Influenza can cause various serious complications
Chief physician of the Department of Respiratory Medicine, the First Affiliated Hospital of Henan University of Traditional Chinese Medicine, introduced that influenza is an acute respiratory disease caused by influenza virus, and is characterized by strong infectiousness and rapid transmission.
The main source of influenza is influenza patients and hidden infections, and it will be contagious from the end of the incubation period to the acute onset.
Liang Shijie, director of the Infectious Disease Prevention and Control Institute of Zhengzhou Center for Disease Control and Prevention, introduced that in terms of infection, the influenza virus mainly spreads through droplets such as sneezing and coughing, but it can also be directly or indirectly transmitted through mucosa such as the mouth, nose, eyes, etc., and it can also cause infection after contacting items contaminated by the virus.
Influenza virus directly invades the human respiratory system, causing many life-threatening complications such as viral pneumonia , secondary bacterial pneumonia , acute respiratory distress syndrome, shock , diffuse intravascular coagulation and other serious life-threatening complications.
Influenza virus will appear in a new look every winter, causing a seasonal epidemic.
Influenza symptoms lack specificity and is not easy to distinguish
Influenza symptoms are the main basis for routine clinical diagnosis and treatment.
Liang Shijie introduced that influenza is generally acute onset, manifested as fever (some cases may experience high fever, body temperature up to 39℃~40℃), cough, sore throat, runny nose, nasal congestion, body pain, chills, fatigue, diarrhea, vomiting and other symptoms.
However, these symptoms lack specificity. Many people tend to regard it as a common cold and other upper respiratory tract infections after they get sick, thus delaying treatment.
" To determine whether you have influenza, you will eventually rely on laboratory diagnosis of . At present, the detection methods mainly include viral nucleic acid testing, virus isolation and culture, antigen testing and serological testing." Liang Shijie told reporters that in terms of influenza treatment, those with milder conditions can go home and take medication after visiting the doctor, while those with severe conditions need to be hospitalized for treatment.
In order to avoid spreading the flu to family members, patients with influenza should avoid close contact with family members after returning home. They should be in an independent space at home and try to live alone in a house.
Daily necessities should also be separated from other family members, and can be boiled for more than 30 minutes or disinfected with ethanol, iodine, iodine tincture and other disinfectants. The room should be kept ventilated. In addition, try to avoid going to public places.
"If you are in the fever period, you must reduce the fever in time, take a full rest in , drink more water appropriately, and eat easily and nutritious. " Liang Shijie reminds that if you continue to have high fever, heavy breathing, or suddenly appear new symptoms, such as poor mental state, frequent vomiting or diarrhea, you should seek medical treatment in time.
Influenza "prevention" is greater than "treatment"
Li Feng, director of the Immunization Planning Institute of Zhengzhou Center for Disease Control and Prevention, said that influenza is self-limiting, but some patients will experience complications such as pneumonia and then develop into severe influenza. A few severe cases are progressing rapidly. In severe cases, they may die from multiple organ failure due to acute respiratory distress syndrome (ARDS).
In his opinion, in the face of influenza, "prevention" is greater than "treatment", and getting influenza vaccination is the most effective way to prevent influenza at present.
Li Feng also mentioned that in order to ensure immune protection before the high incidence of influenza season, it is best to get vaccinated 1 to 2 months before the influenza season.
Flu prevention Experts "Prevention and Treatment Tips"
Li Feng reminds that in addition to getting influenza vaccine, drugs can also be used to prevent it.
Although vaccination is the best way to prevent influenza, there are some special circumstances when influenza outbreaks. If there are contraindications for influenza vaccination or high-risk children who do not achieve the best immunization effect within 2 weeks of vaccination, can be urgently and temporarily prevented by taking medication after contacting influenza patients.
"It is particularly important to note that drug prevention must be carried out under the guidance of a doctor." Li Feng said.
Preventing influenza also requires starting from the aspects of living habits:
wash your hands frequently, use soap or hand sanitizer to wash your hands with running water;
Keep the environment clean and ventilate indoors, reduce crowds, and wear a mask when going out;
When coughing or sneezing, cover your mouth and nose with tissues, towels, etc.;
When you go out, try to avoid touching your eyes, nose and mouth with your hands;
Strengthen exercise and improve immunity; you should rest at home and seek medical treatment as soon as possible when you have respiratory symptoms.
