The hottest material in 2009: background of influenza A (H 1N 1). In March 2009, influenza A (H 1N 1) occurred in Mexico and the United States, and its virus was influenza A virus, subtype swine influenza virus H 1N 1, including swine influenza, avian influenza and human influenza. List of opinions 1. It is impossible for human beings to be kind to animals, and the harsh breeding environment provides opportunities for the growth and variation of viruses.
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 perfected, scientific prevention needs global cooperation, and scientific and technological development needs great respect for 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. Key words: man and the natural environment, environmental protection, human crisis, global problems, public health introspection, biological virus, ecological plunder, man-made conspiracy, life cost, harmony and focus interpretation, human beings are changing the earth, but behind these changes, they have triggered benign qualitative changes and dangerous hidden dangers.
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 topics such as man and nature, global issues, public health, ecological protection, environment, crisis, introspection, disaster, cherish, respect, shock, life, cooperation and harmony. [Application example] Title 1 Man and nature are the habitats 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 has sent out painful * * *: 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 harmonious coexistence 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.
Topic 3 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 one's 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 common problems in 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.
2. According to the current situation of food safety in China, write a 730-word essay on the prevention and control of infectious diseases and food safety, analyze the causes of potential safety hazards and think about countermeasures.
With the globalization of economy, food hygiene and safety have become a hot topic of great concern. In recent years, some countries and regions in the world have witnessed vicious food safety incidents. With the extensive use of chemicals and new technologies in food processing, new food safety problems have emerged.
Although modern science and technology have developed to a considerable level, food-borne diseases have not been effectively controlled in both developed and developing countries, which still seriously endanger people's health and become one of the most concerned health problems in the world today. Therefore, in terms of the seriousness of food safety itself, it is still a top priority to attach importance to and vigorously solve this problem.
Key words: Current situation of food safety hazards and suggestions on food-borne diseases supervision 1. Foreword There is a saying in China: Food is the most important thing for the people. Food is the most basic material condition for human survival and development.
China has another saying: Illness comes from the mouth. Unsafe food quality will affect people's health.
Food safety is related to the life, survival and continuation of all mankind, and it is an important subject of human development. It is precisely because of the great potential of the food market that with the continuous improvement of people's living standards, China's food processing industry has made unprecedented development in recent years, making various new foods emerge one after another.
Every day, as long as we turn on the TV and read the newspaper, we can see a large number of various food advertisements. On the street, whether it is shopping malls, supermarkets or even street stalls, food occupies the main share of the market.
Recently, with the further improvement of transparency in all walks of life, food quality problems have been frequently exposed by the media, which directly leads to the safety of the food industry becoming a major theme that people are most concerned about. Nowadays, food safety has become a "big worry" for consumers in China, which is related to the health and safety of consumers and even the next generation, and is one of the most important threats to public health at present.
Therefore, paying attention to food safety has become an important aspect to measure people's quality of life, social management level and national legal system construction. When we see the problems of food safety in the world, we should understand the problems and shortcomings of China's food safety legal system. Relevant departments at all levels should attach great importance to this issue, further strengthen and improve China's food safety legal system, and keep pace with the times, which is particularly important and urgent at present.
Second, the current situation of food safety in China for a long time, reports on various inferior foods have almost become a major topic that we can see in the media every once in a while. For example, inferior milk powder, inferior flour, inferior rice, inferior bean products, dyed white stripes, water-injected meat, Sudan red and the melamine incident that is now raging, we can make a long list.
These frequently exposed food processing shady scenes are no longer unfamiliar to consumers. Supervision departments at all levels have never stopped law enforcement inspections, and they will intensify law enforcement inspections before major festivals such as New Year's Day and Spring Festival every year. In 2007, they also conducted a nationwide survey on food safety hazards.
Various laws and regulations have been formulated one after another, such as People's Republic of China (PRC) Food Hygiene Law, People's Republic of China (PRC) Agricultural Products Quality and Safety Law and Guangdong Edible Agricultural Products Quality and Safety Regulations. It can be seen that China has an iron wrist in rectifying food safety. However, it is puzzling that in recent years, regulatory authorities at all levels have not made great efforts, but inferior foods are still emerging one after another, just like foods containing melamine are constantly exposed, which seriously threatens people's lives and health and makes us feel nervous from time to time.
At present, there are five major problems in the field of food safety in China: food-borne diseases caused by microorganisms, pesticide residues and veterinary drug residues in planting and breeding, weak awareness of law-abiding by producers and operators, food safety problems brought about by the application of new food production technologies, and environmental impact on food safety. These problems have led to the unbalanced development of food production industry in China.
Two major food safety incidents occurred in China, which are still worrying. Once, an epidemic of hepatitis A broke out in Shanghai in early 1988, and people ate the polluted Scapharca subcrenata. At that time, there were 3 10000 patients, which caused many deaths, restricted Shanghai residents' travel (referring to other places), and food exports returned, resulting in heavy economic losses.
The other is the avian flu that occurred in Hong Kong in June, 5438+February, 0997 +65438, which had a great impact on China's poultry export. In recent years, major food safety incidents that endanger people's health and even life have occurred frequently, and their number and degree of harm are on the rise.
For example, 200 1, the case of adding "white sugar" to white sugar in Zhejiang Province; Chongqing "Maofashui" soy sauce case; Cases of inferior rice in Guangdong province; Poisoning of puffer fish in Jiangxi province; Unknown mutton case in Inner Mongolia; Tianjin infusion bottled soy sauce case; Jiangxi province sick and dead pork processed food case; Chongqing illegal processing of fake and shoddy food case; Eating pork containing clenbuterol (clenbuterol hydrochloride) caused more than 60 cases of food poisoning in Hangzhou and more than 0/00 cases in Xinyi County, Guangdong Province. Then today's malachite green, Sudan red, big-headed baby, melamine case and so on. In addition, incidents of food poisoning caused by fake wine, pesticide residues and the addition of prohibited substances in food or feed have occurred from time to time, resulting in deaths and a large number of people being hospitalized collectively.
According to experts' estimation, the total number of people involved in food poisoning reports in China is 20,000-40,000 each year, but this figure is less than one tenth of the actual number, which means that the number of people suffering from food poisoning in China is about 200,000-400,000 each year. Judging from various cases and figures, it is enough to shock us. This time bomb is around us and will explode at any moment.
Therefore, it is urgent to rectify food safety, improve food safety factor and make us eat safely and safely. Third, the main factors that have hidden dangers in food safety After carefully reviewing this series of food problems, it is found that it is not accidental coincidence, but many parties under the current special conditions.
About the composition and epidemic situation of spring, 600 words 20 19 In the days near the Spring Festival, a kind of novel coronavirus suddenly appeared, so everyone had to stay at home and study, relax and have classes online. It turns out that a lively Spring Festival seems so monotonous.
Just wait. Waiting for the early arrival of spring. We can control the virus as soon as possible. At that time, it will be spring flowers, birds singing and flowers fragrant, spring scenery full of gardens, red flowers raining, thousands of trees blooming, grass flying, orchids blooming, willows fluttering and blue waves rippling.
Finally, after countless expectations, we are looking forward to this day. The epidemic situation has been basically controlled by medical experts in China, and spring has come quietly. Grandpa excitedly called and said that the countryside was also unsealed. One sunny day, my father took us to my hometown for a spring outing.
After lunch, I went to look for the footprints of spring. I walked leisurely. I walked to the rape field. Rape has an attractive golden color. Looking from a distance, it is dazzling. Maybe that's the color of spring. Rape also gives off a unique smell. Maybe that's the smell of spring. Hello, spring, I found you in the rape blossoms, and I also found you by the river. Holding hands, my sisters ran and sang, "Where is spring? Where is spring? Spring is in the green forest. " I started jumping when I was walking, and I was very, very happy. Now that spring has really come, it means that the days of fighting the epidemic are coming to an end. Spring is beautiful, but the process of protest is also very difficult.
Don't go out, don't go out to eat, be sure to wear a mask, always open the window for ventilation at home, wash your hands frequently, and eliminate the virus on your hands in snowy days. Don't touch the snow with your hands, because it may carry viruses in the air. Use disinfectant to disinfect after going out.
Now that the epidemic is under control, the unsealing is not relaxed, and zero increase is not zero risk. We can't let our guard down. Come on, we will win the battle.
4. How to write "no return, no matter life or death" in the composition of the novel Coronavirus! "Come as soon as you are called, you can fight when you come, and you can win when you fight"! Obey orders at all times and never back down! Invitations from relevant units and organizations all over the country, like the loudest battle horn, sounded the "epidemic" of novel coronavirus. It was supposed to be a family reunion, but medical workers all over the world, including Wuhan, stopped the epidemic and built a solid Great Wall to protect people's health with their own flesh and blood. Not only medical workers, but also many people from all walks of life: factory workers who work overtime to produce medical masks and protective clothing in short supply, construction workers in volcanic mountains and Thunder God Mountain hospital, railway, police, sanitation, streets, soldiers and so on. Of course, there is no shortage of party member among the "retrograde". "Dear Party Organization, I volunteered to join China * * * ..." On the second day of Wuhan rescue, young nurse Jin Shan submitted an application for joining the Party. Jinshan's mother is a retired soldier. When fighting against SARS in 2003, she fought in the front line as a hospital laboratory doctor. At that time, Jin Shan was a nursing student. "My mother set an example for me, so this time I decided to report to Wuhan. Many excellent medical workers around me are members of * * *, and they are all excellent. I am determined to approach them, give full play to my expertise and win this battle without smoke. " Even retired old party member submitted an application: "Although we are a little older, party member's vanguard and exemplary role has not retreated!" When the motherland and people need him, party member will never be absent. In the face of the epidemic, we saw grass-roots party organizations in hospitals and medical and health units actively directing and dispatching, setting up party member Commando and party member Xianfeng Gang, and organizing the vast number of party member medical staff to charge ahead and fight behind, regarding wards as battlefields, patients as relatives, being fearless in times of crisis, fulfilling their duties, and striving to be "the most beautiful retrograde". Around the epidemic prevention and control work, streets and communities at all levels set up party member responsibility area, party member responsibility post, party member prevention and control vanguard, organized party member cadres to take the lead in full registration and investigation, and publicized and popularized epidemic prevention and control knowledge. "There are no quiet years, but someone carries the burden for you." In the battle to win the epidemic prevention and control, party member people improved their political stance, effectively demonstrated their responsibility, and regarded the epidemic prevention and control as an important test to consolidate and expand the educational achievements of the theme of "Do not forget your initiative mind, remember the mission", which provided a strong guarantee for resolutely curbing the spread of the epidemic. Sacrifice the ego and achieve the big one. Although they walk against the wind, they are born in the sun and shine brilliantly.
5. Write a composition on the topic of "Influenza". What should I do if I have flu-like symptoms? E69DA5E6Ba906216964757A 68696416F3133239306534? What are the symptoms of influenza A h 1n 1?
1。 First of all, if you have a fever, be careful not to blindly take antipyretics. When antipyretics are really needed, they should be taken strictly according to the weight and controlled within a safe dose. Eating too many antipyretics is not good for your health. You should find out where the lesion is, prescribe the right medicine, and radically cure the lesion.
2。 The early symptoms of influenza A (H 1N 1) are similar to those of ordinary people, including fever, cough, sore throat, general pain, headache, chills and fatigue. Some of them may also have diarrhea or vomiting, muscle pain or fatigue, red eye or some of these symptoms. If not treated in time, this disease will lead to pneumonia, respiratory failure and even death.
3。 Note: The body temperature of high fever in the early stage of swine flu is not always higher than 39 immediately, but will gradually increase or appear repeatedly.
4。 Although many people are prone to colds, fever and other physical discomfort when autumn comes and seasons alternate, the early symptoms of influenza A (H 1N 1) are just similar to those of ordinary people, so it is difficult to distinguish them. Since swine influenza A (H 1N 1) is prevalent at present, if its symptoms are similar to some of the early symptoms of influenza A (H 1N 1), for the sake of safety, we should go to the hospital fever clinic or infectious diseases department as soon as possible to carry out influenza A (H1N/).
5。 Note: It is the epidemic period of swine influenza A (H 1N 1). You must wear a mask when you go to a hospital with a high source of infection. You should choose a standard dust mask. A thin ordinary mask can only ensure that the disease will not be transmitted to others, but it can't guarantee that you will be infected by others when you go to the hospital or see a doctor. Feel free! ! ! ! ! !
6。 I suggest that if you have symptoms similar to influenza A (H 1N 1) and feel unwell, go to a public hospital for examination immediately to avoid delaying your illness! Large hospitals are more secure, and being late will affect your health.
I hope my answer is helpful to you.
How to prevent influenza A H 1N 1?
At present, there is no development and production of influenza A preventive drug (H 1N 1) in China. Don't be credulous of the online unofficial propaganda of influenza drugs (H 1N 1).
The best preventive measure is vaccination. I suggest you get the flu vaccine of h 1n 1 early.
1。 All "centers for disease control and prevention" (health and epidemic prevention stations) and public hospitals designated by medical administrative organs can be vaccinated with influenza A vaccine H 1N 1!
2。 The specific details of vaccination can be consulted with the local "CDC" (health and epidemic prevention station) and medical administrative organs.
3。 The telephone numbers of centers for disease control (health and epidemic prevention stations) and medical administrative organs can be found in the "1 14 directory".
4。 Note: It is the epidemic period of swine influenza A (H 1N 1). You must wear a mask when you go to a hospital with a high source of infection. Standard dust masks should be selected. A thin ordinary mask can only ensure that the disease will not be transmitted to others, but it cannot guarantee that you will be infected by others on the way to the hospital and when you are vaccinated with h 1n 1 flu vaccine. Feel free! ! ! ! ! !
I hope my answer is helpful to you.
If someone around you has flu symptoms, you should pay attention to:
1。 Always open the window to keep the indoor air fresh, and go to the drugstore to buy disinfectant (there are a lot of disinfectant used to prevent influenza A (H 1N 1). Thoroughly disinfect the room, especially the door handle, wardrobe door, coffee table and sofa armrest. Tableware and tea meals should also be strictly disinfected and used by special personnel, and the system of separate meals should be advocated.
2。 Maintain good living habits, do a good job in personal hygiene, dry clothes and bedding frequently, wash your hands frequently, and clean and disinfect daily necessities frequently.
3。 When you come into contact with other family members' public goods, you must wash your hands first, and then do other things. Never touch the easily infected parts such as eyes, nose and mouth without washing your hands.
4。 Drinking Radix Isatidis and other heat-clearing and detoxicating series granular tea can play a preventive and health-care role.
5。 Maintain a healthy and good attitude, take an active part in physical exercise, increase resistance and improve your immune function.
I hope my answer is helpful to you.
6. the beginning and end of the composition to prevent diseases are good. The title of the beginning and end of the composition: the beginning of friendship: the friendship of modern people is very strong and fragile.
It is a treasure on the earth, and we need to cherish it. The irreducibility of friendship determines that it is an orphan.
We can have different friendships with different people, but not with the same person. Friendship is a tunnel that is dug deeper and deeper, and there is no turning back. An unforgettable friendship is as unforgettable as hatred.
The end: what remains in the history books is not the interests of haggling over every ounce, but mutual affection. Honest communication with friends can keep us sensitive to our true feelings, erase the dark clouds in our eyes and make our mood happy again. Topic: the beginning and end of unity: a drop of water is insignificant. If it seeps into the soil, it will disappear, but it can converge into a river, but it will never stop flowing.
Just like us, in the face of many difficulties, one person is always weak and powerless, but together, countless miracles can be created. Topic: tolerance begins: tolerance is the supreme virtue in human life.
Because tolerance contains people's mind, because tolerance can transcend everything, because tolerance needs a broad heart. Because tolerance is the most important part of human emotions, which can melt the frost in my heart.
The lack of tolerance will make personality degenerate from greatness to even ordinary. End: Life is often complicated and often dull.
It is precisely because tolerance is like water that complicated things become pure after filtering; It is because tolerance is like fire that insipid becomes more and more distinct through calcination; It is precisely because of this poetic tolerance that life is endowed with art and eternity. Title: the beginning of understanding: understanding is like a cup of tea, which dilutes the misunderstanding between us; Understanding is like spring breeze, which blows away the hard ice that separates the world; Understanding is like a cold plum, which indicates that the warmth of the soul will come to spring; Forgiveness is a rainbow, which makes emotions that have never met shine.
The end: The deceased is like this, and the waves of history have washed away the feud of the dynasty. Today, there are neither overlords nor majestic kings; We pursue unity, enterprising, harmony and equality. We should also keep that quiet and empty, show people understanding with every sentence and expressionless way, and cooperate and communicate with people with understanding.
