As of 8 a.m. on January 21, 219 cases of new coronavirus pneumonia had been confirmed in Wuhan, Beijing, Guangdong and Shanghai, and suspected cases had been confirmed in Sichuan, Yunnan, Guangxi, Shandong and other provinces and cities. New cases of new coronary viral infections have increased dramatically, after confirmed cases in large and medium-sized cities such as Beijing, Shanghai and Shenzhen. The National Health And Health Commission decided to include pneumonia with the new coronavirus infection in the management of the statutory infectious disease B, and to adopt prevention and control measures for Class A infectious diseases.
At present, there are only two types of Infectious Diseases in China: plague and cholera. Previously included in the category B infectious diseases to take Class A management of SARS, human infection with highly pathogenic avian influenza, pulmonary anthrax. The move means a nation-level battle with the virus has begun.
So what can be done as an individual to prevent pneumonia? NetEase technology has been collated summed up “prevention of new pneumonia, these recommendations are useful, those methods are useless!” for your reference.
The method of relicopic
1, don’t go to Wuhan: can not go to Wuhan, can not do not come out
Zeng Guang, a member of the National Health and Reform Commission’s high-level expert group, said the outbreak was at an early stage and that prevention and control measures must be strengthened so that everyone knows them. We know that the Spring Festival population flow is an important factor, we hope that the crowd can now not go to Wuhan, Wuhan people can not come out. This is not an official call, it is some of the recommendations of our group of experts.
Yuan Guoyong, a member of the National Health and Health Commission’s high-level expert group, also stressed that if you have been to Wuhan, when you come back, we must not ignore, must tell the doctor what the situation, must do targeted measures, because it is not known which animal source is now. This is very important to the family and to the society.
2, wearing a mask: wearing a mask is useful, can block the spread of droplets
Zhong Nanshan, a member of the National Health and Health Commission’s high-level expert group, said that it is not necessary to wear N95 masks, ordinary (surgical) masks can also block the spread of droplets. Yuan Guoyong, a member of the High-level Expert Group of the National Health and Reform Commission, said it was very important that we must wear masks.
Wang Yuedan, a member of the National Health and Health Commission’s high-level expert group, believes that wearing a mask has a role to play in personal protection, because the mask has a protective effect on SARS, this time the virus and SARS have a similar way, wearing a mask may be useful. In addition, the public should pay attention to environmental disinfection, hand cleaning. Some air disinfection devices can be used, such as spraying disinfectants in the air. Pay attention to keep warm, rest, eat high calories easy to digest food, improve their immunity.
3, more clean: hands, mouth, nose, eyes and other hygiene is very important
Yuan Guoyong, a member of the High-level Expert Group of the National Health and Health Commission, said that our eyes, nose and mouth must also pay attention to hygiene.
Keep your hands clean often, especially before touching your mouth, nose or eyes, after touching public facilities such as handrails or doormen, or when your hands are contaminated with respiratory secretions, such as coughing or sneezing. Wash your hands with liquid and water, with hands for at least 20 seconds, with water clear and dry with paper. Cleaning hands with 70 to 80 % alcohol hand liquor is also an effective method if there is no hand washing facility or if there is no visible dirt on your hands . Use paper towels or bent elbows to cover your mouth and nose when coughing and sneezing.
4. Don’t eat game: change eating habits, reject game
Zhong Nanshan said that the new coronavirus outbreak is concentrated in wuhan two districts, both of which have a relatively large seafood market, said to be a seafood market, here is quite a lot of not seafood, but game, after initial epidemiological analysis, through wildlife infection to people have a relatively large possibility.
In recent years, new infectious diseases have become more frequent around the world, such as the more familiar H7N9 avian influenza, Ebola, MERS, and so on. Researchers have calculated that more than 70 percent of new infectious diseases originate from animals.
In the case of SARS, for example, the source was bats, whose viruses spread from bats to beavers to humans eating fruit beavers.
Zeng Guang, a member of the National Health and Health Commission’s high-level expert group, also said that humans should change their eating habits and stop eating game. If all this is done, I think Wuhan will soon subside. Elsewhere, one case is in control, and soon, the pressure is less elsewhere. So we should try to avoid contact with wild animals or eating game in an unprotected state.
5, spring travel cautious travel: do not bring sick work, travel with disease
Zhong Nanshan academician said that if you feel uncomfortable, do not travel in the Spring Festival, especially the body fever, especially in Wuhan. Travel to have a suitable travel situation, if a little fever, a little uncomfortable, it is not appropriate to go out.
Zeng Guang said that a lot of public work, bus ticketing staff, as well as bank counter personnel for the common people, a person may be sick after infection may infect many people, so every industry has to act. Don’t work with the disease, travel with the disease, it is very dangerous.
Three questionable suggestions
1, white vinegar disinfection: white vinegar can weaken the spread of the virus?
Net transmission from the first line of doctors to give everyone’s advice: buy the cheapest white vinegar, open the pot at home to cover the small fire has been cooked intermittently, white vinegar in the acetic acid scattered in the home has a certain disinfection effect, the more cheapacetic acid more.
Li Lei, Ph.D. in Genetics, Chinese Academy of Sciences, believes that vinegar can be sterilized, but the effect is so general that it is almost negligible.
Vinegar sterilization is mainly based on acid, he says. The benefits of fumigation vinegar have 2, changing air PH, and increasing air humidity. The significance of the two is mainly to reduce the air dust and other bacteria attached to the carrier, blocking its transmission path. So in principle, the significance of smoked vinegar is mainly to block the spread.
Zhang Bo, director of the respiratory department of the PLA Air Force General Hospital, believes that the smell of acetic acid in vinegar has a stimulating effect on the mucous membranes of the respiratory tract, especially lead to tracheitis, emphysema, asthma and other patients’ onset or aggravation of the disease. Many people think that vinegar has the effect of disinfection, sterilization, may be because vinegar has acetic acid.
According to a jin vinegar at a time, take the maximum concentration of 3-5%, there are 25 grams of acetic acid, a room volume according to 30 square meters, 3 meters high to calculate, no cubic meters large only 0.3 grams
Another algorithm, 100 flat three rooms a hall disinfection, about 300 cubic meters of space, need to consume 1.5-3 liters of vinegar, closed fumigation 0.5-2 hours to disinfect.
But Yu Kang, director of nutrition department at Beijing Concord Hospital, said acetic acid does have disinfection and sterilization at a certain concentration, but the effect is not very good, even if the concentration is very high, it is not recommended to use.
2, ViC bubble tablets: drinking ViC can improve immunity?
Discovering that VC is about eighty or ninety years old, VC discoverer A. Sente-Jorty won the 1937 Nobel Prize in Medicine. But Linus Bowling, who won the Nobel Prize for chemistry in 1954, linked VC to a cold.
The vitamin C controversy that beset by Bowling’s later years has led to the popularity of a large number of VC products, and he firmly believes that taking vitamin C in large quantities can make people healthier and live longer, treating a range of diseases including cardiovascular disease, cancer and the common cold.
But on his opposite side, there are more scientists who think over-replenishing VCs is useless or even harmful. For decades, there have been countless scientific research or medical personnel to carry out VC-related research work, can not prove the therapeutic effect of VC. Whether it is to supplement the vitamin C bubble tablets or a variety of fruits rich in vitamin C, in fact, are only antioxidant and to a certain extent to regulate immunity. Li Zhi, deputy director of respiratory medicine at Wangjing Hospital, once wrote that it was inappropriate to expect ViC tablets to fight the disease.
Wang Linrun, deputy director of the Department of Pharmacy at Zhejiang University, said that vitamin C bubble tablets do have the effect of ‘strengthening the body’s resistance’
After taking, the body’s resistance suddenly increases the stress response, to a certain extent can resist the invasion of the virus. But in fact, people infected with the virus will also produce antibodies against the invasion of the virus. Therefore, whether vitamin C can prevent disease is not directly proven.
3, smoking to prevent infection: fumes can form a protective layer?
Today, a picture claiming that “smoking can prevent viral infections” went viral on social platforms. The figure shows that “few smokers in the country have died as a result of SARS” and that “smoke and oil can block the attachment and entry of the virus, breaking the fundamental.” “
It is reported that this is a rumor that has been popular since the SARS period, when in order to dispel rumors, the Hong Kong health department specifically explained.
First, smoking not only does not prevent SARS infection, but also reduces the body’s resistance and increases the chance of infection;
Therefore, it is not possible to put a medical treatment in a hurry.
