[Key Tips]

1, COVID-19 prevention

At present, the global epidemic of Omicron mutant in COVID-19 is highly contagious, and there are also many endemic epidemics in China, with a wide range and high frequency. The situation of epidemic prevention and control is severe and complicated, facing the dual risks of local epidemic spread, overseas import and subsequent spread. It is suggested that those who meet the requirements but have not been vaccinated with COVID-19 vaccine should be vaccinated as soon as possible, those who have not been vaccinated in the whole process should be vaccinated as soon as possible, and those who have completed basic immunization for more than 6 months should be vaccinated as soon as possible. Avoid going to epidemic areas and high-risk areas; Avoid unnecessary cross-border travel; Travel is strictly restricted in high-risk areas and counties where China epidemic occurs; Personnel from other counties in the city where the high-risk area is located must not travel unless necessary. If it is really necessary to travel, they must hold a negative certificate of nucleic acid test within 48 hours; It is strictly restricted to go to middle and high risk areas and counties, and it is not necessary to go to other counties in the city where the middle and high risk areas are located. Other areas try to reduce unnecessary travel and gathering, especially the elderly, patients with basic diseases, pregnant women and other people. During the trip, you should obey the relevant requirements of the prevention and control work in COVID-19, the destination of the trip, and prepare masks, hand-free disinfectant, disinfectant wipes and other items.

[Characteristics of related risks and specific preventive measures]

1, novel coronavirus

At present, the local epidemic in COVID-19 has spread on a large scale in China, and the community communication in some areas has not been blocked. The epidemic situation is spillover, and the internal non-proliferation situation is severe and complicated. The global epidemic in COVID-19 is still at a high level. Influenced by multiple factors, such as Omicron mutant becoming the dominant epidemic strain in the world, relaxation of travel restrictions and prevention and control measures in many foreign countries, there is still a great risk of importing from abroad and causing local transmission in China.

Main preventive measures

● It is suggested that those who meet the requirements and have not been vaccinated with COVID-19 vaccine should be vaccinated as soon as possible, those who have not been vaccinated in the whole process should be vaccinated as soon as possible, and those who have completed basic immunization for more than 6 months should be vaccinated as soon as possible.

● At present, the foreign epidemic situation is still at a high level. China adheres to the prevention and control strategy of foreign defense input, and requires strict quarantine measures for entry personnel. It is recommended not to leave the country for non-essential or emergency reasons, and to reduce the cross-border flow of people for non-essential reasons such as tourism. During the period of centralized isolation and home health monitoring, entry personnel should strictly abide by local epidemic prevention regulations and do a good job in nucleic acid detection and health monitoring. If you have fever, dry cough, fatigue, sore throat, hypoesthesia, diarrhea and other symptoms. , should immediately notify the corresponding staff and cooperate with medical treatment. Don't go out unless necessary during family health monitoring, and keep a certain distance from the people who live together; If you really need to go out, do personal protection, wear N95/KN95 protective mask, keep a certain distance from others, avoid taking public transportation, not attending gatherings such as dinners, exhibitions, tourism and training, not going to schools, factories, welfare homes, nursing homes, shopping malls, supermarkets, office buildings, playgrounds, large farmers' markets, cinemas and other crowded places, and not going to chess rooms and cinemas.

If it is really necessary to travel, they must hold a negative certificate of nucleic acid test within 48 hours. It is strictly restricted to go to middle and high risk areas and counties, and it is not necessary to go to other counties in the city where the middle and high risk areas are located. Other areas try to reduce unnecessary travel and gathering, especially the elderly, patients with basic diseases, pregnant women and other people.

● Fever patients, health code "yellow code" and other personnel should fulfill their personal protection responsibilities, actively cooperate with health monitoring and nucleic acid detection, and do not travel before the risk of infection is eliminated. People in high-risk positions in China try to avoid traveling. Those who really need to travel must have been away from work 14 days or more, and have negative nucleic acid test certificate within 48 hours, and report to their unit.

● Strengthen self-protection during holidays. Keep masks, hand washing disinfectant, disinfection wipes and other items. Wear a mask when going out, keep a social distance from others, wash your hands frequently, and cover your nose and mouth when sneezing. Pay attention to the ventilation of the living place. At the same time, try to avoid activities in places where people gather, the space is closed and the ventilation is poor. Don't take part in large-scale party activities, and the party that really needs to be held should be as small as possible.

● Before going out, if you have respiratory symptoms such as fever and cough, you should temporarily suspend your travel plan, and seek medical attention for nucleic acid detection and risk investigation in time under the condition of good protection. During the journey, when traveling by plane, train and other means of transportation, you should abide by the requirements of order and crew management, wear masks throughout the journey, do a good job of hand hygiene, properly keep the bills for enquiry, and abide by the regulations on epidemic prevention and control at the destination; If you have symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell, diarrhea, etc. During the trip, you must cancel or suspend the trip, and immediately go to the nearest medical institution for nucleic acid testing and risk investigation. After returning from tourism, we should continue to do a good job in personal health monitoring. You should keep self-observation 14 days. If you feel unwell, you should seek medical advice promptly and actively inform the doctor about the relevant exposure or travel history. In universities or enterprises with a large number of migrant workers, students or migrant workers need to provide negative proof of nucleic acid test according to the requirements of the unit before returning to school or taking up their posts.

Policy of coming to Wei

1. Visitors from counties where epidemic areas and high-risk areas are located, please communicate with the town or community where the destination is located in advance, and conduct closed-loop management of centralized isolation for 7 days and home health monitoring for 7 days after returning.

2. Tourists in the county where the medium-risk area is located should communicate with the town or community where the destination is located in advance, and conduct closed-loop management of home health monitoring for 7 days after returning.

3. Visitors from other counties in prefecture-level cities and low-risk areas where high-risk areas are located should report to the community where their destination is located, and conduct 1 nucleic acid testing on the second and fourth days after landing sampling. On the fourth day, before the nucleic acid test results came out, the public place code was gray; If the nucleic acid test results are all negative, the public place code turns green.

4. If the truck drivers and passengers come to Wei, please ask the drivers and passengers or pick-up enterprises to report through the "comprehensive epidemic prevention and control management system" of our city and cooperate with the implementation of control policies.

2. Norovirus enteritis

The outbreak of norovirus enteritis mostly occurs in schools, kindergartens, hospitals, nursing homes, large cruise ships and other crowded places, as well as on airplanes or tour groups. Transmission routes include interpersonal transmission, food transmission and water transmission. Human-to-human transmission is through the fecal-oral route, including inhaling the aerosol generated when the patient vomits, touching the patient's vomit or feces, and touching the surface of environmental objects contaminated by the patient's vomit or feces. Foodborne transmission is spread by eating food contaminated with norovirus. Contamination can occur when catering workers infected with norovirus contaminate food in the process of preparing and serving meals, or when food is contaminated by infected excrement or other substances containing norovirus in the process of production, transportation and distribution. Shellfish such as oysters, raw fruits and vegetables are also common foods that cause infection. Pollution of other drinking water sources such as bottled water, municipal water supply and well water can also lead to water transmission. The most common clinical symptoms are vomiting and diarrhea, followed by nausea, abdominal pain, headache, fever, chills and muscle pain. Most patients can recover within 2-3 days after onset. Very few cases can lead to serious illness or even death.

Main preventive measures

● Pay attention to personal hygiene, especially hand hygiene. Wash your hands frequently before and after meals, after going out to take care of patients, before preparing or distributing food and eating.

● Pay attention to the hygiene of diet and drinking water. When eating out, you should choose a regular restaurant with good sanitary conditions, try to eat cooked food, wash raw fruits and vegetables, and thoroughly cook shellfish such as oysters before eating; Don't drink raw water.

● It is best to isolate Norovirus-infected people at home within 3 days after onset, and try not to have close contact with other healthy family members, especially not to prepare and process food or take care of the elderly and babies.

● The surface contaminated by patients' vomit or feces should be cleaned and disinfected with chlorine bleach or other effective disinfectants in time, and the contaminated clothes or sheets should be taken off immediately for cleaning. Wear rubber or disposable gloves when cleaning and wash your hands carefully after cleaning.

3. Food poisoning

May-10 is the high incidence month of food poisoning in China. During holidays, the chances of gathering and eating out increase, and the risk of food poisoning increases accordingly. Food poisoning caused by microorganisms is the most common in Chinese mainland, and other poisoning such as wild bacteria and wild plants also occurs from time to time. Food poisoning usually occurs in a short time after eating, with gastrointestinal symptoms such as nausea, vomiting, abdominal pain and diarrhea.

Main preventive measures

● Keep clean, wash your hands frequently before and after meals, before and after handling raw and cooked food and its packaging, after touching pets and disposing of garbage; Tableware and kitchen utensils should be washed and dried with flowing safe water, and often cooked and disinfected, and the kitchen environment should be clean. Raw and cooked food should be separated, and kitchen utensils and containers for processing food should be separated. Use safe water and food raw materials, choose fresh vegetables and fruits, staple food, mildewed beans and peanuts, and wash and peel them properly to reduce risks; Safe water should be used in the whole process of food production. Food should be thoroughly cooked and burned, and leftover food and overnight food should be thoroughly heated before eating. Keep food at a safe temperature. Cooked food should not be stored for more than 2 hours at room temperature. Foods that cannot be eaten in time should be refrigerated or frozen. Cooked food should be kept above 60℃ before eating. When eating out, you should choose a regular restaurant with good sanitary conditions, maintain a good way of eating, try to use separate meals, advocate the use of public chopsticks and spoons, and reduce the risk of cross-contamination. Don't eat food of unknown origin, don't collect or eat unknown wild mushrooms and plants.

4. tick-borne diseases

Ticks are the vectors of many infectious diseases and often transmit pathogens to people through bites. April-September is the active period of ticks in most parts of China, and the probability of people being bitten by ticks is obviously increased. Ticks live in grasslands, bushes or woodlands and animals. People may be in close contact with ticks when walking dogs outdoors, camping, gardening, picking tea, farming or hunting, or they may be in contact with ticks in the yard or community. Ticks are often attached to the scalp, waist, armpits, groin, ankles and other parts of the human body, and the worms swell as big as soybeans after being filled with blood. Ticks can cause allergies, ulcers or inflammation after biting people, which is generally mild; However, some infectious diseases spread by ticks, such as fever with thrombocytopenia syndrome and Xinjiang hemorrhagic fever, have a high mortality rate. Diseases transmitted by ticks often have similar symptoms in the early stage. Fever and chills are the most common symptoms, followed by itching, headache, fatigue and muscle pain. Some people may have joint pain and rash.

Main preventive measures

● Personal protection should be done in outdoor activities, such as wearing long-sleeved underwear, tightening trouser legs, and applying repellent to bare skin to avoid sitting and lying in the main habitats of ticks such as grass and Woods for a long time to prevent ticks from biting. Once ticks are found attached to the skin, they should be removed as soon as possible. You can spray alcohol on the tick to relax or kill the tick's head, and then take it out with clean fine-pointed tweezers. Don't pull it hard to avoid hurting the skin or leaving the tick's head in the skin. After taking it out, it should be disinfected locally with iodine or alcohol, and the physical condition should be observed at any time. Consult medical staff in time if necessary. If you have symptoms such as fever, fatigue and muscle aches within a few weeks after clearing ticks, you should seek medical advice as soon as possible and inform the doctor about the relevant exposure history.

5. Infectious diseases of animal origin

Humans may be infected with animal-borne infectious diseases such as avian influenza, brucellosis and anthrax through contact with animals, eating undercooked animal products and contacting with animal habitat environment.

Main preventive measures

● Avoid entering the habitats of wild birds and other animals, and do not touch or eat wild animals. Try to avoid direct contact with any animals, especially those of unknown origin. Don't eat undercooked meat, eggs, milk and other animal products. Choose fresh and safe animal food raw materials, and pay attention to the separation of raw and cooked food during processing.
