1. What is influenza caused by?
Influenza is an acute respiratory infectious disease that is caused by influenza virus infection and is more harmful to humans.
Influenza viruses are divided into four types according to their core proteins: A (type A), B (type B), C (type C) and D (type D). Influenza A is an acute respiratory infectious disease caused by influenza A virus.
The main influenza viruses circulating in the population include: A H1N1 subtype, A H3N2 subtype, B Yamagata strain, and B Victoria strain influenza virus, whose antigenicity is variable and spreads rapidly, causing seasonal epidemics every year.
2. How does influenza spread?
Influenza patients and asymptomatic infected persons are the main sources of infection for seasonal influenza, which is mainly transmitted through the droplets of their respiratory secretions, and can also be transmitted through direct or indirect contact with mucous membranes such as the mouth, nasal cavity, and eyes.
Contact with items contaminated by the virus can also be infected through the above-mentioned routes.
In crowded and closed or poorly ventilated rooms, it can also be transmitted in the form of aerosols.
3. Now many parents of students report that their children have influenza A. What is the situation of influenza A in Sichuan recently?
In the past week, the positive rate of influenza virus detection in the southern and northern provinces of my country continued to rise, and the specific types were mainly influenza A (H1N1) and influenza A (H3N2) co-circulation.
Surveillance data in our province show that the number of influenza cases and the number of detected influenza positive samples have shown an obvious growth trend in the past two weeks, which is also characterized by the prevalence of influenza A (H1N1) and the co-circulation of influenza A (H3N2).
4. How to judge that the child has influenza A? What is the difference between influenza A and common cold and new crown?
The peak of influenza is generally in winter and early spring. After infection, the main manifestation is fever, with a body temperature of 39-40 ℃, which may be accompanied by chills and shivering. Older children are often accompanied by headaches and muscle aches all over the body. Some children have gastrointestinal symptoms. Symptoms, such as vomiting or diarrhea.
Influenza has different pathogens and clinical manifestations from common cold and new crown infection. After suffering from influenza, the main symptoms are fever, muscle aches and other systemic symptoms, while fever is rare after a common cold. The main respiratory symptoms such as cough, runny nose, sneezing and catarrhal symptoms are more obvious, and the symptoms of muscle aches all over the body are relatively mild. .
Except for mild and asymptomatic cases, the cases of new coronavirus infection are roughly the same as those of influenza. The difference is that the systemic symptoms of influenza virus will be more serious, and the symptoms of the upper respiratory tract of new coronavirus are more serious. At present, the number of visits to fever clinics in the province has increased, and the percentage of influenza-like cases has also increased, but the positive rate of the new crown test has continued to decline, only about 1%. Therefore, if you have symptoms such as fever and cough recently, you are more likely to have influenza. Antigen testing to confirm.
5. Can I go to school with a sickness if I have influenza A?
Students who have flu-like symptoms at school need to notify their parents in time to take them to a regular medical institution for diagnosis and treatment. Classes can only resume after 48 hours after their body temperature returns to normal and other flu-like symptoms disappear. Students should pay attention to self-isolation and go to school without illness. It is recommended to treat and rest at home.
6. How can parents prevent their children from getting influenza A?
Influenza vaccination is the most economical and effective way to prevent influenza. It can significantly reduce the risk of flu and serious complications for the vaccinated. If someone in the family is infected with the flu, it is recommended to isolate at home as much as possible, especially to reduce contact with children and the elderly. For children who cannot be vaccinated within 6 months of age, family vaccination can reduce childhood infections.
Avoid crowded places. During the influenza epidemic, try to avoid contact with patients with respiratory tract infections. When you go to crowded places, you must wear a mask.
Ventilate the room frequently. It is recommended to open the windows at least twice a day for no less than 30 minutes each time. When the air is dry, you can properly use a humidifier at home to keep the indoor air at a certain humidity.
Maintain good personal hygiene habits, pay attention to appropriately increase or decrease clothing according to temperature changes, eat a balanced diet, exercise appropriately, work and rest regularly, and enhance immunity.
If your child develops flu-like symptoms such as fever and cough, it is recommended not to go to class temporarily to avoid cross-infection and seek professional medical treatment as soon as possible.
7. What should be done when a family member is infected with influenza?
If a family member is infected with the flu, please pay attention to the following measures:
(1) Wear a mask. Patients and family members should wear masks when they are in close contact. When the mask is dirty, deformed, damaged, or smelly, it needs to be replaced in time.
(2) Pay attention to hygiene. Cover your mouth and nose with a tissue or sleeve when sneezing or coughing. After touching the patient or the respiratory secretions of the patient, or after handling the items used by the patient, wash your hands with soap, soap or hand sanitizer or use a disinfectant to disinfect your hands.
(3) Enhance ventilation. When the patient is at home, it is necessary to strengthen the ventilation of the room and pay attention to environmental hygiene.
(4) Pay attention to the condition. Closely observe the changes in the patient's condition, and seek medical treatment in time if persistent high fever, dyspnea, severe vomiting, etc. occur.
(5) Childproof. Minimize extracurricular offline training in the near future. If you must participate, you should take personal protective measures or keep a distance from symptomatic children.
(6) Rest at home. Influenza patients should rest at home according to the doctor's advice, and do not go to school or work for the time being.
