On January 4, 2019, the National Influenza Center released the monitoring. Many provinces and cities in China have entered the influenza epidemic season in winter and spring 2018-2019, with an upward trend. Let's not panic about the outbreak of influenza. Let's explain the causes and prevention methods of influenza!
What is the main reason for the increase in influenza patients? Seasonal and weather factors
For the reasons for the recent increase of influenza, experts believe that seasonal and weather factors are the main reasons, coupled with the decline of people's resistance and other comprehensive factors, which leads to the above situation.
"October of each year to march of the next year is the high incidence season of respiratory infectious diseases such as influenza." Li Feng, director of the Immunization Planning Institute of Zhengzhou CDC, said that affected by the climate, the winter and spring season itself is a high incidence season of influenza. In addition, due to the recent decline in temperature and dry air, the number of patients with upper respiratory tract infection has increased compared with some time ago.
Exploring the high incidence of respiratory infectious diseases in winter and spring, Li Feng said that in winter, people have less outdoor activities, go out by car, the doors and windows of home and office are closed, and everyone is in a closed space. Compared with summer and autumn, the air circulation conditions are very poor.
Influenza virus is mainly caused by sneezing, cough droplets scattered into the air, contact between people and contacts, and exposure to contaminated substances by influenza virus, which leads to influenza. Experts said that most respiratory infectious diseases, including influenza, have been spread by droplets. The closed space and dry air environment are more conducive to the spread of the virus.
"In addition, the elderly and children have weak resistance, which will also increase the risk of influenza."
Some questions about influenza
Question 1: won't you catch a cold after injecting influenza vaccine
There are two mistakes in this view. First, influenza vaccination can not completely eliminate the infection of influenza virus. Influenza may still occur when immunity is low, but people injected with influenza vaccine have a lower chance of suffering from influenza, and get better quickly after being infected with influenza virus. In addition, there are many pathogens that cause colds, and influenza virus is only one of them, Influenza vaccine has no preventive effect on infection by other pathogens.
Question 2: won't you get the flu again after getting the flu this year
Influenza virus is particularly susceptible to mutation. Although influenza virus can produce the corresponding immunity after infection, this immunity has no effect on the new variants of the virus, so it is possible to have influenza two times a year.
Question 3: can drinking more water treat influenza
Drinking water itself has no antiviral effect, but drinking water can supplement the loss of body water caused by fever, accelerate the blood circulation of the body, and increase the excretion of urine and toxins in the body. Therefore, it is helpful to alleviate the symptoms of influenza.
How to prevent influenza?
1. Try not to go to crowded places during the flu season
Most influenza epidemics occur in autumn and winter, but when influenza epidemics occur, try to avoid going to places with many people, because everyone's respiratory tract may be parasitic with some viruses and bacteria, and mutual contact may lead to mutual infection.
2. You'd better wear a mask when you go out
In the influenza season, wear masks as much as possible, especially when visiting densely populated places or visiting influenza patients. Wearing masks with dense grids is conducive to blocking the possibility of influenza virus inhalation and avoiding colds.
3. Early influenza vaccination
On the one hand, influenza vaccination can prevent the infection of influenza virus. On the other hand, if infected with influenza virus, it can shorten the course of disease and prevent the occurrence of severe influenza and influenza complications.
4. Wash your hands frequently
In addition to droplet infection, direct contact with influenza virus may also lead to infection. Frequent hand washing can effectively avoid the occurrence of cold. The more thorough hand washing is, the less likely influenza infection is.
5. Exercise frequently and drink plenty of water
Regular exercise can promote the blood circulation of the whole body, enhance the vitality of the immune system, improve the overall resistance of the body, and avoid the invasion of external pathogens. Drinking more water can speed up the discharge of toxins from the body, which is also helpful for immunity.
Finally, emphasize: symptomatic treatment, timely medical treatment!
With influenza, the symptoms are different and the treatment methods are different.
Experts say patients infected with influenza virus should not be careless. Pay attention to rest, drink plenty of water and supplement appropriate nutrition and vitamins. Start anti influenza drug treatment as soon as possible. If there are symptoms such as high fever, severe cough, dyspnea and blurred consciousness, get medical attention in time.
