases for
confirmation. Not all
suspecting cases are swabbed.
In order to "properly" diagnose an individual as having the influenza
infection, it is required for the individual to have a 4-fold rise in antibody titer.
This requires a rapid diagnostic testing for the influenza antigens.
Since these viruses are cold adapted one can correctly assume that they
also continue to multiply in the refrigerated vials during shipping and waiting to be
inoculated into the human body.
Dont forget, these viruses are
constantly mutating.That is why it is
realistically impossible for scientists to keep up with the mutation because what strains
were collected from the previous year have never been
conclusively documented to be the very same strain we see infecting individuals in the
following year.
The World Health Organization (WHO)
has an international influenza surveillance network to monitor prevalent and new emerging
viral strains.CDC receives weekly reports of
influenza activity in America. These reports are divided into four categories: no
cases, sporadic, regional (cases occuring in counties that collectively account for less
than 50% of state population), and widespread (cases that collectively account for over
5-% of the state population). Around the world, technicians affiliated with the CDC and
WHO collect influenza viruses from pigs and people.These
samples are sent off to the laboratories to be tested.The most suspecting cases are forwarded to the CDC or to the closest National
Influenza Center for full analysis.CDC then
attempts to predict which viruses will infect people in the United States the following
year.
It takes time to find chicken eggs
deemed clean. Meaning that they contain the fewest possible avian
contaminants. The snout of pigs or the nasal area of infected humans are swabbed
overseas. Then those cultures are brought back to the U.S. Out of these
cultures, a "broth" is made which is then injected into fertile chicken eggs
that have been stored in incubators. (Mind you, these are eggs from chickens which
are fed rendered animal waste. They are not your free range healthy chickens).
The eggs are then put back into the incubators where the embryos continue to grow
while, at the same time, they are "housing" the three strains of influenza
viruses. The eggs incubate until the embryos are literally teaming with influenza.
Then once the "desired amount" of viruses have been replicated, the
embryos are killed and treated with formaldehyde and mercury which are used to kill
contaminates and prevent mold growth and further contamination. There is also
aspartame, aluminum hydroxide, antibiotics...etc.
Because much time is needed to grow
the influenza viruses on the chicken embryos later collected for the final manufacturing
stages, the realistic scientists can not avoid the fact that this guess work is seriously
flawed because viral strains infecting individuals are mutations from the previous years
in which strains were obtained. Is science to assume the common lay person will
accept the unproven theory that these strains will help in prevention of infection from
the new mutation the following year?
Physicians brace themselves every
year due to anxiety and the reality in which they fear to admit that the vaccine has never
been conclusively documented to guarantee any level of immunity. Even scientists
have admitted their lack of confidence for the vaccine to provide immunity. In the
case of the Fujian Influenza it has been stated, Its impossible to predict
what will happen and, although the Fujian strain was on the radar screen when the decision
was made, we didnt have it in the laboratory. At that stage there were
question marks over it and I think the correct decision was made to go with the current
vaccine. Dr Jim McMenamin, of the Scottish Centre for Infection and Environmental
Health. How is it possible to make the "correct decision" with
that kind of information? It is not.
