How to fight the epidemic when traveling on May Day? CDC experts will focus on you.

May Day is coming, and people who have been cats for a long time can no longer live at home. Many people have made travel plans, but some people are worried about missing this rare spring. Can they travel on May Day? What should I pay attention to? See what the experts say.

Is it safe to travel on May Day?

Feng, a researcher at the China CDC, said at the press conference of the joint prevention and control mechanism of the State Council that it is safe to travel during the May Day holiday in most areas where no cases have been reported recently, but there are still new imported cases or local cases every day, so we should be vigilant and be alert to the risk of infection in COVID-19.

Three types of people are not suitable for traveling.

Feng said that it is not recommended for high-risk groups such as the elderly, patients with chronic diseases and pregnant women to travel.

With the growth of age, many immune functions of the elderly will be reduced, and many elderly people still have many diseases, such as chronic obstructive pulmonary disease, diabetes, cardiovascular diseases and so on. These elderly people are easily infected with novel coronavirus, and even have severe cases.

Wang Lijing, an expert from the National Geriatrics Clinical Medical Center of Xiangya Hospital of Central South University, said that novel coronavirus is mainly characterized by fever, which may be accompanied by mild dry cough, fatigue, poor breathing and diarrhea, while other symptoms such as runny nose and expectoration are rare. However, when many elderly people get sick, they may not be accompanied by fever symptoms, and may show clinical symptoms such as fatigue, chest tightness or digestive tract symptoms. In other words, the clinical manifestations of elderly patients are even more atypical, and some patients even take delirium, disturbance of consciousness and other symptoms as the first or early symptoms, which makes people hard to prevent.

Yang, director of the Obstetrics and Gynecology Department of the First Hospital of Peking University, deputy director of the Obstetrics and Gynecology Branch of the Chinese Medical Association, said that there were very few cases of pregnant women infected with COVID-19. Once pregnant women are diagnosed as suspected, they should actively cooperate with doctors to carry out relevant examinations. The radiation dose of chest CT examination is not enough to cause fetal malformation.

At present, there is not enough data to determine the impact of COVID-19 infection on the fetus. The data of pregnant women who suffered from viral pneumonia in the past showed that premature delivery, fetal growth restriction and perinatal mortality increased. Compared with pregnant women without pneumonia, pregnant women with pneumonia have an increased risk of low birth weight, premature delivery and fetal growth restriction.

Pregnant women should always maintain good personal hygiene habits during pregnancy. If you have fever, cough and other discomfort, you should tell the medical staff your epidemiological history truthfully when you seek medical treatment. Hospitals with conditions to treat infected pregnant women suggest setting up special negative pressure isolation operating rooms and neonatal isolation wards.

How to protect yourself when traveling?

Feng reminded friends with travel plans to take precautions from three aspects. First, get ready before going out. It is recommended to travel in the wrong peak, try to avoid popular scenic spots or peak hours of scenic spots, and avoid carrying out some entertainment projects in closed spaces. If you plan to travel across regions, you should choose areas where no cases have been reported recently, and contact the scenic spots in advance to understand the local prevention and control policies, make preparations as required, and also need to prepare some necessary masks and hand disinfectants for use on the road.

The second is to do a good job of protection on the way. Those who take public transport such as airplanes and trains should abide by the order and the management requirements of the crew, always wear masks, do a good job in hand hygiene, and properly keep the bills for enquiry.

The third is to do a good job of protection during travel. In the process of playing, queue up in the scenic spot in an orderly way to keep the interpersonal distance. Of course, we must maintain good hygiene habits, pay attention to cough etiquette, and do a good job in hand hygiene at any time. When staying out, you should choose a hotel with good sanitary conditions. After you check in, you should open the window to ventilate. If you have symptoms such as fever, dry cough and fatigue during the trip, you should go to the nearest medical institution in time.

Feng also reminded everyone to pay attention to diet. When taking transportation, you should try to reduce the number of meals; It is suggested that take-away food should be preferred in scenic spots; If you eat in a restaurant, it is recommended to sit at intervals or eat on the same side and keep a distance of more than one meter from others.

How about May Day dinner?

In view of the current epidemic prevention and control period, can consumers go to restaurants to eat? Feng said that large-scale dinners are still not recommended, and it is not recommended to bring infants who are unable to take care of themselves to class.

"It is recommended to choose a restaurant with good sanitary conditions for ordinary dining, and make an appointment before eating to avoid crowding." Feng said that close contact and gathering are in danger of infection. Before entering the restaurant, you should cooperate with the staff for temperature measurement and registration. If you have fever, don't go into the restaurant.

Feng said that during dining in the restaurant, it is necessary to minimize contact with public facilities, do a good job of hand hygiene, wash hands before and after meals, try to keep personal distance from others when eating, and pay attention to cough etiquette. When many people eat together, it is recommended to use common chopsticks and spoons to reduce the chance of contact and transmission and the risk of infection.

Feng said that large-scale dinners are not recommended. For general dining, it is recommended to choose a restaurant with good sanitary conditions, make an appointment before eating, and eat at the wrong peak to avoid crowding.

Reminder: Anti-virus, wearing a mask and washing hands frequently are the best protection for yourself.

Shi Yi, a researcher at the Institute of Microbiology of China Academy of Sciences, said at the press conference of the joint prevention and control mechanism in the State Council that COVID-19 is a brand-new virus, and the immune system of ordinary people has no memory of COVID-19's immune protection. Usually, after the virus infects the human body, the human immune system will react, thus producing protective antibodies and cellular immune memory.

Shi Yi said that before the vaccine is successfully developed and marketed, public health prevention and control measures are still the main measures to deal with the COVID-19 epidemic, mainly to control the source of infection, cut off the transmission route and protect the susceptible population. The public should wear masks and wash their hands frequently. For infected patients, "early detection, early reporting, early isolation and early treatment" and timely clinical treatment measures can effectively fight against COVID-19 infection.

Recently, colleges and universities in many places have successively announced the start time. Feng suggested that college students should strictly abide by the arrangements of the school and return to campus. If you travel for a long time on the way back to school, you should carry a mask and hand disinfectant with you, wear a mask all the time when you take public transport, do a good job in health monitoring during the journey, and register and manage your health according to the arrangement after you arrive at school. After the class begins, students should take the initiative to measure their body temperature and wear masks before entering the classroom, and keep a safe distance of more than one meter between seats to avoid gathering during their stay in the classroom. Maintain good hygiene habits in the dormitory and avoid close contact. Dormitories are not encouraged to visit each other. When eating, students are advised to bring their own tableware, avoid mixing, keep a certain distance, or eat at intervals and in different periods. Schools should also avoid takeout meals.
