Summer influenza, beware of the child's "recruitment"

This year's influenza is "fierce" compared to the same period of previous years. At present, the overall level of influenza in the southern provinces (Guangdong, Fujian, Guangxi, etc.) is close to or even exceeds the winter peak of the previous season, and some provinces have entered a high incidence in summer. Seeing the number of influenza suddenly rising in the southern province, many parents expressed their concerns: "Will my baby be recruited?" "How to prevent flu?"

Why is the influenza virus active in the south?

Unlike ordinary colds, influenza is an acute respiratory infectious disease caused by influenza virus, often suddenly outbreak and rapid spread. The occurrence of influenza has a certain seasonality. In northern my country, influenza outbreaks are mainly winter and spring. However, in the south, due to the effects of temperature and humidity, summer and winter and spring are high incidence of influenza.

Human infection of influenza viruses can be divided into three types: A (A), B (B), and C (C). H3N2 subtypes in type A influenza are one of the most common virus types that cause seasonal influenza. Its contagious and pathogenicity are strong, which can easily lead to high intensity and large -scale popularity.

The recent Wuhan, Changsha, Guangzhou and other places, the climate is hot, humid, and some viruses are active, while some children have decreased activity, and they stay in the air -conditioned room all day. The immunity decreases. If the virus is infected, it is easy to get sick. Recently, our hospital has received a lot of children who have a cold and fever.

Of course, use air conditioning。 to get sick. Parents are advised to use the air conditioner reasonably, the room is ventilated regularly, and the indoor temperature is above 26 degrees Celsius to urge children to perform an appropriate outdoor exercise. These are good for children's health.

Which children who influenza loves "bullying"

Fluent is not a "large" cold, and its lethality is much stronger than a cold. Data show that there are 3 million to 5 million severe influenza in the world, and the mortality rate of severe influenza cases can be as high as 10%. Specific to children, about 20%of children infected with seasonal influenza each year. In other words, about one of about every 5 children suffer from flu. Among them, the infection rate of children aged 5 to 9 is the highest.

In particular, it is reminded that after the child under 5 years old is infected with influenza, the risk of severe illnesses is higher, and it is one of the main people in influenza -related hospitalization and death.

Therefore, if the child has the following symptoms, parents must be alert to the flu:

1. Higher fever, usually burning for 3 to 5 days, and the body temperature can be as high as 39 to 40 degrees Celsius. There may be symptoms such as fear of cold, cold war, cold hands and feet, and headache.

2. Sore throat baby may show crying and refuse to eat.

3. Cough is often dry cough, without obvious sputum.

4. Vomiting, diarrhea and other uncomfortable children may experience digestive symptoms such as vomiting, diarrhea.

5. Children with severe illnesses will have symptoms such as slow response, drowsiness, and dyspnea.

The above symptoms may appear on children with influenza, but may not necessarily appear at the same time. If the child does not fever (more than 3 days), the mental is sluggish, the muscle soreness, or no fever, but a severe cough, severe vomiting and diarrhea, and poor mental spirit, be sure to seek medical treatment in time.

Vaccination vaccine is very important

So, how can you protect your children from being threatened by influenza?

Vaccination of flu vaccines is the most economical and effective means to prevent influenza virus infection, which can significantly reduce the risk of inoculating the influenza and severe complications. Those who are older and more age can be vaccinated before the influenza season each year. According to the "Technical Guidance for Prevention of Chinese Popular Cold Vaccine Prevention", the flu vaccine vaccine 1 to 2 months before the peak of influenza epidemic can better play the protection of the vaccine.

Therefore, September to October each year is the best time to vaccinate. If it is not inoculated in time in time, the entire influenza epidemic season can also be vaccinated. No matter when the child is vaccinated, it is better than the vaccination.

Some parents will ask, why do influenza vaccines take vaccination every year?

This is because after the flu vaccine, the antibody level produced by the human body will gradually decrease after 6 to 8 months. In addition, influenza virus is easy to mutate. This year's influenza virus may be version 1.0, and next year may be upgraded to version 2.0. The annual influenza vaccine predicts possible virus strains based on previous epidemic conditions. Therefore, the annual virus strains are not necessarily the same, and serum types are also different.

Parents may also ask: "The vaccination is a‘ golden bell cover ’. Do n’t worry about influenza again?” In fact, this is not right. Influenza vaccines are not effective for preventing ordinary colds and do not guarantee 100%of flu. But as the most effective prevention method, the risk of influenza can be greatly reduced. Even if the "recruitment" can be reduced, it can reduce the symptoms of patients after illness and the probability of severe illness.

Don't forget these protection measures

In addition to vaccination, maintaining good personal hygiene habits is an important means to prevent influenza infectious diseases. The main measures include:

1. Wash your hands frequently, keep the environment clean and ventilated: Ensure that the number of ventilations is more than 3 times a day, and each time is not less than 15 minutes. Pay attention to indoor and outdoor temperature differences when opening the window.

2. Do not tie up: In the influenza popular season, try to reduce the activities of crowded places and avoid contact with patients with respiratory tract infections.

3. Enhance immunity: balanced diet, moderate exercise, sufficient rest.

4. Keep good respiratory habits: cough or sneezing, cover your mouth or nose with upper arms or paper towels, towels, and wash your hands after coughing or sneezing, try to avoid touching your eyes, nose or mouth.

5. Seek medical treatment in time: When you find that there are symptoms of influenza, you should seek medical treatment as soon as possible, especially children, seniors and patients with chronic diseases.In short, let children exercise more, improve disease resistance, and protect them at the same time.If the child is not sick or guilty, parents will be relieved.
