Template for theme class meeting of infectious disease prevention bank.

Spring is the peak of infectious diseases. If you don't pay attention to exercise at ordinary times, the indoor air will not circulate, which will easily lead to the prevalence of respiratory infectious diseases. The following is a class meeting on the prevention of infectious safety organized by me and our bank, hoping to provide you with reference.

Fan, the theme class meeting of our bank is accompanied by the prevention of infectious safety.

Recently, the flu has spread widely in schools, which has a serious impact. Spring is a season of high incidence of various common diseases due to abnormal climate change, which is highly contagious and spreads quickly. I hope that through this theme class meeting, students can understand the prevention knowledge of infectious diseases in spring, effectively prevent the occurrence of infectious diseases in spring, and devote themselves to their studies with healthy body and mind.

First, the seasonal causes of high incidence of infectious diseases

At the turn of winter and spring, it is too late for the internal system of human body to adapt to climate change. In addition, the weather is hot and cold in early spring, and the temperature difference between morning and evening is large. The human immune system has no time to adjust and adapt to external changes. Viruses, bacteria, fungi and other pathogenic microorganisms are often more active than in winter, so they are easy to get sick.

Second, common infectious diseases in spring:

1, influenza (flu)

Influenza, referred to as influenza for short, is an acute respiratory infectious disease caused by influenza virus, which is highly contagious and ranks first among infectious diseases. The incubation period is 1-3 days. The main symptoms are fever, headache, runny nose, sore throat, dry cough, muscle and joint pain and discomfort all over the body. Fever usually lasts for 3-4 days, and some of them are severe pneumonia or gastrointestinal flu.

2. Meningitis (epidemic cerebrospinal meningitis)

Epidemic cerebrospinal meningitis is an acute respiratory infectious disease caused by meningococcus, which is highly contagious. In the early stage of epidemic cerebrospinal meningitis, it is similar to a cold, runny nose, cough, headache and fever. After bacteria enter the cerebrospinal fluid, serious symptoms such as headache, lethargy, neck rigidity, jet-like vomiting, coma and shock appear.

3, chickenpox

Chickenpox is a highly contagious disease caused by varicella-zoster virus. The typical clinical manifestation of chickenpox is moderate to low fever, and soon red maculopapules appear in batches and quickly develop into clear oval blisters. After 24 hours, the blister becomes turbid and easy to break, then contracts from the center and scabs quickly. Clinically, papules, blisters and scabs often exist at the same time, showing a centripetal distribution, that is, the trunk comes first, followed by the head, face and limbs, while the hands and feet are less and the itching is heavier.

4. Mumps

Commonly known as "gills", an acute systemic infectious disease caused by mumps virus can be cured in about 2 weeks. Typical clinical symptoms are fever, swelling and pain under the ear and chin. Parotid enlargement is characterized by forward, backward and downward spread around the earlobe, which may be complicated with meningoencephalitis and acute pancreatitis. The source of infection is mumps patients or recessive infection, and the virus infects healthy people through droplets. It is more common in children and adolescents, with good prognosis and lasting immunity after illness.

5, rubella

Rubella is an acute respiratory infectious disease caused by rubella virus, and spring is the high incidence season of rubella. At first, there are usually only low-grade fever and mild cold symptoms. Rash usually occurs 0 ~ 2 days after the onset of 65438+, and the shape and distribution of rash are similar to measles. It takes only 1 day for the rash to develop rapidly from the face to the whole body, which is the characteristic of rubella.

Three basic links in the epidemic of infectious diseases

Infectious diseases can spread among people, and there must be three basic links: the source of infection, the route of transmission and the susceptible population. Without these links, infectious diseases would not be prevalent.

1, source of infection

A source of infection refers to a person or an animal that can spread pathogens. Pathogens live and reproduce in respiratory tract, digestive tract, blood or other infectious tissues, and can be directly or indirectly transmitted to healthy people through excreta, secretions or biological media (such as mosquitoes, flies, lice, etc.). The source of infection.

2. Transmission routing

Transmission route refers to the way that pathogens leave the source of infection and reach healthy people. The main ways of pathogen transmission are:

(1) droplet transmission: When students talk, cough and sneeze, they spread germs to others through saliva droplets and air droplets.

(2) Dust transmission: The patient's sputum and nasal mucus contain a large number of germs. Because I usually don't pay attention to hygiene, I spit everywhere and twist my nose.

When these dirty things are dry, bacteria are entangled in dust and fly around with the air. In this way, if inhaled by healthy people, it will be infected.

(3) Direct contact transmission: Hands are the most direct way to spread germs. During the epidemic of infectious diseases, patients have many germs on their hands.

The surface of the objects they touch will leave a lot of germs. If healthy people don't pay attention, they come into direct contact with the patient's belongings, which is the bacteria that may enter the respiratory tract from the nasal cavity and cause infection.

3. Susceptible population: Susceptible population refers to people who lack immunity to an infectious disease and are susceptible to the disease.

Let's take the epidemic of influenza as an example to illustrate the three basic links of 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.

Fourth, prevention of infectious diseases.

Different infectious diseases have different treatments, but the basic preventive measures are the same. As long as we pay attention to the following points, we can effectively reduce the occurrence and spread of diseases.

1, reasonable diet, increase nutrition, drink plenty of water, take in enough vitamins, and eat more foods rich in high-quality protein, sugar and trace elements, such as lean meat, eggs, dates, honey, fresh vegetables and fruits; Take an active part in physical exercise, go to the suburbs and outdoors to breathe fresh air, walk, jog, do exercises, punch, etc. Every day, so as to make the body's blood flow smoothly, stretch the bones and muscles, and enhance physical fitness;

2. Don't go to places with dense population, mixed personnel and air pollution such as farmers' markets, individual restaurants and recreation rooms;

3. Always wash your hands thoroughly with running water, including wiping your hands without dirty towels;

4. Open the window for ventilation every day to keep the indoor air fresh, especially in dormitories, computer rooms and classrooms.

5, reasonable arrangement of work and rest, make life regular; Be careful not to be overtired to avoid catching a cold and reducing the disease resistance;

6, do not eat, do not process unclean food, refuse to eat all kinds of seafood and meat raw, and eat fruits with skin, do not drink raw water. Don't take the garbage out casually, don't pile it up casually, and the garbage should be destroyed in a unified way;

7, pay attention to personal hygiene, don't spit and sneeze casually;

8. Students should learn to conduct self-observation. If they feel unwell, such as fever, general pain, headache, vomiting and cough, they should tell their parents or teachers in time to ensure early detection and treatment.

Fan, the theme class meeting of our bank is accompanied by the prevention of infectious safety.

First, the purpose of the theme class meeting:

Through this class meeting, the students realized that it is the key to prevent infectious diseases in spring to pay attention to personal hygiene and protection at school and develop good hygiene habits at home.

Second, the theme class meeting activities preparation:

1. Arrange the host and activity steps in advance.

2. Arrange students to participate in activities and tell stories in advance.

3. Write "Healthy and Happy Life" on the blackboard before class;

Third, the process of the theme class meeting:

1. A host announced the class meeting:

Introduction: Spring and March, when everything recovers, are the best seasons of the year, and also the transition period from cold winter to hot summer. The climate in spring is often changeable, with sunny days and warm spring winds. After a period of time, it rained continuously and it was freezing, so some people called it the season of "a hundred herbs sprouting and all diseases erupting". Every spring, the outpatient departments of major hospitals are often overcrowded, with rhinitis, flu, pneumonia, measles, heart disease, mental illness and so on. It happened suddenly, so some people call spring "sick spring" So, how can we effectively prevent diseases in spring?

2. Performing the sketch "physical education class"

After reading the sketch, the students talk about their usual practices.

4. The performance of the essay "Shuang"

5. Three measures to prevent diseases in spring:

① Enhance physical fitness. Mainly to participate in outdoor sports activities, including various physical exercises and manual labor, to enhance the body's immunity. For example, you can take part in running, playing ball, doing exercises, playing Tai Ji Chuan and going out for an outing according to your hobbies.

② Regulate emotions. In spring, it is advisable to supplement some diets rich in phenylethylamine and caffeine, such as green tea, coffee, bananas and chocolate. These foods can excite the nervous system, eliminate fatigue and prevent "spring sleep" and depression. In addition, don't overdo it, and try to be calm and emotionally stable.

③ Take necessary preventive measures. When the weather is changeable, preventive treatment can be given to some chronic diseases under the guidance of doctors. Patients with hypertension, coronary heart disease, diabetes, tuberculosis, rheumatism and psychosis should not stop taking drugs or reduce drugs in spring, but need to strengthen or make necessary adjustments to prevent their illness from getting worse or recurring. Parents should vaccinate their children against infectious diseases in time, and don't take them out of public places casually.

Fourth, the class teacher's summary: Pay attention to personal hygiene and protection at school and develop good hygiene habits at home, which is the key to prevent infectious diseases in spring. In spring, the temperature difference between day and night is large, so clothes must be increased or decreased according to the weather change. Wash your hands before and after meals, clear your nose when sneezing and coughing, change, wash and dry clothes and bedding frequently when you come out, never spit everywhere, and keep indoor air circulation at home. In the season when respiratory infectious diseases are prevalent, it is necessary to reduce gatherings and go to public places less. In spring, the metabolism of the human body begins to flourish, which is a good time to exercise. We should take an active part in physical exercise and combine work and rest. In addition, it is also important to go to bed early and get up early, and to keep enough rest and sleep, which is very important to improve your resistance. Finally, I wish you good health and happy study!

Teaching methods: explanation and discussion

First, common infectious diseases in spring

Spring is the season of high incidence of respiratory infectious diseases. Because the weather is changeable, it is warm and cold, and the climate is still cold and dry, especially in the north, people have experienced a long winter. When spring comes, it is difficult for the internal environment of the human body to adapt to the external environment at once, and the human immunity is relatively low. Pathogenic microorganisms such as germs and viruses take the opportunity to enter and invade the human body, which is particularly easy to cause respiratory infectious diseases such as influenza, meningitis and mumps. At the same time, with the warming of the temperature, it is easy to cause respiratory infectious diseases such as influenza, meningitis and mumps. If you don't pay attention to exercise at ordinary times, the indoor air will not circulate, which will easily lead to the prevalence of respiratory infectious diseases.

flu

Influenza, referred to as influenza for short, is an acute respiratory infectious disease caused by influenza virus, which is highly contagious. Influenza viruses are divided into three types: A, B and C.

Transmission route: it is mainly transmitted directly through air droplets, or indirectly through items contaminated by viruses.

Main symptoms: fever, body aches, sore throat, cough and other symptoms.

Susceptible population: people are generally susceptible to influenza, and have certain immunity after illness, but the duration is not long, and the virus constantly mutates, which can cause repeated infections.

Preventive measures: influenza vaccination has been recognized by the international medical community as the most effective weapon to prevent influenza. Due to the rapid variation of influenza virus, the epidemic types are usually different every year. Therefore, vaccination with the latest influenza vaccine every year can achieve preventive effect. In addition, physical exercise, strengthening physical fitness, often opening windows for ventilation during the flu season, keeping the indoor air fresh, and the elderly and children going to crowded places as little as possible are also effective measures to prevent influenza.

measles

Measles is an acute respiratory infectious disease caused by measles virus, which mainly occurs in winter and spring. People who have not been vaccinated against measles will get sick after contact, and the incidence rate of children aged 1-5 is 65438.

Transmission route: the patient is the source of infection, and measles virus exists in the secretions (such as tears, runny nose, sputum, etc.) of the patient's conjunctiva, nose, mouth and pharynx. ), urinating blood.

Main symptoms: the incubation period of measles is 10- 1 1 day. At first, the symptoms were like a cold, but at the same time, more serious symptoms appeared, such as jealousy, eyelid swelling, tears, fear of light, sneezing and coughing. On the fourth day, rose-colored maculopapules began to appear behind the ears, and the rash spread to the whole body within 2-3 days, and then the rash subsided and peeled off. Other symptoms also gradually subsided.

Susceptible population: the population is generally susceptible, mostly in infants, but in recent years, due to the widespread vaccination of measles vaccine, the age of onset has a tendency to move backwards.

Preventive measures: Minimizing contact with patients and their families is the key to prevent measles. Do a good job in health care, vaccinate measles vaccine on time, circulate indoor air, go to public places less in epidemic season, exercise and enhance disease resistance.

chickenpox

Chickenpox is an acute infectious disease caused by varicella zoster virus. Chickenpox patients are mostly 1- 14-year-old children. It is most likely to occur and be popular in kindergartens and primary schools. Although chickenpox is an acute infectious disease, it is usually mild and will not cause serious complications.

Transmission route: Chickenpox is mainly transmitted through respiratory tract through droplets, and it may also be infected through contact with dust, clothes and utensils contaminated by virus.

Main symptoms: After the chicken pox virus infects the human body, after an incubation period of about 2 weeks, the patient may have early symptoms such as headache, general malaise, fever and loss of appetite. Then there is a characteristic red macula, which later becomes a papule and then develops into a blister, often accompanied by itching. After 65,438+0-2 days, the patient began to dry up and scab for about a week. Rash is most common in trunk, followed by head and face, less in limbs, less in palms and soles.

Susceptible population: The population is generally susceptible. It is common in children aged 2- 10, and can obtain high lifelong immunity with one attack.

Preventive measures: Vaccination with varicella vaccine is the most effective and economical preventive measure. During the epidemic, children should not go to crowded public places, and it is also important to open windows frequently for ventilation.

epidemic parotitis

Mumps is an acute respiratory infection, which is spread by droplets. It is easy to occur in winter and spring, and it is more common in children.

Transmission route: the patient is the source of infection, mainly through droplets, and a few indirectly through instruments, which is highly contagious.

Main symptoms: The symptoms of this disease are mostly acute, including fever, chills, headache and sore throat. The parotid gland of one or both ears of the patient is swollen and painful, especially when chewing. Complications include meningitis, myocarditis, oophoritis or orchitis. The whole course of the disease is about 7- 12 days.

Susceptible population: it is more common in children and adolescents aged 5 ~ 15. Once infected, you can get lifelong immunity.

Preventive measures: isolate the patient in time until the swelling goes down. Vaccinate against mumps.

epidemic meningitis

Abbreviation: Meningitis is an acute respiratory infectious disease caused by diplococcus.

Transmission route: mostly respiratory droplet infection.

Main symptoms: upper respiratory tract infection at first, and most patients have no obvious symptoms. Then the patient suddenly chills, with a high fever of 40℃, repeated headache and vomiting, bleeding spots or ecchymosis on the skin in the early stage, meningitis within 1-2 days, persistent high fever, severe headache, frequent vomiting, convulsions and even coma.

Susceptible population: The population is generally susceptible. The incidence of children is high.

Preventive measures: Immunization is the main measure to prevent meningitis, and the vaccination target is 1- 15-year-old children.

hand-foot-and-mouth disease

Hand-foot-mouth disease (HFMD) is a common infectious disease in children caused by various enteroviruses.

Transmission route: it is mainly transmitted by droplets in the digestive tract or respiratory tract, and can also be infected by contact with patients' skin and mucosal herpes fluid.

Main symptoms: fever symptoms first, maculopapules and herpes on palms and soles (redness around rash), herpes and/or ulcers on oral mucosa, and obvious pain. Some patients may be accompanied by cough, runny nose, loss of appetite, nausea, vomiting, headache and other symptoms. A few patients are seriously ill and may be complicated with encephalitis, meningitis, myocarditis and pneumonia.

Susceptible population: infants are generally more common, and infants aged 3 and below are more likely to get it. Adults usually don't get sick after infection, but they can transmit the virus to children.

Precautionary measures: Wash hands frequently and ventilate frequently, and avoid going to public places with crowded people and poor air circulation during the epidemic. Children with related symptoms should go to regular medical institutions in time.

Highly pathogenic avian influenza (HPAI)

Human infection with highly pathogenic avian influenza is an acute infectious disease caused by highly pathogenic avian influenza virus, mainly manifested as respiratory tract damage.

Transmission route: Avian influenza is mainly transmitted through the air. The virus spreads through secretions, excreta, blood, organs, tissues, drinking water, environment, clothes, eggs and so on. Sick birds, which cause environmental pollution, can also be infected through digestive tract and skin wounds.

Main symptoms: The incubation period of human avian influenza is generally 1-7 days, and the early symptoms are similar to common influenza, mainly including fever, runny nose, sore throat and cough. The body temperature can reach above 39℃, accompanied by body aches, and some patients may have nausea, abdominal pain, diarrhea and conjunctivitis.

Susceptible population: it is possible to be infected at any age, but generally speaking, the incidence rate of children under 12 is higher and the condition is more serious. Close contact with birds who died of unknown reasons or infected or suspected infected with avian influenza is a high-risk group.

Preventive measures: develop good hygiene habits, wash your hands with running water before and after meals, and contact poultry; Pay attention to food hygiene, don't drink raw water, eat eggs thoroughly, and pay attention to the separation of raw and cooked food when processing and preserving food; Do a good job in kitchen hygiene, do not eat raw poultry meat and internal organs, and wash your hands thoroughly after dissecting live (dead) poultry, livestock and their products.

tuberculosis

Tuberculosis, commonly known as "wasting disease" in the past, is a systemic chronic infectious disease caused by the spread of Mycobacterium tuberculosis mainly through respiratory tract. Among them, tuberculosis is the most common, and it can also invade meninges, intestines, kidneys, bones, ovaries, uterus and other organs.

Transmission route: the source of infection is mainly active sputum smear or sputum culture positive pulmonary tuberculosis patients; The route of transmission of tuberculosis is respiratory tract, digestive tract and skin and mucous membrane contact, but it is mainly transmitted through respiratory tract.

Main symptoms: TB usually starts slowly, and the long-term symptoms are fatigue, low-grade fever in the afternoon, night sweats, loss of appetite, weight loss, and menstrual disorders in women. Severe cases may have high fever, chills, chest pain, dyspnea, general failure and other manifestations. Tuberculosis patients are often accompanied by cough, expectoration, and may have bloodshot. Mycobacterium tuberculosis invades the meninges, intestines, kidneys, bones, ovaries, uterus and other organs, which may cause symptoms such as headache, vomiting, disturbance of consciousness, emaciation, diarrhea and constipation, hematuria, pyuria, splenomegaly, anemia and gynecological diseases.

Susceptible population: people who are generally susceptible but have close contact with tuberculosis patients; People with weak resistance to tuberculosis, such as children, the elderly, malnutrition, pneumoconiosis, diabetes, HIV-positive or AIDS patients, are the key groups.

Preventive measures: First of all, improve immunity, strengthen exercise and ensure adequate nutrition. Infants and young children should be vaccinated with BCG vaccine on time to gain immunity. Secondly, attention should be paid to indoor ventilation to avoid close contact with patients with infectious tuberculosis who have been diagnosed. Thirdly, actively and effectively treat diabetes, silicosis, whooping cough and other basic diseases that are easy to induce tuberculosis.

Second, the common methods to prevent the spread of infectious diseases in spring:

Infectious diseases are mainly spread through food, nose and mouth droplets and contact.

Ventilation: Fresh air can remove excessive moisture and dilute indoor pollutants. Windows should be opened regularly for ventilation to maintain air circulation; Let the sun shine indoors, because the ultraviolet rays in the sun have bactericidal effect; You can also fumigate the room with vinegar to achieve disinfection effect.

Wash your hands frequently: respiratory secretions and excreta such as nasal mucus, sputum and droplets of patients with infectious diseases contain a large number of pathogens, which may be transmitted to healthy people through hand contact with secretions and excreta, so special attention should be paid to hand hygiene.

Drink plenty of water: Especially when the climate is dry, the dust content in the air is high and the human nasal mucosa is easily damaged. Drinking plenty of water and keeping the nasal mucosa moist can effectively resist the invasion of viruses, facilitate the excretion of toxins in the body and purify the environment in the body.

Supplementary nutrition: appropriately increase the intake of water and vitamins. Pay attention to supplement foods with high nutritional value such as fish, meat, eggs and milk to enhance the immune function of the body; Eating more fresh vegetables and fruits rich in vitamin C can neutralize toxins in the body, improve disease resistance and enhance resistance.

Reduce the irritation to respiratory tract: If you don't smoke, drink and eat less spicy food, you can reduce the irritation to respiratory tract.

Avoid catching cold: When the human body catches cold, the blood vessels in the respiratory tract contract, the blood supply decreases, the local resistance decreases, and the virus is easy to invade.

Insist on physical exercise and cold-resistant exercise: appropriately increase outdoor activities, because exercise can not only promote the blood circulation of the body and enhance the cardiopulmonary function, but also be very beneficial to our respiratory system.

Pay attention to the law of life: ensure adequate sleep. Irregular life tends to weaken the function of immune system; Adequate sleep can eliminate fatigue, regulate various functions of the human body and enhance immunity.

Strengthen personal hygiene and personal protection: pay attention to washing hands and gargling frequently, and don't touch your face, eyes and mouth with dirty hands. When going out, try to stand in a place with smooth air. Avoid going to crowded public places.

Early detection, early reporting and early treatment: When one or more respiratory symptoms such as fever, cough, dyspnea and shortness of breath occur to yourself or others around you, you should go to the hospital in time and report to the relevant departments. Don't take things seriously, not to mention taking medicine indiscriminately, so as not to delay diagnosis and treatment, thus delaying yourself and affecting others.

Vaccination: timely vaccination of school-age people can effectively prevent a variety of respiratory infectious diseases. Avoid going to crowded places: the air quality in crowded places is poor and the ventilation is not enough. People in crowded places are more likely to have infectious diseases, so try to avoid going to crowded places.

Just do the following:

1, pay attention to food hygiene, and avoid the disease from entering the mouth;

2, avoid contact with children, child care institutions found patients, to take isolation measures;

3. Strengthen physical exercise at ordinary times;

4, regulate the spleen and stomach, treat food accumulation early.

5, when popular, do a good job in environment, food hygiene and personal hygiene;

1, don't cover your mouth when coughing;

2. Don't fight if you are afraid of vaccination;

3, usually do not pay attention to exercise;

4. Don't wash your hands when eating.

Fourth, students exchange how to prevent infectious diseases:

1, develop good hygiene habits and improve self-prevention ability.

2, strengthen physical exercise, enhance the resistance to infectious diseases.

3. Vaccinate according to regulations to improve immunity.

4, do a good job in environmental sanitation, eliminate the spread of mosquitoes, flies, rats, cockroaches and other pests.

5. Infected patients should be found, reported, diagnosed, isolated and treated early to prevent cross infection.

6, infectious patients contact supplies and rooms are strictly disinfected.
