The flu has entered a high incidence period, and these prevention and control knowledge should be known.

　　At the beginning of November, with the increase of temperature difference between day and night, many places entered the period of high incidence of influenza. What is the overall situation of influenza in China at present? How can we prevent the flu in our daily life?

　　Influenza, referred to as "flu" for short, is an acute respiratory infectious disease caused by influenza virus. The incubation period after infection is generally 1 to 4 days, with an average of 2 days. The clinical manifestations are generally sudden high fever, cough and sore throat. Some infected people may have complications such as pneumonia, myocarditis and otitis media. Experts said that at present, the overall influenza activity in China is still at a low level. However, since September, influenza activities in some provinces in China have shown an upward trend. It is expected that many places will gradually enter the flu season, and there will be a peak of influenza epidemic in autumn and winter.

Wang Dayan: Influenza mainly occurs in crowded places such as schools, child care institutions and old-age care institutions, so we should pay attention to preparing for prevention and control in advance.

　　According to experts, vaccination is one of the most effective measures to prevent influenza, which can significantly reduce the risk of influenza virus infection and serious complications. Every year, based on the global influenza surveillance results, the World Health Organization puts forward the recommended components of trivalent and tetravalent influenza vaccines for the next epidemic season, and residents can voluntarily vaccinate any influenza vaccine.

　　Researcher, Infectious Diseases Management Office, China CDC.
Peng Zhibin: We are going to get the flu vaccine. At the same time, we should also strengthen personal protection, such as wearing masks, regular ventilation, regular diet, regular work and rest, and our hand hygiene.

　　According to the data of the World Health Organization, worldwide, influenza can infect about 5% ~ 10% of adults and 20% ~ 30% of children every year, and cause as many as 5 million severe cases and 650,000 deaths. Susceptible groups of influenza include children under 5 years old, elderly people aged 65 and over, pregnant women, etc. The proportion of serious complications and deaths after these people are infected with influenza is relatively high. We should be alert to the trend of severe illness and seek medical advice in time if necessary.

Gang Liu: After the same pathogen infection, the severity depends on the amount of virus pathogen, early intervention and other comprehensive factors. Therefore, we advocate seeing a doctor as soon as possible and carrying out corresponding drug treatment as soon as possible. In principle, antiviral treatment should be as soon as possible, within 48 hours.

　　What’s the difference between influenza and mycoplasma pneumonia?

　　In addition to influenza, respiratory symptoms caused by mycoplasma pneumoniae infection have also appeared frequently in various places since autumn. Experts remind that mycoplasma pneumonia and influenza are two different respiratory diseases, so we should be alert to the overlapping risk of influenza and mycoplasma pneumonia.

　　In the past two months, the internal medicine clinic of Beijing Children’s Hospital has been running at a high level, and children are mainly infected with mycoplasma pneumoniae and influenza. What’s the difference between influenza and mycoplasma pneumonia?

　　Deputy Director of the National Center for Clinical Medical Research of Respiratory Diseases Director of the Department of Respiratory Medicine, Beijing Children’s Hospital
Xu Baoping: The common point of influenza and mycoplasma is respiratory tract infection, so there are symptoms of fever and cough, but the whole body symptoms of influenza are more serious, such as high fever, and the progress is relatively fast, as well as fatigue, headache and muscle aches. With the course of mycoplasma infection, patients with mycoplasma pneumonia will have severe and irritating dry cough, which is different from influenza.

　　According to the doctor, serum antibody detection and nucleic acid detection are effective means to diagnose mycoplasma pneumonia. Recently, there are many patients complicated with infection, which need to be diagnosed and differentiated by doctors, and it is forbidden to use drugs blindly.

　　Director, Department of Respiratory and Critical Care Medicine, East Campus of Jinan Central Hospital
Xin Wang: When taking medicine, you must follow the doctor’s advice or instructions, and don’t rush to achieve success. Overtaking one drug or using multiple drugs together may cause damage to other organs.
