Descriptive composition of infectious diseases

1. Write a short article about the understanding and prevention of infectious diseases in spring. In spring, cold and warm air meet, and the weather is changeable, cold and hot, which is suitable for the breeding of many pathogenic microorganisms.

Respiratory resistance decreased, and more people went out for sightseeing. If you don't pay attention to maintenance, it's easy to get infectious diseases. Every spring, the clinics of respiratory and intestinal infectious diseases in major hospitals are often overcrowded, so some people call spring "the spring of many diseases".

Infectious disease experts remind people that spring is the frequent season of various infectious diseases, so we should strengthen our awareness of self-prevention, neither blindly panic nor treat it lightly, and pay attention to taking active preventive and comprehensive control measures to prevent pathogens from leaving the body. Infectious diseases can spread from person to person, and there must be three basic links: the source of infection, the route of transmission and the susceptible population. Without any link, infectious diseases cannot spread.

Taking influenza as an example, this paper explains three basic links in the epidemic of infectious diseases. When people with influenza talk, cough or sneeze, they will spray a large number of droplets containing influenza virus from the nasopharynx and suspend them in the air. When people around you inhale the air with the virus, the virus will enter the respiratory tract, which may cause the flu.

It can be seen that the source of influenza infection is mainly influenza patients, and the transmission route is droplet transmission and air transmission, and the susceptible population can include most people. Measures to prevent infectious diseases 1. General measures: When infectious diseases are prevalent, cutting off any one of the three basic links can stop the epidemic of infectious diseases.

⑴ Control the source of infection: Many infectious diseases are infectious before the onset, and the most infectious diseases are when they show infectious symptoms at the initial stage. Therefore, early detection, early diagnosis, early reporting, early treatment and early isolation should be done as much as possible to prevent the spread of infectious diseases.

Animals suffering from infectious diseases are also sources of infection and should be dealt with in time. This is an important measure to prevent infectious diseases.

⑵ Cut off the route of transmission: The main way to cut off the route of transmission is to pay attention to personal hygiene and environmental hygiene. Eliminating the vectors that spread diseases and carrying out some necessary disinfection work can make pathogens lose the opportunity to infect healthy people.

⑶ Protection of susceptible population: During the epidemic period of infectious diseases, attention should be paid to protecting the susceptible population, keeping it away from the source of infection, and carrying out vaccination to improve the resistance of the susceptible population. Carrying out patriotic health campaigns to eliminate flies, mosquitoes, rats, bedbugs and other animals that spread diseases or diseases can play a great role in controlling the epidemic of infectious diseases.

2. Specific measures: (1) Eat a reasonable diet, increase nutrition, drink more water, take enough vitamins, and eat more foods rich in high-quality protein, sugar and trace elements, such as lean meat, eggs, jujube, honey, fresh vegetables and fruits. (2) Take an active part in physical exercise, go to the suburbs and outdoors to breathe fresh air, take a walk, jog, do exercises, punch, etc. Do this every day to make your blood flow smoothly, stretch your bones and muscles, and strengthen your physique.

(3) Don't go to places with dense population, mixed personnel and air pollution for leisure. (4) Wash your hands with running water, and don't use dirty towels.

5] Open the window for ventilation every day to keep the indoor air fresh, especially in dormitories, computer rooms and classrooms. [6] Reasonably arrange rest and make life regular; Be careful not to be overtired to prevent colds, so as not to reduce the disease resistance.

Once you don't eat, don't process unclean food, refuse to eat all kinds of seafood and meat raw, don't eat fruits with skins, and don't drink raw water. Being don't literally take out the garbage, don't literally pile up garbage; Don't spit or sneeze casually.

Pet-name ruby fever or other unwell symptoms in a timely manner; It is best to wear a mask when going to the hospital and wash your hands after returning to the dormitory to avoid cross infection. Although there are many kinds of infectious diseases in spring, as long as we pay attention to prevention, we can effectively block the epidemic and spread of infectious diseases.

2. 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 >

3. About cultivating health habits, stay away from infectious diseases, 300-500 words to cultivate health habits, stay away from infectious diseases.

With the rising sun in Ran Ran, we go to school to study for our tomorrow. Tomorrow will present gorgeous colors, realize our dreams and create our miracle tomorrow. Tomorrow is so beautiful, so what should we do today to make it really beautiful? I think we must form good behavior habits and prepare for tomorrow. However, in the activity class, some students' language is uncivilized, some students talk dirty, and fighting and swearing sometimes occur. So, what should we do? We should do the following:

1, start from me, start from now on, develop good behavior habits, and don't call names.

2. Take care of public facilities, do not scribble, do not trample on the lawn, and do not climb branches.

3. Say goodbye to uncivilized behavior consciously and fight against uncivilized behavior.

Students, when we sow an action, we will gain a habit; Sow a habit and you will reap a character. Let's sow the seeds of good behavior habits and let them sprout and grow. One day, we will reap sweet fruits, and then we will certainly create a beautiful "tomorrow"!

4.2003 infectious disease composition 100 words. For some people, infectious disease is a terrible word. Because it can infect each other through various channels, 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 "SARS" that was fierce in China in 2003. Because there has never been such a medical history in history, it is more difficult to treat it. 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.

5. Composition describing diseases that are easy to get in winter. Winter is the season of high incidence of some infectious diseases. Knowing and mastering some basic preventive knowledge can help us stay away from diseases and enjoy a happy life and study.

Today, the school used this time to introduce some common infectious diseases popular in winter to the students. Common infectious diseases in winter mainly include the following: influenza, measles, mumps, chicken pox and so on. , and the newly discovered SARS in recent one or two years, H 1N 1.

Let's learn about these infectious diseases first. Influenza is an acute respiratory infectious disease caused by influenza virus. The pathogens are A, B and C, and the disease is spread by droplets.

Highly contagious, it is easy to cause explosive epidemic or worldwide epidemic. It is characterized by high fever, headache, fatigue and muscle soreness. Symptoms of systemic poisoning are obvious and respiratory symptoms are mild.

When the flu epidemic is discovered, we should reduce the number of meetings, pay attention to the ventilation of the house and prevent influenza vaccination. The patient was isolated at home until 5~7 days after illness or 2 days after fever.

Mumps, also known as mumps, is an acute respiratory infectious disease caused by mumps virus. It is mainly spread by droplets.

The virus invades the human body from the respiratory tract, causing parotid gland or submandibular gland enlargement. It is often popular in kindergartens and primary schools.

Children under 2 years old are less likely to get sick. Usually only once in a lifetime.

It is generally believed that the isolation period should be from the onset of parotid gland enlargement to its complete disappearance, about 3 weeks. Chickenpox is an acute infectious disease caused by varicella-zoster virus, which mainly occurs in children.

It is characterized by scattered spots, papules and herpes zoster on the whole body skin in batches, accompanied by fever. Generally, herpes zoster will heal after scabbing, leaving fewer scars.

Chickenpox is highly contagious, so children must be isolated as soon as possible until the isolation period expires. Protection of susceptible population: live attenuated varicella vaccine can be used for emergency vaccination, and vaccination within 3 days after contact can be protected, and vaccination within 5 days after contact can prevent varicella from spreading in the ward.

Chickenpox vaccine can be used in all susceptible people and is the most effective measure for chickenpox. In addition, the appliances of children with chickenpox should be exposed to the sun or boiled for disinfection.

Measles is an acute respiratory infectious disease caused by measles virus. The source of infection is measles patients, mainly through droplets or direct contact with nasal and laryngeal secretions of patients.

The incubation period is usually 14 days. Cough, runny nose, fever, jealousy and oral leukoplakia (Koch's leukoplakia) appeared in the early stage of infection; After 3 ~ 7 days, maculopapules will appear on the skin, which generally spread from the face to the whole body for 4 ~ 7 days, and brown spots or desquamation will appear. In severe cases, pneumonia, myocarditis and encephalitis may occur.

The patient was isolated until 5 days after the rash subsided or broke out. In addition, rubella, scarlet fever and meningitis are also common infectious diseases in schools.

What should we do when these infectious diseases appear around us? First of all, the most effective way is to purify the indoor environment, maintain moderate ventilation, maintain air circulation, and let sunlight enter the room. Students should always remember to open the window to ventilate the classroom and go outside to breathe fresh air during recess.

Secondly, to ensure adequate sleep, primary school students should ensure ten hours of sleep every day, drink more water, ensure diet nutrition, eat more green vegetables, properly supplement vitamin intake, and never be partial to food or picky eaters. Moderate exercise can enhance physical fitness.

Physical exercise can accelerate human blood circulation and metabolism, enhance adaptability to climate and environment, and is very important for improving human immunity and disease resistance. Remind everyone to avoid sweating a lot when exercising at school, and don't take off your coat at will.

Third, pay attention to personal hygiene and personal protection. Cultivate the good habit of frequently cutting nails and washing hands, and try not to go to supermarkets, banquets and other public places where people are concentrated.

Cover your nose and mouth with a tissue when coughing or sneezing, and then throw the tissue into the trash can. At the same time, corresponding vaccination can be carried out, such as influenza, pneumonia, measles, mumps and other vaccines.

Fourth, early detection, early reporting and early treatment are required. If you are sick, you should go to the hospital in time, treat actively, avoid taking medicine indiscriminately or delaying your illness due to negligence, report to the teacher in time, and stay at home to rest, reduce contact with * people and avoid infecting others.

Fifth, increase * * * health education, educate students to develop good health habits and improve self-protection awareness. Sixth, the school implements the morning check-up system, so as to find patients early and take measures.

Seventh, carry out targeted vaccination. In addition, when the weather turns cold, people's appetite begins to recover, and many people don't pay as much attention when eating as in summer.

Autumn and winter are still the seasons with frequent food-borne diseases. At this time, it is more important to pay more attention to all aspects of food hygiene from the mouth to prevent problems before they happen. Finally, keep an optimistic mood and don't be overly nervous.

Infectious diseases can be prevented and cured in winter, and the key is scientific treatment. I wish the students good health, happiness every day and academic progress.

6. You can only find some information for reference in the composition about spring disease prevention, and you can't copy it, so you can write and ask questions yourself and prevent diseases yourself. Seven methods of diet conditioning in spring It is early spring, and the temperature is still relatively cold. Moreover, the temperature has changed greatly recently, and it has started to turn from cold to warm.

During this period, scientific diet aftercare is very helpful to keep healthy and prevent diseases. In spring, people tend to get angry, with yellow tongue coating, bitter taste and dry throat, so the diet should be light and avoid greasy, cold and * * * food.

People with obvious symptoms of excessive internal heat can eat some foods that can clear the fire, such as mung bean soup, honeysuckle tea, chrysanthemum tea and lotus plumule soaked in water. Slightly spicy things, such as onions, ginger, leeks, garlic sprouts and so on. Are all foods that nourish spring.

There is a saying in the Tang Dynasty Fang that "it is easy to eat leeks in February and March". Eating these foods in spring is good for human yang.

Chinese medicine believes that the liver, one of the five internal organs of the human body, should eat food with stimulating temperature rise in season, while cold and sticky food should be eaten less to avoid hurting the spleen and stomach. Therefore, it is advisable to eat more sweets and less sour food in spring. "Spring Sleepiness" makes people tired and depressed. Eat more red, yellow and dark green vegetables, such as carrots, pumpkins, tomatoes, green peppers, celery, etc., which is very beneficial to restore energy and eliminate spring sleep.

After the temperature rises gradually in spring, bacteria, viruses and other microorganisms also begin to multiply in large numbers, and their vitality is enhanced, which is easy to invade the human body and cause diseases. Therefore, you should take enough vitamins and minerals in your diet.

Fresh vegetables such as cabbage, kale and broccoli, and fruits such as citrus and lemon are rich in vitamin C and have antiviral effects. Yellow-green vegetables such as carrots and spinach are rich in vitamin A, which can protect and strengthen epithelial cells of upper respiratory mucosa and respiratory organs, thus resisting various pathogenic factors. Diseases such as gastric ulcer and duodenal ulcer are prone to occur in spring. In diet, we should avoid taking broth, chicken soup, fish soup, animal offal and * * condiments rich in creatine, purine base and other substances, because these foods have strong * * * gastric juice secretion function or form gas to produce abdominal distension, which increases the gastrointestinal burden.

Chronic bronchitis and bronchitis are also easy to attack in spring. It is advisable to eat more foods with expectorant, spleen-invigorating, kidney-tonifying and lung-nourishing functions, such as loquat, orange, pear, walnut and honey, which will help relieve symptoms. It's another spring, full of flowers and sunshine, and there is a thriving scene everywhere.

However, every spring is the season when diseases are easy to occur and spread. In the season of "blowing my face without cold willows", I occasionally have a physical fatigue, headache and brain fever.

Outpatients in major hospitals are often overcrowded, and rhinitis, flu, pneumonia, measles and mental illness come at once, so some people call spring "the spring of many diseases". Medical experts point out that spring is a period when cold and warm air meet frequently, and the weather is changeable, cold and hot. If you don't pay attention to health, it is easy to get epidemic diseases.

Busy people should pay close attention to their health while planning their work for a year. There are many diseases and viruses in upper respiratory tract infection, and there are also many opportunities for infection.

Respiratory tract infections occur all year round, but spring is the season with the most upper respiratory tract infections. Upper respiratory tract infection, commonly known as "cold", the common cold is more acute, and the early symptoms include dry throat, itching or burning sensation, sneezing and stuffy nose.

Seasonal reasons: in sunny seasons, group activities will increase, the chances of cross-infection will increase, and there are bad living environments, such as unqualified indoor decoration. Self-prevention: ① Eat more fruits: Eat more dark fruits, such as pears, sugar cane, radishes, strawberries, purple grapes, etc. These fruits are rich in antioxidants, which can fight against free radicals that cause immune cell damage and immune function decline.

② Vitamin C and vitamin E supplementation: It has anti-infective effect and can relieve respiratory congestion and edema. ③ Physical exercise: Moderate exercise can increase the interleukin in the blood, thus enhancing the activity of immune cells, eliminating pathogens and improving human immunity.

(4) Adequate sleep: When people sleep, other organs of the body are dormant, while the immune system is active, white blood cells increase, and liver function is enhanced, thus eliminating bacteria and viruses that invade the body. Allergic dermatitis Spring is a difficult season for people with sensitive physique, and troubles may appear on the skin, especially on the face.

The wind is strong in spring, and there are a lot of floating dust, flying catkins, pollen and other factors that can easily cause allergies, which can easily cause skin allergies. Many people also feel dry skin. After using skin care products, the skin will be dry, red and swollen.

Seasonal reasons: due to the gradual improvement of human metabolic capacity in spring, sebaceous gland secretion increases, and the skin itself is also changing. During this period, the skin is very sensitive. If you don't pay attention to protection and maintenance, you will suffer from dermatitis, and women's skin is more susceptible to allergies.

There are many reasons for allergies, among which the most common reasons are food, animal fur, mites, insects, a large number of floating pollen in the air, dust, air pollution, pesticides, fertilizers, detergents, rubber shoes, chemical fiber raw materials and little-known fungal allergies. Moreover, seasonal changes make the cells related to allergies in the body unstable, and allergic symptoms also appear accordingly.

Self-prevention: ① Steam your face: pour boiling water into a big bowl and put your face on it for about 15 minutes, or even simpler. Cover your face with a hot towel or take a long hot bath, which is helpful to treat allergic dermatitis. 2 Use yogurt as a mask: Yogurt contains a lot of lactic acid, which can play the role of exfoliating mask. Mild effect, not * * * skin. Daily use will make the skin soft and delicate.

3 antipruritic: drinking rock sugar tremella soup has a good nourishing effect on the skin. ④ Strengthen skin care and stay away from allergens, especially those with allergies.

⑤ Limit the lipopolysaccharide diet, avoid drinking and eat more fruits and vegetables. Skin diseases In spring, the number of patients with various skin diseases increased significantly.

Like viral skin diseases, mainly chicken pox, rubella and so on; Recurrent facial dermatitis, commonly known as spring dermatitis, is more common in women aged 18~40, mainly manifested as desquamation, itching, dryness and other symptoms, and some manifested as erythema, papules and scales, which were relieved after one week. There are also some women who show increased freckles or brown spots.

In addition, there are many papular urticaria caused by mosquito bites and dermatitis caused by contact or inhalation allergies.

7. Prevention of infectious diseases in autumn Generally speaking, common infectious diseases in autumn can be divided into three categories: intestinal infectious diseases, respiratory infectious diseases and insect-borne infectious diseases.

Common intestinal infectious diseases include cholera, typhoid fever and dysentery. This infectious disease is spread through the "feces-mouth" route, and it is an infectious disease that is "eaten". It is usually caused by bacteria or viruses contaminating hands, drinking water, tableware or food. And if you don't treat it properly, you will get sick after eating it.

Common respiratory infectious diseases include influenza, legionnaires' disease and tuberculosis. This infectious disease spreads through the respiratory tract and is an "inhaled" infectious disease.

Bacteria and viruses spread through the air or enter the human body through the respiratory tract through bacteria or virus droplets in dust. Common insect-borne infectious diseases include Japanese encephalitis, malaria, dengue fever and epidemic hemorrhagic fever.

This infectious disease is spread by some insect vectors, such as mosquitoes, mites, lice and fleas. This is an infectious disease spread by bites. Insects bite patients first, then healthy people, and at the same time introduce bacteria or viruses into healthy people to cause disease.

8. The 800-word composition on AIDS prevention was forgotten. From that day on, AIDS, a word with a slight western color, came into our lives. It woke us up in our sleep, let us know about AIDS, understand AIDS, fear AIDS and stay away from AIDS patients.

At this time, human nature will be shown. I am not familiar with Pu Cunxin, but he is a famous AIDS ambassador. Maybe I can't even write his name, but I admire him from the bottom of my heart because he has a clear heart and a noble soul. In fact, I know in my heart that AIDS is transmitted through sex, blood and mother to child. But even if human nature is selfish, I will protect myself. If someone stands in front of me and says he wants to. Firmly shake hands with them, eat and communicate. Maybe these are too insignificant among normal people. But if it is between a normal person and an AIDS patient, it is a noble integrity. How wonderful. They did it, but I really can't do it today.

At the beginning of life, human nature is good. Maybe selfishness killed my kindness. Also, today I can only sing a triumphant song here, praising those who can achieve equality with AIDS patients in all aspects. Sorry, I still can't do it today ~

Aware cat can test itself at home without drawing blood, which is simple and convenient.

AIDS is a serious infectious disease. Together with HIV, it invades the human body, destroys the immune function of the human body, causes many incurable infections and tumors in the human body, and finally leads to the death of the infected person.

Global AIDS has caused 28 million deaths in the past 20 years, and there are still 43 million patients, with 6.5438+0.4 million new patients every day. There are 650,000 people infected with AIDS in China, with an increase of 192 every day last year.

There are three main ways to spread AIDS: first, sexual contact; The second is blood transmission; The third is mother-to-child transmission.

At present, AIDS is still an incurable disease. It threatens everyone and every family, and it is the responsibility of the whole society to prevent AIDS. ]

1, lead an honest and clean life. Abiding by sexual morality is the fundamental measure to prevent sexually transmitted diseases and AIDS. 2. Use condoms. Proper use of condoms can not only prevent pregnancy, but also reduce the risk of contracting AIDS and sexually transmitted diseases. 3, the treatment of sexually transmitted diseases. Early treatment and cure of sexually transmitted diseases can reduce the infection of AIDS. Regular hospitals can provide regular and confidential examination, diagnosis, treatment and service consultation, and if necessary, they can consult the local STD and AIDS service hotline. 4. Stay away from drugs. Avoid sharing needles, prohibit drug use and reduce blood contact. When dealing with wounds, we must pay attention to avoid skin, eyes and mouth coming into contact with other people's blood. 5. Prevent cross infection. Avoid unnecessary blood transfusion, injection, unsafe tooth extraction and beauty without strict disinfection, and use blood and blood products tested by HIV antibody.

As long as you follow the method of preventing AIDS, you won't be infected with this disease. You can stop wasting your life.

9. Small animals can get infectious diseases. My dog.

My family has a lively puppy. It has snow-white fur, and only its forehead is light brown. It has a sharp and long mouth, sharp teeth and claws, a red and wet nose, triangular ears and bright big eyes, just like a snow white. It is very beautiful. I gave the dog a name, Huanhuan.

Huanhuan's personality is the same as the name, very cheerful and lively. Whenever I come home from school, Huanhuan will suddenly rush out, wander back and forth between my feet, and even jump on me and ask me for a hug. After that, my mother found a small table we didn't need, put Huanhuan on it, and it was almost time for school. Huanhuan sat on the table and looked up at the school gate. Those melancholy eyes seemed to say, "Little master, when will you finish your studies?" I'll wait at home for you to come back and play with me! "After school, the students lined up and walked out of the school gate. Huanhuan looked at them one by one, as if looking for my little master. When it saw me, Huanhuan could only wag its tail, and its four little feet kept stomping around, very excited, as if to say, "Little master, you have finally come back, I have been waiting for you for a long time! "It's a pity that it is on the table and can't come to play with me.

Now, Huanhuan has grown up and is more lively than before. Every time I sweep the floor with a broom or mop, I will pounce on her, hug her and throw my head around so that we can't pull it out. A broom was bitten by a puppy before. Now we hold the broom high. The puppy saw it and wanted to jump up and bite. We were all stunned when he jumped down. I didn't expect the puppy to jump so high. It's really amazing. What else! Dad hung a cotton rope on the wall. The puppy saw it, jumped lightly, took a bite and kept pulling down. The cotton rope went up and down for a while. Very interesting!
