Since the winter, the flu has been widespread in the country. The popularity of the previous year has left many people with a lingering fear. Recently, the "flu" has once again become a hot topic in the streets.
What is the prevalence of influenza this season? Is it as terrible as I imagined? What are the misunderstandings of influenza prevention? The reporter will analyze for you one by one.
What is the current situation of the flu?
Ms. Peng, a working worker in Beijing, recently developed suspected flu symptoms such as high fever and continuous vomiting. She then went to a top three hospital for a fever clinic. "Registration, payment and blood collection are all in large groups, and there are many people who infusion." Ms. Peng said that many colleagues in the unit have successively "suggested".
The reporter's investigation found that the emergency department of the Children's Hospital was overcrowded, and the primary and secondary schools also became the hardest hit areas of the flu. Ms. Shi of Beijing told reporters that some time ago, many of her classmates had a flu in the class, so the class was suspended for 4 days. Later, other classes also had similar situations. The school had to cancel the New Year party.
Since the winter of last year, the flu has been widespread in the country. It seems that the flu is "what situation"?
"There are four types of influenza viruses: A, B, and B. In the population, the main causes of seasonal influenza are type A and type B." Li Zhongjie, a researcher at the Center for Infectious Disease Prevention and Control of the Chinese Center for Disease Control and Prevention, is in the country on the 25th. According to the monitoring report of the National Influenza Surveillance Network, the main epidemic is the H1N1 virus, which accounts for more than 90% of influenza A. No antigenic effects affecting the influenza epidemic this year have been found. Variety.
Lin Lin, director of the Department of Respiratory and Critical Care Medicine of Guangdong Provincial Hospital of Traditional Chinese Medicine, said that continuous high fever is a feature of this flu, often accompanied by cough, sore throat, pain in the body, sneezing and sneezing.
Lei Zhenglong, deputy director of the National Health and Health Commission's Disease Prevention and Control Bureau, said that the latest monitoring data show that China has entered the peak period of influenza activities, the upward trend of the southern provinces has slowed down, and the northern provinces are in the platform period.
"According to the comprehensive analysis of experts, the level of influenza activity in China's influenza epidemic season in 2018-2019 will be lower than that in the previous epidemic season." Lei Zhenglong said that with the winter vacation of schools and child care institutions, the influenza epidemic will gradually decrease. .
Is the flu really terrible?
The flu used to be less noticeable. In the winter and spring of 2017-2018, the influenza B sputum “brushed a sense of existence” and left a deep impression on people; and the online brush-screen article “Beijing Middle Age under the Influenza” made some people have the flu Fear.
Is the flu so terrible? According to disease control experts, seasonal flu is a common disease in the population and is a disease that is generally prevalent among people. People can develop acquired immunity after suffering from influenza, but the influenza virus will soon undergo antigenic variation to escape host immunity. Therefore, a person may infect the same and/or different types of influenza viruses multiple times in their lifetime.
Liu Qingquan, an expert from the National Influenza Medical Treatment Expert Group and dean of the Beijing Chinese Medicine Hospital, said that because the flu is highly contagious and the flu virus is volatile, different flu viruses will appear in different seasons and years.
Winter and spring are high seasons for infectious diseases such as influenza. Lei Zhenglong said that influenza is a common respiratory infection in winter and spring. Every winter and spring, there will be a peak of epidemic, but the length of time and peak value are different.
According to experts, after the general population has flu, more than 3-4 days after the onset of illness, the body temperature gradually subsides, and the systemic symptoms improve, but cough and physical recovery often take 1-2 weeks. People with severe high-risk factors are prone to complications after being infected with the flu, and may be life-threatening in severe cases.
"Children under the age of 5, especially under 2 years of age, elderly people over 65 years of age and chronic diseases such as chronic respiratory system, chronic diabetes and cardiovascular system have a higher risk of complications. Special attention should be paid to the prevention of influenza." Li Zhongjie said.
Why have many people around me recently "in the middle of the move"? Experts said that the winter weather is cold, the body's resistance to the virus is weakened, and people spend most of their time indoors. The windows are often closed, causing the air to circulate, and the virus is more likely to spread.
From the perspective of Chinese medicine, "this year, there is very little rainfall and snowfall in Beijing, and it is easier to form dry heat in the body, so it is easier to 'feel the evil of the cold.'" Zhang Wei, deputy director of the Department of Traditional Chinese Medicine of the Space Center Hospital, told reporters that although the northern winter is outdoor Extremely cold, but the indoor temperature is high, combined with high calorie diet, less physical activity, the body is prone to form heat. "There is a cold, and there is heat inside, which forms the pathological condition of 'cold fire.'"
According to Guo Yanhong, deputy director of the Medical and Health Administration of the National Health and Health Commission, in order to help medical staff and the public to properly respond to the flu, in 2018, the Health and Health Commission, the State Administration of Traditional Chinese Medicine, the China CDC and other departments successively issued flu prevention and control. , medical treatment, case outbreak epidemic disposal, influenza vaccine vaccination technology and other aspects of the document, and set up a national influenza medical treatment expert group, strengthen technical guidance, professional training, tracking and analysis of the incidence of the situation, timely judgment.
Error prevention "all white"
Mastering the correct prevention and control knowledge will enable the flu to “shun back and forth”, even if it is unfortunate, “Zhong Zhao” can calmly deal with it. However, the reporter found that despite the "baptism" of the flu in the previous year, people still have misunderstandings and lack of attention in prevention, so that the virus has a chance.
In crowded public places such as the subway, most people do not wear masks; family members do not wash their hands after touching items used by flu patients; high-risk groups such as the elderly, infants and children are reluctant to get flu shots…
“You should wear masks for flu patients and minimize contact with children.” Zhang Wei said that when taking care of flu patients, you should wear masks and wash your hands frequently. You should also open windows as much as possible to reduce indoor bacterial density and reduce air. Virus dust droplets.
Regarding the misunderstanding of vaccines, Zhang Wei said that flu vaccine is the most effective way to prevent influenza. Vaccines should be given 1-2 months before the flu season, and their protection is generally only 6-12 months, so injections are needed every year.
Chinese medicine experts believe that in addition to some common methods, wearing anti-epidemic sachets made of traditional Chinese medicine can also play a role in preventing influenza. In addition, traditional Chinese medicine foot bath, fumigation, massage and other external treatment methods can also enhance physical fitness.
Many people have failed to treat the flu. Experts say that early treatment and scientific standard treatment are the key, avoid abuse of antibiotics and infusion therapy.
"Once flu-like symptoms or confirmed flu, do not encourage sickness to work, must be isolated, if the condition is aggravated, it is necessary to seek medical advice." Li Zhongjie specifically stressed that this is a good protection for themselves and others.
