At present, many places across the country have entered a period of high incidence of respiratory infectious diseases, and the number of children infected has increased, and news about "fever" has also been on the hot search many times.
Is the flu more "vicious" than in previous years?
Authoritative voice: No, don't panic!
This wave of influenza caught many parents off guard. Many parents began to be anxious: is this year's flu more "fierce" than in previous years?
At present, respiratory infections have entered the high incidence season, and hospitals in many places have seen a "wave of medical treatments" for respiratory diseases. Recently, the number of fever clinics in many hospitals in Hangzhou has surged, and some hospitals have even increased tenfold, especially in pediatric outpatient clinics, where patients with influenza A account for the majority.
Jin Dongyan, a professor at the School of Biomedical Sciences of the Li Ka Shing Faculty of Medicine of the University of Hong Kong, once gave the answer in an interview with **: The H3N2 influenza virus in this epidemic itself is more pathogenic, and children are more susceptible to infection than **.
But judging by the data,The severity of the epidemic did not exceed the level of the peak in 2017 and 2018Judging from the total number of infected people, infection symptoms and other data,It is impossible to say that it is "worse than before the pandemic", and there is no such thing as "the virus is stronger than before the pandemic".
Judging from the trend of the influenza pandemic, this year is only the time of the outbreak earlier, and the data is basically the same as the same period before the epidemic. Jiang Chunming, director of the Department of Pediatrics of Hangzhou First People's Hospital, saidWinter is traditionally the season for flu, so parents don't need to panic too muchIt should be treated scientifically and rationally.
The number of flu people has not exceeded that of March.
No new infectious diseases caused by new viruses or bacteria have been identified
Wang Dayan, director of the National Influenza Center of the Institute of Viral Diseases of the Chinese Center for Disease Control and Prevention, said that compared with last winter, the main circulating influenza A (H3N2) subtype viruses and influenza B viruses have not changed, and they are also consistent with the main branches circulating in most parts of the world. The influenza epidemic season in winter and spring in various parts of China is generally from mid-to-late October to mid-to-early March of the following year, "generally peaking around January." ”

Wang Yingshuo, director of the outpatient office, director of the Department of Pediatrics, and deputy director of the Department of Respiratory Medicine of the Children's Hospital of Zhejiang University School of Medicine, believesAlthough the number of infections is rising, it does not seem to have surpassed the peak of the flu wave in March.
There is a key piece of data to refer to
During the influenza epidemic in March, when the epidemic peaked, there were influenza-like cases in fever clinicsThe positive detection rate of influenza virus once reached more than 90%, "the current number is around 45%, and it should not continue to rise in the future."If other strains of influenza are circulating at the same time, there may be an increase in the number of sick people. Wang Yingshuo said that in previous years, the peak of influenza generally appeared in late December and early January, but this year, with the advance of the influenza epidemic time, the peak has also been advanced. As the weather gets colder, infections with other respiratory viruses such as respiratory syncytial virus may also increaseThere is also a risk of a resurgence of the coronavirus.
In addition to children, other high-risk groups such as the elderly, people with underlying medical conditions, and people with weakened immune systems are also of concern.
When will the peak come?
Jin Dongyan, a professor at the School of Biomedical Sciences of the Li Ka Shing Faculty of Medicine at the University of Hong Kong, pointed out that according to the statistics of cases with influenza-like symptoms released by the National Influenza Centre, the north is currently at a high level of seasonal influenza, while the epidemic curve in the south has just climbed from the low level.
"It is expected that the North may peak in a few weeks, and the South may not peak in a month or more. ”Jin Dongyan said.
Wearing masks, washing hands frequently, and ventilating frequently are very effective in preventing the spread of respiratory diseases. We should do a good job of personal protection, do not go to work with illness, do not go to school with illness, and adhere to good personal hygiene Xi and a healthy lifestyle. It is advisable to get vaccinated against the flu as early as possibleWang Dayan introduced that among the currently popular respiratory diseases, influenza, new crown, and pneumococcal infection have corresponding types of vaccinesThe flu vaccine has been used in our country for decadesScientific research and inoculation practice have been well provenThe flu vaccine is safe, effective, and a well-established vaccine. Getting a flu vaccine can effectively reduce infection, and even if you are infected, you can reduce the incidence of illness, and even if you get sick, you can reduce the severity of the disease. At present, it is the high incidence season of influenzaThe flu vaccine is still effective for people who have not received the flu vaccine beforeIt is recommended that everyone get vaccinated against the flu as soon as possible. Here, it is particularly pointed out that people over 6 months old can receive influenza vaccine, especially for high-risk groups such as children, the elderly, and patients with chronic diseases, who are at higher risk of severe disease after being infected with influenza, and influenza vaccination can effectively reduce the risk of developing severe disease and death. ** Ningbo Evening News, 21st Century Business Herald
