Write an epidemic composition of 100 words.

1.2003 infectious disease composition 100 word infectious disease is a terrible word for some people, because it can infect each other through various channels, so people are afraid and stay away from it.

In my opinion, infectious diseases are not terrible, the key is what kind of mentality you use to look at it. Let's say that our most common infectious disease, influenza, has been plaguing people's health since ancient times.

In ancient times, it could threaten people's lives. However, our ancestors did not give in, but tasted all kinds of herbs and finally conquered it with ordinary herbs. Since the invention of chemicals, although it sometimes patronizes our bodies, we are fully capable of subduing it, and it can no longer be violent.

Let's talk about the severe SARS in our country in 2003, because there has never been such a medical history in history, so it is more difficult to treat. However, angels in white, the Chinese nation, was not intimidated, but fought against it with perseverance.

Although no cure for SARS has been found yet, after all, all SARS patients have been discharged from hospital smoothly and returned to work, and SARS has finally been overwhelmed by the spirit of the Chinese nation's unity and never forgetting death. On this day in 2005, "epidemic cerebrospinal meningitis" once again visited our beautiful home.

But can we be conquered by him? Don't! Absolutely not! Although "epidemic cerebrospinal meningitis" has a high mortality rate, it is a loser after all. Humans have formulated a plan to subdue it, as long as we take precautions, actively inject vaccines, achieve early detection, early isolation and early treatment, and face it with an optimistic attitude. I firmly believe: mankind will certainly defeat it! Human science is constantly developing, and no natural or man-made disaster can stop its development.

What's so terrible about just infectious diseases? Let's hold our heads high to meet the new challenges.

2. The composition virus with epidemic situation as the topic can be counted as a certain disease.

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 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. Key words of concern: man and natural environment, environmental protection, human crisis, global problems, public health introspection, biological virus, ecological plunder, man-made conspiracy, life cost. Focus interpretation: human beings are changing the earth, but behind these changes, they have caused benign qualitative changes and 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 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 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.

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 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.

3. What do you want to write in your epidemic diary? What I want to write in the epidemic diary is the ordinary people around me, doing their best to support the fight against the epidemic in their own way.

This epidemic has made each of us more deeply realize that personal protection will not add chaos to the country, nor will it cause trouble to medical staff, but it will contribute to the country.

In the long years of anti-epidemic, the most beautiful figure is the "white retrograde" who fought in the front line. With the handover and use of Vulcan Mountain and Thunder God Mountain hospital, the rescue work is still in full swing. Everyone of us feels that the people of the whole country are United in one place, and we are determined to overcome the difficulties. Although we are far from the front line, we should be grateful and give wisdom.

Believe in our country, the dawn is at hand!

4. What do you want to write in your epidemic diary? What I want to write in the epidemic diary is the ordinary people around me, doing their best to support the fight against the epidemic in their own way.

This epidemic has made each of us more deeply realize that personal protection, not disturbing the country and medical staff, is also contributing to the country. In the long years of anti-epidemic, the most beautiful figure of wisdom is the "white retrograde" who fights in the front line. As Vulcan Mountain and Thunder God Mountain hospital successively handed over the road for use, the rescue work is still in full swing. Every one of us feels that we are back with the people of the whole country, and we are determined to overcome the difficulties. Although we are far from the front line, we should be grateful and give wisdom.

Believe me, in our country, the dawn is just around the corner.

5. About the composition and epidemic situation of spring, 600 words. 20 19 On the day 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.

6. The English composition on disease prevention should prevent I * * * tether tank: out of country's health budget within 100 words. Alargeproportionshould change from treatment to spending on health care and preventive measures. Prevention is better than cure. For the sake of national health budget, a large part should be transferred from treatment to health education and preventive measures.

the risingcostfhealthcare havebeeanissueformonycountries in the world。 In order to solve this problem, people think that part of the national health budget is used for health education and disease prevention rather than treatment. The rising of medical expenses has become a problem in many countries in the world. In order to solve this problem, it is suggested that a large part of the national health budget should be used for health education and disease prevention, rather than for treatment first. Many kinds of disease prevention and treatment are cheap. For example, people can prevent colds. But many people get sick because they have failed and have to give up. But lung cancer, liver cancer and many other kinds of cancer are all possible. Creating more healthy food will enable millions of families to get early cancer prevention measures from banks and patients. First of all, many kinds of diseases are treatments that can prevent and stop diseases and are usually cheaper than them.

For example, people can prevent colds if they wear warm clothes and get a good rest when the weather is cold in winter. But many people get sick because they don't do it, and it will cost more to watch doct 123. Another example is the leading cause of cancer death in the world.

However, if people need to take measures for their health at an early stage, lung cancer, liver cancer and many other types of cancer can be effectively prevented. Small things like smoking or eating unhealthy food will always go bankrupt. If patients take early cancer prevention measures, millions of families will be destroyed.

In addition, health education also plays an important role in promoting people's health. By providing people with healthy information, the state can help people understand the importance of disease prevention. In addition, health education can also play a key role in improving people's health. By providing people with more health information, the state can help people understand the preventive measures of diseases and how to realize their importance.

In a word, we can save money on medical care and treatment. Finally, we can save money on medical care and patient treatment. If our country spends more money on preventive medical care and education, it will be more successful.

7. Composition on Plague and Infectious Diseases 500 words Infectious diseases are the most dangerous diseases in the world, which will cause serious harm and destruction to the human body, so people are more afraid. I'm afraid someone else will catch an infectious disease and infect myself. The most popular infectious diseases are SARS, avian influenza, chickenpox, hand, foot and mouth disease and mumps. ...

So we will take some preventive measures, such as wearing masks, staying away from patients and isolating. But some people are infected because of their physical problems, and no one dares to live with them, which makes them very depressed.

Infectious diseases are pathogens, infectious and epidemic, and often have immunity after infection. Some infectious diseases are seasonal or endemic. The classification of infectious diseases has not been unified. Some people classify by pathogen, others by transmission route. Every infectious disease has its specific pathogen, including virus, rickettsia, bacteria, fungi, spirochetes, protozoa and so on. General infectious diseases enter the human body from the respiratory tract. During the epidemic period of infectious diseases, everyone will go out to wear masks for isolation, or take preventive measures first to avoid being infected.

The primary task of dietotherapy to prevent children's infectious diseases in spring is to do routine prevention work before the epidemic appears. The main contents are as follows:

1. Units that may have pathogens in the external environment shall take measures to improve drinking water conditions and disinfect drinking water; Combined with urban and rural construction, do a good job in harmless manure, sewage discharge and garbage disposal; Establish and improve the rules and regulations of hospitals and pathogenic microorganism laboratories to prevent the spread of pathogenic microorganisms and nosocomial infection; In medical and health institutions, we should also vigorously implement the food hygiene law and carry out disinfection, insecticidal and rodent control work. Although the above work is mainly carried out by health and epidemic prevention and environmental monitoring departments, clinicians should also actively cooperate.

2. Vaccination, also known as artificial immunity, is to inoculate biological products into the human body, causing the body to produce infectious diseases >

8. Help write an introduction about swine flu. H 1n 1 virus h 1n 1 is a virus and belongs to orthomyxoviridae series.

Its hosts are birds and some mammals. All subtypes of H 1N 1 virus have been isolated from wild birds, but the disease is rare.

Some serious diseases caused by H 1N 1 virus mostly occur in birds, but rarely in humans. However, through the spread and variation of birds and mammals, this may lead to the epidemic or large-scale spread of influenza.

The same series as H 1N 1 are H5N 1, H7N2, H 1N7, H7N9, H1N6, H3N8, H9N2, H5N2 and H5N9. Variants sometimes vary depending on the host.

There are mainly the following types: * avian influenza * human influenza * swine influenza * equine influenza * dog influenza is sometimes named according to its fatal birds, especially chickens: * low pathogenic avian influenza (LPAI) * highly pathogenic avian influenza (avian influenza), also known as: the fatal influenza or avian influenza death in H 1N 1 is based on H number (the type of hemagglutinin). Each subtype of avian influenza virus has mutated into various strains with different pathogenic characteristics; Some diseases are caused by one species, but others are unacceptable to many species.

The most famous species has gone extinct. H 1N 1 virus is a single-stranded and segmented RNA virus in the negative sense.

There are 16 different HA antigens (H 1 to H 16) and 9 different applicable antigens (N 1 to N9), which inherit the spherical or filamentous virus structure. Clinical isolation has experienced limited laboratory tests and tissue culture, and filamentous particles are more than spherical particles, but mainly include spherical particles.

The genome of H 1N 1 virus contains eight proteins (ha, na, NP, m 1, m2, ns 1, nep, pa, pb 1, pb), which are encoded by single (unpaired) RNA chains. The total genome size is 13588.

A segmented genome allows the whole gene to coexist in cells with different viral vectors. The part of 8 RNA is: * The infection encoding hemagglutinin is transmitted to the host organism HA.

Influenza virus buds polarize epithelial cells (such as bronchial epithelial cells) from the apical surface to the cavity and lungs, so they are usually pneumophilic. The reason is that the trypsin-like enzyme Kla is limited to the lungs.

However, the subtype H5 and H7 avian influenza viruses in 2004 made the virus grow faster in other organs than in the lungs. *NA neuraminidase.

*NP nuclear protein. *M matrix protein.

* two different nonstructural proteins of ns (NS 1 and NEP). *PA RNA polymerase.

* RNA polymerase of Pb1and protein of PB 1-F2 generation. * PB2 RNA polymerase.

RNA synthesis takes place in the nucleus, while protein synthesis takes place in the cytoplasm. The virus kernel leaves the nucleus and is transplanted to the cell membrane, the transmembrane protein of plaque virus (hemagglutinin, neuraminidase protein and M2) and a basal layer to supply M 1 protein. Through these supplements, the enveloped virus is released into extracellular fluid.

1998 A H3N2 subtype h 1n 1 strain was isolated from North Carolina, USA. The HA, NA and PB 1 genes are human influenza virus genes, the m, NP and NS genes are swine influenza virus genes, and the PB2 and PA genes are avian influenza virus genes [10]. 1H 1N2h 1n 1 which broke out in Japan in 1978 is a new subtype [1 1] produced by recombination of h 1n 1 and H3N2 genes.

H9N2 influenza virus was isolated from Shandong pigs in China, and the analysis may be the result of recombination of chicken and duck influenza virus [10]. After H9N2 subtype influenza virus 1998, it was isolated from pigs for the first time. The results showed that the H9N2 subtype from pigs was highly homologous to the avian influenza virus isolated in China by partial sequence analysis.

Cross-infection and transmission may also occur between SI and human influenza. 1978, H3N2 subtype h 1n 1 was isolated from a pig farm in Taiwan Province province. By sequencing, it was found that the gene fragments of human influenza virus and SI virus were recombined [12].

Due to the great immune pressure of h 1n 1, the amino acid changes of 8 gene fragments have accumulated continuously, and their antigens have obvious variation. In the isolated geographical environment, h 1n 1 can persist and maintain relative genetic stability [13- 14].

As a "mixer" of influenza virus, pigs play an important role in the process of influenza virus crossing the species barrier and infecting new hosts. Because there are sialic acid 2,6-galactoside and sialic acid 2,3-galactoside in pig epithelial cells, human influenza virus can bind to the former, and avian influenza virus can bind to the latter, so pig epithelial cells can be infected by human influenza virus and avian influenza virus and become a living vector for gene recombination between strains [15- 16].

Because h 1n 1 can directly infect people, resulting in human illness or death, its public health significance is increasingly significant. Strengthening the research on h 1n 1 is of far-reaching significance for reducing the world economic losses and improving human health.

[Edit this paragraph] Specific introduction of the epidemic situation H is called hemagglutinin and N is called neuraminidase. They are all glycoproteins, which are distributed on the surface of the virus. H has subtype 1- 15, and n has subtype 1-9 (take virus A as an example).

Because of the different combinations of H and N, the toxicity and transmission speed of the virus are also different. 19 18~ 1920 first appeared in the eastern United States in 19 18, and it was popular in the French army in April of 19 18, and then spread rapidly.

This epidemic is called the biggest plague in human history, and the total death toll is estimated to be about 20 million. As for the pathogen of this epidemic, according to serological tracing, it is believed that it is caused by swine influenza virus HSW1N1(H1N1).

On April 25th, 2009, there was a sudden outbreak of swine flu in Mexico. US officials said on the 28th that they are considering changing the name of the current rampant influenza epidemic, because "swine flu" will lead people to misunderstand that the epidemics in Mexico, the United States and other countries are related to eating pork.

The Associated Press reported that the virus was actually a mixture, which concentrated the characteristics of swine flu virus, human influenza virus and avian influenza virus. Because American officials believe that although the swine flu virus has played a certain role in it, it is not accurate to simply name the current flu as "swine flu", but it has seriously affected the export of pork and pork products in North America.

The US Centers for Disease Control and Prevention said that eating pork will not cause swine flu, and the virus may spread from person to person at present. American disease control and prevention.

9. Who can help me write a 300-word composition with the topic of preventing influenza? It is an acute respiratory infectious disease caused by influenza virus, and the pathogens are influenza viruses A, B and C ... especially type A is more common. It happens in winter and spring. The common cold, which can be called upper respiratory tract infection (commonly known as cold), is one of the most common diseases.

Influenza viruses are usually spread by droplets produced by sneezing or coughing. After people get the flu, the symptoms will suddenly appear and get worse within a few hours, and the high fever will not go away, and the body temperature can reach above 39℃. Eye swelling and pain, limb pain, fatigue, sometimes conjunctival congestion, nasal congestion, runny nose, dry throat. Children often have gastrointestinal symptoms such as abdominal pain, abdominal distension, diarrhea, vomiting and even convulsions. Influenza symptoms are more threatening to infants, the elderly and patients with chronic diseases.

Western preventive medicine

Compound cold medicine containing antiviral components can relieve flu symptoms, shorten the onset time and reduce the severity of the disease. Preventive medication can reduce the incidence of influenza during the influenza epidemic.

◆ Amantadine hydrochloride and rimantadine hydrochloride can prevent influenza A ... it can block the infection of virus to human body. Amantadine hydrochloride can reduce the severity and incidence of symptoms caused by influenza by 70%-90%. The preventive effect on influenza A is equivalent to that of vaccine. Researchers have confirmed that taking it for 3 to 5 days can prevent influenza A during the influenza epidemic. If you are pregnant, baby, mentally ill or epileptic, please consult a doctor before use.

◆ Ribavirin, also known as ribavirin, has been proved to be resistant to both influenza A and influenza B in vitro, but its clinical efficacy has not been affirmed. Recently, a class of neuraminidase inhibitors, such as 4- guanidine N- acetylneuraminic acid, have been developed internationally, which can resist both influenza A and influenza B, and are currently in the clinical application stage.

◆ Injecting influenza vaccine can prevent influenza to a certain extent, but it can't cover all virus strains, which affects the prevention effect. If you are pregnant or allergic to eggs, please consult a professional doctor if it is suitable for influenza vaccination.

Traditional Chinese medicine prevention

Here are some commonly used prescriptions for your reference:

◆ Folium Artemisiae Argyi 15g, Rhizoma Atractylodis 65438g, Realgar 65438g, once a day 1 time, 3-5 times in a row, and disinfect the room.

◆ Take 30 grams of wild chrysanthemum, decoct in water, take it or spray it on the throat.

◆ Take 30g of Folium Isatidis, 30g of Radix Isatidis and 30g of Rhizoma Chuanxiong, and decoct them in water, daily 1 dose.
