High school health education teaching plan

The following is a selection of high school health education teaching plans that I have compiled for you. Welcome to read, for reference only, I hope it will help you. More articles are in the lesson plan column, I hope everyone will pay attention and read.

High school health education teaching plan chooses a course topic: understanding type A H 1N 1 stream.

1. What is influenza A H 1N 1?

Influenza A H 1N 1 is a highly contagious acute respiratory disease in pigs, which is caused by one of several swine influenza A viruses. High morbidity and low mortality (1%-4%). The virus spreads in pigs through aerosol, direct and indirect contact, and asymptomatic pigs carrying the virus can also spread. In temperate regions, the prevalence of pigs may occur all year round, but it is more frequent in autumn and winter. Many countries routinely vaccinate pigs against influenza A (H 1N 1).

Influenza A virus H 1N 1 is the most common subtype H 1N 1, but there are other subtypes (such as H 1N2, H3N 1, H3N2). Like influenza A virus H 1N 1, pigs can also be infected with avian influenza virus and human seasonal influenza virus. At first, it was thought that influenza virus H3N2 A H 1N 1 was transmitted from human to pigs. Sometimes, pigs can be infected with more than one virus type at the same time, so that the genes of these viruses can be recombined or rearranged. This may lead to influenza virus containing genes from many sources, called recombinant virus. Generally speaking, influenza A virus H 1N 1 has species specificity, only infects pigs, but sometimes it can cross the human barrier and cause human diseases.

Second, what is the impact on human health?

Occasionally, sporadic cases and outbreaks of human infection with influenza A virus H 1N 1 were reported. Generally speaking, the clinical manifestations of influenza A virus (H 1N 1) infection are similar to seasonal influenza. However, according to the reported cases, its clinical manifestations vary from asymptomatic infection to severe pneumonia that leads to death.

Because the clinical symptoms of typical human infected with influenza A virus H 1N 1 are similar to seasonal influenza and other acute upper respiratory infection diseases, most cases can sometimes be found through seasonal influenza surveillance. However, mild cases and asymptomatic infections may be difficult to find, so the real situation of human infection with the disease is still unclear.

Third, how are people infected?

Humans are usually infected with influenza A virus H 1N 1 from infected pigs. However, some cases have no contact with pigs or have never been in contact with the environment where pigs are located. In some cases, human-to-human transmission has occurred, but it is still limited to close contacts and people in a closed environment with patients.

4. Is it safe to eat pork and pork products?

Very safe. Eating properly treated and thoroughly cooked pork and other pork products will not cause infection. Influenza A virus H 1N 1 is killed when it is heated to 70℃/160℃, and the cooking temperature of pork and its meat can generally reach this temperature.

5. What is the risk of the epidemic?

Most people, especially those who have no daily contact with pigs, lack immunity to influenza A virus H 1N 1. If influenza A virus H 1N 1 has effective interpersonal communication ability, it may cause an influenza epidemic. Once this kind of virus causes an epidemic, its influence degree is difficult to predict: it depends on the virulence of the virus, the immune level of the population, the cross-protection effect of antibodies obtained from seasonal influenza virus infection and the individual factors of the host. Influenza A virus H 1N 1 can be recombined with human influenza virus to form hybrid virus, which may cause epidemic situation.

6. Is there a human vaccine to prevent influenza A (H 1N 1)?

Not yet, but related vaccine research and development is under way. When an influenza virus is prevalent, the influenza vaccine against this virus usually contains the influenza virus that has been killed (that is, inactivated) or reduced in toxicity, so that antibodies against this virus can be produced in the human body, thus preparing the immune system for the real influenza virus.

In order to achieve the best prevention and protection effect, the virus contained in the vaccine must be as close as possible to the epidemic virus. The influenza A virus H 1N 1 is a new virus, and no influenza vaccine containing this new virus has been made yet. It usually takes five to six months to develop a brand-new influenza vaccine.

7. How important is the vaccine to control the influenza epidemic?

When influenza is prevalent, vaccine is one of the most valuable protection means. Other prevention and control methods include using antiviral drugs, controlling public social activities and maintaining personal hygiene.

8. Can the existing vaccines against seasonal influenza resist influenza A H 1N 1?

In view of this problem, the existing scientific evidence is not sufficient, but preliminary research shows that seasonal influenza vaccine has little or no protective effect on people when dealing with influenza A (H 1N 1).

9. Is there any medication?

In some countries, drugs against seasonal influenza virus are available, and the prevention and treatment of the disease are effective. There are two kinds of drugs: 1) alkylamines (amantadine and rimantadine); 2) Influenza virus neuraminidase inhibitors (oseltamivir and zanamivir).

Most previously reported cases of influenza A (H 1N 1) were cured without medication and antiviral drugs.

Some influenza viruses have developed resistance to antiviral drugs, which limits the effectiveness of chemopreventive drugs and therapeutic drugs. Recently, influenza A virus infected with H 1N 1 in the United States was sensitive to oseltamivir and zanamivir, but resistant to amantadine and rimantadine.

X. how to prevent daily life?

1, avoid contact with patients with flu-like symptoms (fever, cough, runny nose, etc.). ) or respiratory diseases such as pneumonia.

2, pay attention to personal hygiene, indoor ventilation, often wash your hands with soap and tap water, especially after coughing and sneezing.

3. Avoid touching live pigs or going to places with live pigs.

4. Avoid going to crowded places.

5. Cover your nose and mouth with a tissue when coughing and sneezing, and then throw the tissue into the trash can.

6. Eat properly cooked pork and pork products; When cooking pork, the internal temperature of pork is 7 1? C, can kill bacteria and viruses.

7. If you have flu-like symptoms (fever, cough, runny nose, etc. ), you should see a doctor immediately (you should wear a mask when you see a doctor).

Specific requirements for students: 1. Understand what influenza A (H 1N 1) is, the impact of influenza A (H 1N 1) on human health, and the ways of human infection with influenza A (H 1N 1). 2, pay attention to personal hygiene, indoor ventilation, often wash your hands with soap and tap water, especially after coughing and sneezing. 3. Avoid going to crowded places. 4. Cover your nose and mouth with paper towels when coughing and sneezing, and then throw the paper towels into the trash can. 5. If you have flu-like symptoms (fever, cough, runny nose, etc. ), you should see a doctor immediately (wear a mask when seeing a doctor) and report to the teacher immediately.

Homework: self-examination. Is your dormitory often ventilated? Do you use soap and running water when washing your hands?

Selected teaching plans for health education in senior high school II Course assignment: To prevent trachoma, we should develop good living habits.

Teaching purpose: 1. Know what trachoma is. 2. Understand the harm of trachoma. 3, master the prevention method of trachoma-develop good living habits.

Teaching emphasis: master the prevention method of trachoma-develop good living habits.

Teaching content:

It is generally believed that trachoma, as its name implies, is caused by sand blowing into the eyes. Actually trachoma is a chronic infectious disease of conjunctiva and cornea caused by chlamydia infection. Trachoma can be spread through towels and washbasins used by * *.

Trachoma can make us feel itchy, dry and burning, just like sand entering our eyes. When the doctor examines our eyes, he will see that the conjunctiva of the upper eyelid is covered with small hair follicles like small grains of sand, hence the name "trachoma". They rub the cornea of the eye, so we feel itchy and even painful. After trachoma infects conjunctiva, the incubation period is about 5- 12 days, which mostly occurs in children and adolescents. There was no discomfort in the early stage of the patient, which was only discovered during the physical examination. After the development of the disease, most of them have symptoms such as tears, photophobia, itching, foreign body sensation, burning sensation and dryness.

First, the harm of trachoma

Trachoma is the second leading cause of blindness in the world after cataract. The cause of blindness caused by trachoma is the damage to cornea caused by trachoma. If trachoma is not treated in time, the corneal surface will become rough, smooth and transparent like glass due to friction, and the transparent cornea will become turbid, and the transmittance will decrease, eventually leading to blindness.

A doctor of the World Health Organization (WHO) pointed out that China has the largest number of blind people in the world, with about 5 million people, accounting for 18% of the total number of blind people in the world. About 450,000 people are blind in China every year. If the current trend continues, it is predicted that the number of blind people in China will increase fourfold by 2020, and more than 10% of them will be blind due to trachoma.

Second, how to prevent trachoma?

Trachoma is easily transmitted from one person to another in many different ways. People with trachoma often have jealous, sticky secretions and sometimes a runny nose. Viscous secretions can easily spread to objects such as fingers, clothes, towels and washing utensils. Close contact between people, trachoma will spread. It can be seen that the spread of trachoma is closely related to the health habits, living conditions, living environment, nutritional status, medical conditions and other factors of patients. Of course, trachoma is not necessarily blind. If trachoma has been infected, treatment is very important, which can prevent it at every stage, block its development and keep people away from the harm of blindness.

To prevent trachoma, we must first develop good hygiene habits. Don't rub your eyes with dirty hands, don't use washbasins and towels with others, and so on. This can reduce the chance of trachoma infection. If you feel uncomfortable with your eyes and have symptoms such as itchy eyes, redness and tears, you should go to the hospital for examination in time. If there is trachoma, it can be treated with eye drops; In acute phase or severe infection, oral medication or infusion is needed. It's spring, windy and dry air, which is very conducive to the spread of diseases, and it's also a period of frequent trachoma, so we must pay attention to eye hygiene.

Specific requirements for students: 1. Know what trachoma is. 2. Understand the harm of trachoma. 3, standardize their living habits, form good habits, such as don't rub your eyes with dirty hands, don't use washbasins and towels with others.

Homework: How are you going to prevent trachoma? Please talk to each other.

Selected teaching plans for senior high school health education: prevention of myopia lecture.

Teaching purpose: 1. Know what myopia is. 2. Understand the basic knowledge of preventing myopia. 3. Establish the awareness of liking and protecting eyes, and develop good eye hygiene habits.

Teaching emphasis: establish the consciousness of loving and caring for eyes, and develop good eye hygiene habits.

Teaching content:

Myopia is a kind of ametropia. The performance is to see clearly what is near, but not what is far away, because the light entering the eyeball cannot focus on the retina, but falls in front of it. Bad visual environment, insufficient light when reading and writing, too long time of using eyes at close range and incorrect reading and writing posture are the important reasons for the occurrence or development of myopia. To protect eyesight and prevent myopia, we must understand the basic knowledge of myopia prevention, establish like eyes's awareness of eye protection, and develop good eye hygiene habits.

First, keep correct reading and writing posture.

1. Sit up straight when reading and writing. Keep the distance between the eyes and the book at about 33-35 cm (one foot), the distance between the chest and the table at about one punch, and the distance between the finger holding the pen and the nib at about 3 cm (one inch).

2. When writing, hold the pen at an appropriate angle. When writing with a pencil or pen, the angle between the pen and paper is between 40 degrees and 50 degrees. When writing with a brush, try to keep the pen upright.

3. Don't read with your head tilted or lying down, don't walk, and don't read in a rickety car or boat.

(1) Visual environment requirements for reading and writing.

1. There should be enough light when reading and writing, and the window light and desk light should come from the left front. Don't read or write in too bright or too dark light (such as direct sunlight or insufficient light at night).

2. Try not to write your homework with pencil lead's pen. Lead core should be moderate in hardness, homework paper should be clean, and the writing font should not be too small.

3. Choose a suitable desk and chair to read and write, and the height of the desk should be near the upper abdomen.

(2) Visual environment requirements for watching TV.

1. When watching TV, people should keep a distance of more than 3 meters (or keep a distance of more than 5 times the diagonal of the TV screen).

2. The height of the TV screen should be parallel to or slightly lower than the line of sight of TV viewers.

The TV should be placed in the backlight.

The brightness of the TV should be appropriate, neither too bright nor too dark.

(3) Requirements for operating computer vision environment.

1. It is best to turn your back to the window or sideways to avoid reflection.

2. The computer console should be lower than the height of the general desk, and the seat should be adjustable. The center of the computer screen should be at the same level as the chest.

3. The distance between the computer screen and eyes should be not less than 50 cm, and the line of sight should be slightly lower than the horizontal line of sight 10-20 degrees.

4. The light in the computer operation room should not be too weak or too strong (12 square meter room, a 40-watt fluorescent lamp can achieve the required illumination).

Third, develop good eye hygiene habits.

1. The continuous use time with eyes closed should not be too long, and should be controlled at 40-50 minutes. Pay attention to relax your eyes when resting, and go outside the classroom or near the window to look down or close your eyes.

2. Watching TV or operating the computer for too long. After watching TV or operating the computer for about 40-50 minutes, you should have a rest, or close your eyes or do eye exercises, or exercise outdoors or overlook.

3. Don't play or play less video games. Pay attention to the distance between your eyes and the game machine when you play occasionally, and the duration should not exceed half an hour.

Fourth, insist on doing eye exercises.

1. Do eye exercises every morning and afternoon.

2. Pay attention to clean hands when doing eye exercises, so as to achieve accurate acupoint selection, correct technique and appropriate strength.

Ensure sleep, balance nutrition and strengthen exercise.

1. Get enough sleep and make sure your eyes get enough rest. Pupils sleep 10 hours a day, junior high school students sleep for 9 hours and senior high school students sleep for 8 hours.

2. Not picky about food, not partial eclipse, balanced diet, and comprehensive nutrition.

3. Eat more fruits and vegetables, and often eat foods rich in vitamin A (such as carrots, spinach, animal liver, apricots, loquat, etc.). ).

4. Go to outdoor activities, participate in ball games, observe flowers and trees, appreciate the green mountains and green waters of nature, and relax the ciliary muscles.

6. Check your eyesight regularly and wear appropriate glasses.

1. Check your eyesight twice every semester. When the eyesight drops, you should go to the hospital ophthalmology department for further examination as soon as possible.

2. If you are diagnosed with myopia, you should go to the hospital for optometry and glasses in time. Don't go to an informal optical shop to get glasses. Don't pursue too high corrected vision, which can reach 5.0.

Don't borrow glasses from each other. Everyone's refractive power and pupillary distance are different. Borrowing glasses from each other will cause eye fatigue and other symptoms, affecting vision, which is harmful and useless.

4./kloc-Children under 0/6 should be cautious when wearing contact lenses.

Specific requirements for students: 1. Develop and maintain correct reading and writing posture. 2. Choose a good visual environment when reading and writing. 3. Develop good eye hygiene habits in daily life and daily study. 4. Insist on doing eye exercises. 5, get up early and go to bed early, ensure adequate sleep time, pay attention to balanced nutrition, and strengthen exercise at ordinary times. 6. Check your eyesight regularly and wear appropriate glasses.

Homework: according to the above specific requirements, see what you have achieved, what you have not achieved, and what you will do in the future.
