Composition of influenza A virus h 1n 1

In March 2009, influenza A (H 1N 1) occurred in Mexico and the United States one after another. Its virus is influenza A virus, and its subtype is H 1N 1 swine flu virus, which contains gene fragments of three influenza viruses: swine flu, avian flu and human flu. This is a new swine flu virus, which may infect humans.

View list

1. It is impossible for human beings to be kind to animals, and the harsh feeding environment provides opportunities for the growth and variation of the virus. Humans don't care about the environment and abuse antibiotics.

2. The plundering and destruction of nature by human beings is becoming more and more serious. Studies have proved that 66% of infectious diseases are spread by animals.

3. Theory of accelerated virus mutation: The acceleration of virus mutation and the leap of "species barrier" make the danger faced by human beings more and more serious.

Viruses are smarter than humans: viruses constantly look for human weaknesses and take advantage of them. With the continuous struggle between human beings and viruses, the fighting power of viruses is getting stronger and stronger.

5. The global public health prevention mechanism should be improved, scientific prevention needs global cooperation, and scientific and technological development needs to respect nature.

6. Climate change theory: Climate change promotes the occurrence and spread of animal infectious diseases. Global climate change will certainly cause some bacteria to change, so that the danger of human beings is not only at the macro level, but also in the micro world.

Focus on key words

The life cost of biological virus ecological plunder man-made conspiracy is harmonious.

Focus interpretation

Humans are changing the earth, but behind these changes, benign qualitative changes and dangerous hidden dangers have been triggered. With the passage of time, many new diseases and terms have appeared. These seemingly unfamiliar but so familiar germs like SARS, avian influenza and influenza A (H 1N 1) suddenly hit like a hurricane, and all these are changing us.

This social focus deserves our attention. It involves man and nature, global issues, public health, ecological protection, environment, crisis, introspection, disaster, cherish, respect, shock, life, cooperation and harmony.

[Application example]

Topic 1 Man and Nature

Nature is the habitat of animals and plants, the origin of life and the source of everything for us.

Life is between heaven and earth, living in nature. We bravely walked from the wild age to the civilized century.

There is a great relationship between man and nature. In nature, human wisdom has created economic miracles, while ignorance and greed have left terrible consequences. Now the earth gives a groan of pain: environmental pollution, ecological deterioration and rampant viruses. All this is worth pondering. SARS in 2003, avian flu in 2004 and influenza A today all make us think deeply about how human beings should treat nature. How do humans live in harmony with nature?

Perhaps it is a simple answer: be kind to nature and live in harmony. Be kind to everything, just like being kind to our friends; Saving the earth means saving our home! The main idea of harmony between man and nature is that man and nature are interrelated, interdependent and harmonious.

Topic 2 Disaster

In the face of the arrival of "influenza A H 1N 1", perhaps we think of a gray word "disaster". In fact, we have suffered countless disasters. El Nino, greenhouse effect, global warming, tsunami, SARS, and now influenza A, every disaster here stings the fragile nerves of human beings. Why on earth is this?

Maybe it is the punishment of nature, maybe it is the punishment of the earth. What is it? Why are there so many disasters? We are considering this matter. After entering the industrial age, human beings plundered extensively, causing serious industrial pollution and obvious global greenhouse effect. The progress of mankind is based on plundering nature. Killing other species at will, seals in the Arctic Ocean are skinned, blue whales in the ocean are slaughtered, rare species in the mountains are cooked, and so on. Man's appetite is based on killing living things. To sum up simply, environmental damage and ecological imbalance will lead to frequent disasters.

Lower your head, arrogant human, and take a long-term view; Swallow your saliva, greedy human, and put your taste in a normal position, otherwise human beings can only bear the punishment of the earth themselves-disasters occur frequently.

Theme 3 Reflection

Introspection is the source of human progress. Lack of self-reflection is a common weakness of human beings, which is not limited to the arrogance of nature, but more importantly, there is always reason to excuse oneself for mistakes.

Abnormal climate, serious three wastes, epidemic diseases, frequent disasters and environmental deterioration caused by industry and modern social lifestyle have become hot topics and difficult problems all over the world. When people take actions one after another to solve various specific environmental protection problems, human beings need to really reflect on themselves. Because of the arrogance of nature, environmental pollution and destruction have contributed to more bacterial variation. Human egoism and blind behavior of ignoring nature have become the sword of Damocles hanging over human heads. How many viruses mutate? How much effort will mankind have to make to reap the consequences? All this tells us that we must calm down and seriously reflect on the relationship between man and nature, the problems of natural environment, the relationship between industry and nature, and human weaknesses.

From the fundamental content, fundamental reason and fundamental relationship, we reflect on human philosophy and our humanity.

Topic 4 Life

Life is precious, so are countless life forms on the earth. Life on the earth is inseparable, and the interconnection of life creates a colorful world.

The colorful earth world is full of threats and crises of various factors all the time, and these threats and crises are easily destroyed by life. The Spanish flu in history claimed 40,000-50,000 lives; The "Asian flu" caused at least 1 10,000 people in the world to die from this disaster; "Hong Kong Influenza" has affected at least 55 countries and regions around the world, causing 654.38+0.5-20,000 deaths worldwide. The progress of modern medicine still can't save more than 900 lives of SARS in 2003. Today, with the rapid variation of microorganisms, human life is extremely fragile. Isn't this fragility destroying the refraction of other lives?

Life needs harmony, and life also needs harmony.

Theme 5 Public health

Public health is not a trivial matter, but a major event related to environmental protection and people's livelihood. Strive to create a clean and hygienic environment and build a safety barrier for people's health and economic development.

Environmental sanitation is directly related to human health and people's livelihood. To be well-off, we must be healthy first; Health is better than wealth. The cleaner the environment, the less soil and activity space for viruses and germs that endanger human health. Instead, it breeds and spreads, bares its teeth and exposes lost face, posing a serious threat to mankind. Just like the SARS virus that was once rampant for a while, it must be an environment that provided a "climate" for its popularity. We must do a good job in education, publicity and supervision, and start from the foundation.

Public health is an important part of the construction of spiritual civilization, the embodiment of patriotism, love for home and self-love, and the foundation of enriching the country and strengthening the people.

Influenza Crisis and Public Health

A butterfly flapping its wings in Brazil may cause a tornado in Texas, USA. This effect is very similar to the influenza A (H1N1) that we are facing today-how to prevent the unsafe factors represented by a "pig, dog, chicken, duck and goose" virus from crushing, destroying the development achievements of our society or crushing our "global" civilization construction?

Public health is a public utility related to the public health of a country or region. The specific contents of public health include the prevention, monitoring and treatment of major diseases, especially infectious diseases; Supervise and control food, medicine and public health, as well as related health promotion, health education and immunization. For example, the control, prevention and treatment of SARS are typical public health functions.

Influenza H 1N 1 has caused a great sensation since this talon reached the earth and our world. From Moscow, the United States, Japan ... to China, all of them were spared, which shows that it spread quickly. Although we can use the existing medical technology to prevent and cure it, it is still frightening. The most ridiculous thing is that some people don't eat pork because of this. However, these are not my focus. What worries me and makes me sad is:

When our country found the first infected person, it was a Sichuanese who came back from abroad. Most of what I heard was severe criticism from everyone, which made me extremely sad. It is a good thing and a happy event to come back from abroad. But because I didn't even know I was infected, I made a mess and became a sad thing. Originally, I thought we should sympathize with him and help him. However, many people say, "Don't go abroad!" "This also makes us feel uneasy." ……

So writing this article, I want to call on everyone to cheer for them.

Unfortunately, they were infected, and now they are isolated. They can't see their relatives, lose their freedom, and are also very painful and unwilling. So let's give them courage and strength! Let's wish them a speedy recovery!
