Junior high school health education teaching plan 2 1. Through teaching, students can understand infectious diseases and their prevention.
2, through the bilateral teaching between teachers and students, so as to promote students' enthusiasm and interest in learning, and lay the foundation for the prevention of infectious diseases.
Focus: infectious diseases and their prevention
Difficulties: three links
Teaching AIDS: projection, multimedia classroom
Introduce a new lesson:
In Shanghai, it was caused by eating subcrena subcrenata contaminated by hepatitis A virus. Hepatitis A? Popular. Excuse me, which link should Scapharca subcrenata belong to among the three basic links in the epidemic of infectious diseases? Why?
What measures should be taken to control the epidemic of infectious diseases when introducing the new review course? How to control it? General measures to prevent infectious diseases
In the epidemic of infectious diseases, as long as any one of the three basic links is cut off, its epidemic can be terminated.
1. Control the source of infection:
Many infectious diseases are contagious before the onset, but they are the most contagious in the early stage. How do we usually care for infectious patients? Draw a conclusion according to the students' discussion.
We should try our best to find, report, treat and isolate patients at an early stage to prevent the spread of infectious diseases. Pay more attention to infectious patients and don't dislike them. The patient is in good health.
The mood is conducive to an early recovery. Animals with infectious diseases must be dealt with in time, such as dogs with rabies, even lovely pets, can't stay.
2. Cut off the route of transmission:
A hepatitis patient put a note under the bowl after eating in a restaurant:? I am a hepatitis patient. Please disinfect the used tableware before using it? . Obviously, this is a person with social responsibility. His aim is to cut off the route of transmission. In fact, wash your hands before and after meals to eliminate mosquitoes and flies. , also cut off the route of transmission. Pay attention to personal hygiene, eliminate vectors, etc. Let pathogens have no chance to infect healthy people.
3. Protect vulnerable groups:
Carry out vaccination to improve the disease resistance of susceptible people. In addition, it is also important to take an active part in sports and enhance physical fitness in disease prevention.
Different infectious disease prevention methods are also different, mainly to find out its weak links and adapt to the disease. Human infectious diseases:
There are many kinds of infectious diseases. According to the different transmission routes, there are mainly the following categories:
1. Respiratory infectious diseases:
Provide an outline of thinking, let the students discuss in groups, and finally the teacher summarizes the textbook.
(1) What diseases do you think are respiratory infectious diseases?
(2) Respiratory infectious diseases often occur in what season?
(3) What is the main source of infection? Note that the carrier is the source of infection, although he is not sick and has no symptoms. )
(4) Where are the main parasitic parts of pathogens?
(5) What is the main route of transmission of respiratory infectious diseases?
(6) What is the significance of prohibiting spitting and keeping the classroom air circulating to prevent respiratory infectious diseases?
2. Infectious diseases of digestive tract:
Infectious diseases of digestive tract are infectious diseases caused by pathogens invading digestive tract mucosa. Do a good job before class, and invite students who have had dysentery, hepatitis and ascariasis, or students who have had such patients at home and are familiar with the disease, to introduce the main symptoms and how to get infected with the disease. What main measures have been taken in the treatment, what lessons have been learned after the illness, and how to prevent it in the future.
Students of the following two infectious diseases have less perceptual knowledge, which is mainly explained by teachers.
3. Blood infectious diseases:
Mainly refers to infectious diseases caused by mosquitoes, lice, fleas, ticks and other media, so it is also called insect-borne infectious diseases. Because students rarely see lice, fleas, ticks and so on. , it is best to have wall charts, photos or videos to assist teaching, so as to enhance the intuitive effect.
Briefly introduce malaria, Japanese encephalitis, kala-azar, filariasis and hemorrhagic fever, or introduce them by video and other media.
The source of infection is patients and animals with pathogens; The original parasitic parts of pathogens are blood and lymph; The route of transmission is biological medium. Preventive measures are mainly to cut off the route of transmission and eliminate mosquitoes and lice.
4. Infectious diseases on the body surface:
Mainly refers to direct or indirect contact with sick people and animals, or contact with soil and water containing pathogens, pathogens enter the human body through the skin and cause infectious diseases, so it is also called contact infectious diseases. Briefly introduce tetanus, rabies, schistosomiasis, trachoma, scabies, tinea and other infectious diseases with photos or videos. One or two species can be introduced according to local conditions, especially tetanus, schistosomiasis and trachoma.
Pathogens are parasitic on skin and body surface mucosa. Mainly through contact, pay attention to isolate patients, do a good job of personal hygiene, do not use public towels and washbasins, do not contact animals with pathogens, and it is best not to keep pets such as cats and dogs.
Conclusion: It is best to contact the prominent infectious diseases in this area and give systematic theoretical guidance in combination with the reality that students are familiar with. In the long run, it will help students improve their quality of life in the future.
