How did swine flu, which has been raging in the United States for more than a year, infected 60 million people and killed 10,000 people?
In our impression, it seems that we can call it a serious
epidemic, only the SARS in 2003, and this new type of pneumonia.
In fact, in 2009, there was an infectious disease that was
more serious than SARS, and everyone seemed to forget it.
In 2009, the H1N1 influenza virus that swept the world,
formerly known as human swine flu (hereinafter referred to as swine flu), has
infected tens of millions of people (too many patients, it is impossible to
count), of which the United States has an estimated 60.8 million Cases, about
12,000 deaths, while China has 127,000 cases and 800 deaths.
In comparison, the cases of "SARS": 8,069 people
are sick and 774 are dead globally.
Was the swine flu very horrible?
To put it simply, this swine flu virus strain is a peculiar
mixture, containing gene fragments of human influenza virus, avian influenza
virus and swine influenza virus. The symptoms of infected persons are similar
to those of ordinary influenza virus infected persons.
So don’t think it’s swine flu, it’s caused by Brother Two.
In order to avoid panic about pigs, the US Centers for
Disease Control and Prevention announced that the swine flu will be renamed to
"H1N1 flu" because the virus is not spread by pigs, so pigs can never
be carried back.
The second brother who was wronged
For the flu, it may be because of the name. People think that
it is just a common cold. Influenza, or flu for short.
If you think so, you are wrong.
The lethality of influenza is not inferior to the coronavirus
that caused SARS and this Wuhan pneumonia.
Since the record, the most severe human flu was the Spanish influenza,
which was considered the deadliest infectious disease in human history.
From the outbreak in 1918 to the end of 1920, in two years,
the Spanish flu caused approximately 1 billion people in the world to infect,
and about 40 to 50 million people died (the world ’s population was about 1.7
billion people at the time)
So don't underestimate the flu, its infection intensity is
better than other infectious diseases.
From March to April 2009, the first swine flu outbreak
occurred in Mexico and then spread to the whole world.
The United States near Mexico is certainly not immune, and
has since become the worst affected area.
At 23:30 on June 11, 2009, the World Health Organization
confirmed a total of 27,737 confirmed cases of swine flu in 75 countries and
regions, including 141 deaths.
At 0:00 on June 12, 2009, the World Health Organization
announced that the alert level of the swine flu epidemic had been raised from 5
to the highest level of 6, indicating that the WHO believes that the "flu
pandemic" has arrived.
The last time WHO announced the "flu pandemic" was
in 1968, a new level 6 alert nearly half a century later.
This flu, which is worse than SARS, has also spread to China.
At a point of time schools issued a notice that all students would reduce their going out. Before
entering or leaving the school, they had to take a temperature measurement.
Each person issued a temperature needle, and reported the temperature to the counselor
every night before going to bed.
The school also distributed a bottle of alcoholic cotton to
everyone, and wiped whenever it felt unclean.
At that time, some classmates were sent to quarantine, and
the quarantine area was inside the school. Several classmates also
happily sent clothes and quilts to the quarantined classmates.
People all knew that
there was an influenza infection, but the atmosphere was completely different.
Swine flu has ravaged the world for more than a year.
The World Health Organization announced on August 10, 2010
that the swine flu pandemic has ended.
As the most severely affected area, what has the United States done?
The United States moves very quickly.
The first sample was found on April 15. The International
Health Organization was reported on April 18. The vaccine was developed on
April 21.
The disclosure was made to the public on April 23. On April 25, only
10 days after the first sample was discovered, WHO announced that the H1N1
epidemic became a public health emergency of international concern.
On April
26, the US government also announced a nationwide public health emergency, and
the US Centers for Disease Control and Prevention began to release national strategic
reserves
According to the U.S. Response Act, the process is over and
you should do what you need to do. Just wait.
Wait for the American people to adapt to the virus, wait for
the vaccine to be developed successfully, and wait for the virus to disappear
There is no closure, no "foot-stop", no suspension,
no suspension of classes, no extension of holidays.
What should the people of the United States do?
Don’t go out
if you are afraid of death, and go to the hospital if you are infected.
The number of infected people in the United States mentioned
at the beginning is actually an estimate, because the number is too much, and
only the upper and lower limits can be taken: 43.3 million to 89.3 million
cases.
Until 2011, the US Centers for Disease Control and Prevention
used the model to estimate 60.8 million infections, 274,000 hospitalizations,
and 12,469 deaths in the United States from April 12, 2009 to April 10, 2010
(model estimates). Among the hospitalized population, the mortality rate is
about 4.5%,
So has swine flu been eliminated till 2021?
No, the only infectious diseases that have been wiped out
throughout the world and human history have been smallpox.
"SARS" has not been eliminated, but we can't see it
now, and we don't know where it is hiding.
The plague is even more needless to say, in theory, there are
rats, there is plague.
In 2014, the plague broke out in Gansu Province, but it was
controlled in time. In addition, the outbreak site was Yumen. Unlike Wuhan, which
has no thoroughfare in nine provinces, the epidemic area was not very busy.
Almost 20% of Americans have contracted swine flu, which has
not been eliminated. Won’t Americans panic?
After a long time of panic, people were surprised.
At present, influenza A has become part of the annual
seasonal influenza in the United States, taking tens of thousands of American
lives every year.
Of course, the death statistics here are controversial,
according to Asian algorithm, even after death. According to the US
algorithm, after infection, it will cause other old diseases or complications
to cause death, then it can not be counted, only death from other causes.
