The contents of primary school epidemic education can be summarized from the following aspects: ** 1. Basic knowledge of infectious diseases ** 1. ** Covid-19 related ** - Covid-19 is a disease caused by coronaviruses. People are generally susceptible to it, including those with low immune function and normal people. It is related to the amount of bacteria exposed. People with poor immune function (such as the elderly, pregnant women, patients with liver and kidney abnormalities or chronic diseases) may be more serious after infection. The main routes of transmission were droplet transmission, contact transmission (hand pollution caused self-contact), and possible airborne transmission. The routes of transmission through the airborne and digestive tract had yet to be determined. - In addition to Covid-19, there were six other crown viruses that were known to infect humans. Covid-19 did not show the terrible characteristics of SARS. It is sensitive to heat. At 56 ° C for 30 minutes, ether, 75% alcohol, chloride-containing disinfectant, peracetic acid, chloride-containing disinfectant, and other fatty liquids can effectively inactivate the bacteria, but the chloride-containing disinfectant cannot effectively inactivate the bacteria. 2. ** Norovirus related ** - Norovirus-infected diarrhea occurred throughout the year, and the season of high occurrence was from November to April of the following year. The incubation period ranged from 24 to 48 hours, with the shortest being 12 hours and the longest being 72 hours. - The main symptoms were nausea, vomiting, abdominal pain, diarrhea, abdominal spasms, and other symptoms of gastroenteritis, as well as headache, fever, chills, muscle pain, and other symptoms of poisoning. It was a self-limited disease, without specific drugs and vaccine. It was mainly based on symptom or supportive treatment, and people who were prone to dehydration needed special attention. - The main route of transmission was the faecal-oral route, such as direct contact with the patient's vomit or excrement, contact with objects touched or used by the patient, the smog produced by vomit, contact with contaminated food or water. ** II. Protective measures ** 1. ** In terms of managing the source of infection ** - For infectious diseases (such as the new crown), the reporting system should be strictly implemented. People with infectious diseases should be isolated and treated. The people carrying infectious diseases should be isolated, educated, treated, quarantine and epidemic prevention, and the infected animals should be dealt with. 2. ** In terms of cutting off the transmission route ** - For Covid-19, in public transportation, elevators, shopping malls and other crowded places, we must adhere to the "epidemic prevention three-piece set"(wearing masks, maintaining social distance, and paying attention to personal hygiene). Wearing masks must be worn correctly and changed in time and regularly. Do not take off masks when people are crowded or talking to people. Try to reduce going to crowded places. When returning home, wash your hands and disinfect them frequently. - For Norovirus, one should pay attention to not drinking raw water, drinking boiled water or qualified barreled water, eating raw fruits and washing them, and eating oyster and other seafood after heating and cooking. If there are symptoms of diarrhea and vomiting, use your own utensils and daily necessities, strengthen hand washing, try not to have close contact with family members, do not make food, and do not take care of the elderly and infants. During the illness, disinfect diarrhea or vomit with chloride-containing preparations, and boil food utensils for 30 minutes to disinfect. 3. ** Protecting vulnerable people ** - Non-specific prevention includes improving nutrition (such as balancing diet, ensuring adequate intake of grains, fruits, vegetables, and protein, eating cooked meat and eggs, etc.), strengthening exercise, strengthening physical fitness, improving immunity, etc. - The specific prevention is based on the vaccine (for example, people over the age of 3 years old who are not contraindicated should be "accepted"). Primary school students should pay attention to personal hygiene habits, wash their hands frequently (wash hands with hand sanitizer or soap or running water before meals and after going home), strengthen physical exercise, ensure adequate sleep, and not be picky with food to enhance their immunity; If there are related symptoms (such as nausea, vomiting, diarrhea and other symptoms of Norovirus infection), they should be isolated at home and not enter school with illness. ** 3. School and Family Cooperation in Epidemic Control ** 1. ** School requirements ** - One week before returning to school, teachers and students should do a good job of health monitoring. At home, measure body temperature every day and observe the clinical symptoms related to the infection of the new crown. In case of fever, dry cough, fatigue, sore throat and other symptoms, they should be tested for protein or nuclear acid. If the infection occurs, report to the school truthfully and delay returning to school. After returning to school, health monitoring shall be carried out for 7 consecutive days to reduce congregated activities as much as possible. - Parents should pay close attention to the epidemic situation and epidemic prevention requirements issued by the school, complete all kinds of investigation and reporting in time, and do not conceal, report to the evening, or fail to report. On the way to and from school, they insisted on "two points and one line". They entered the school at the wrong peak. Parents wore masks all the time when picking up and sending their children. They kept a distance of more than one meter. They were not crowded. They picked up and sent them in an orderly manner in the specified area. They did not gather or stay. 2. ** Family related requirements ** - Parents should cooperate with the school to do a good job in epidemic prevention and pay attention to their children's health. If the child has fever, cough, diarrhea, fatigue, smell and taste loss and other symptoms, they should wear a mask to the fever clinic for treatment in time, and report to the school as soon as possible. During the treatment, avoid taking public transportation. Families should open the windows for ventilation frequently, 2 - 3 times a day, 20 - 30 minutes each time. When the temperature is suitable, the windows can be opened frequently. The room should be kept clean and tidy daily, and the garbage should be cleaned in time so that the garbage can not stay overnight. The tableware and countertops for handling imported frozen food, the articles used by patients and visitors, and the tableware should be cleaned and disinfected in time.

The background of a photograph had many effects, both good and bad: * * 1. Benefits ** 1. * * Enhances visual depth ** - Through the difference between the background and the background, the three-dimensional effect and depth of the image could be enhanced. For example, by placing the background element in front of the subject, the audience's line of sight would be directed to the subject. There would be a clear sense of layering between the subject and the background, allowing the audience to feel the distance between the different elements, creating a more interesting visual effect. 2. * * Focus on the main body ** - A suitable background helped to highlight the main character. On the one hand, you can choose an appropriate background element to separate the main body from the background, making the main body more eye-catching. On the other hand, the background element can add layers and texture to the image, providing more details and visual appeal. 3. * * Create environment and background story ** - The background element could provide environmental information and background stories. The background elements such as buildings, scenery, and people could help the audience better understand the scene presented in the image, convey the theme and emotions, and inject more meaning into the image. 4. * * Balance and construct the overall picture ** - The background and the background together affected the image's symmetries, proportions, and overall balance. By properly arranging the position, size, and shape of the background elements, you can create a more artistic and aesthetic composition effect. 5. * * Achievement in photography ** - If the background was chosen properly, it could not only increase the visual artistic conception of the photo, but also add color to the photo, increasing the attractiveness and expressiveness of the photographic work. 6. * * Additional photography theme ** - A suitable background could complement the theme of the photography and cooperate with the main body to construct a complete and story-like image. * * 2. Disadvantages ** 1. * * Distraction ** - If the background was too complicated, messy, had too many colors and patterns, or there were elements unrelated to the subject (such as unrelated figures), it would attract the attention of the audience, making the audience unable to focus on the subject and reducing the attractiveness of the subject. 2. * * Destroy the host's performance ** - A bad background could ruin a good subject. For example, the background color or elements conflicted with the main body, or the background was too complicated to cover up the important features of the main body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
