According to the report of the World Health Organization, influenza can cause 5% - 10% of adults and 20% - 30% of children to get sick every year, and there are about 1 billion people infected with influenza in the world. Influenza is a kind of self limited disease, most of which are mild, with 3-5 million severe cases and 290000-650000 deaths.

But influenza is different. Most of influenza is related to the close contact with the surrounding environment. Influenza patients have severe systemic symptoms and mild local symptoms. The whole body symptoms are fever. Some patients have high fever, over 39 degrees. They will also have muscle ache, poor appetite and other symptoms.

Because of the strong seasonality of influenza, the influenza vaccine is not effective at all times. Only in the influenza epidemic season, the antibody effect of the vaccine is the strongest. He suggested that the elderly, children, patients with chronic diseases and medical staff should be vaccinated and prevented in time.

Vaccination is one of the most economical, fundamental and effective means of prevention. Influenza vaccine belongs to non immunization program vaccine, which is inoculated by residents voluntarily and at their own expense.

People often say that the cold, mainly in the body rain, fatigue, cold and other low resistance, comes from their own pathogens, such as coronavirus.

From October to march of the next year, there is an epidemic season of respiratory infectious diseases such as influenza. Influenza is an acute respiratory infectious disease caused by influenza virus. People are generally susceptible to influenza virus, which is prevalent all over the world every year.

The national health and health commission established the national influenza medical treatment expert group, further improved the diagnosis and treatment plan, prepared the training manual for influenza medical personnel, and provided technical support for influenza medical treatment.

The influenza pandemic has plagued the whole history of mankind. As early as 412 BC, Hippocrates, the father of modern medicine in ancient Greece, recorded flu like symptoms. But it was not until 1580 that there was a clear record of a pandemic. Influenza outbreaks are characterized by periodicity, usually once in 20 or 30 years. It can be said that human beings live with influenza virus.

We plan to supply 28 million doses of influenza vaccine this year, and 17 million doses of influenza vaccine have been supplied, three times the supply in the same period last year. The cumulative number of vaccinations this year has exceeded 8 million, twice the same period last year.

Recently, the National Health Commission issued the work plan for influenza prevention and control in the 2019-2020 epidemic season, and proposed 15 key measures. Among them, there are three measures related to biological vaccine, including defining the key population for influenza vaccination, optimizing vaccination services, and strengthening the research on relevant vaccine policies. At the same time, it also includes several "social vaccine" measures, such as promoting healthy lifestyle, developing good health habits, avoiding crowded places in epidemic season, wearing masks when sick and going out, resting at home with minor illness, and self isolation, to comprehensively carry out comprehensive prevention and control of influenza.

In 1918, the most devastating "Spanish influenza" pandemic. Influenza causes 20 to 40 percent of the world's population to be infected, with 20 to 50 million deaths worldwide, far more devastating than the first World War.

This pandemic, known as the "global century plague", brings people terror, but also brings great changes in American medical research and even the whole field of natural science. Scientists conducted the world's first human trial, and tried to prepare serum and vaccine, which ended in failure. "Don't talk about medicine, it's going to conquer disease," said one doctor From 1957 to 1958, the first outbreak of global influenza occurred in Guizhou, China, with more than 3 million deaths. Ten years later, a flu outbreak in Hong Kong killed 1.5 million people around the world.

In general, the mortality of influenza is less than 1%, which can be relieved in a week or so, but it can not be ignored. When people get flu, they should find it, diagnose it and treat it early.

In addition, we will strengthen personnel allocation and antiviral drug storage; especially, we will strengthen medical treatment for the elderly, children, pregnant women, people with basic diseases and other high-risk groups of influenza; we will actively treat the primary disease, prevent complications, minimize severe cases and reduce mortality.

Now, China is about to enter the influenza epidemic season, and will gradually enter the influenza peak season after December.

Every experience of fighting against influenza is used in the next "battle"; every time the flu strikes, human beings are faced with new fears and challenges. Because influenza virus is easy to mutate and difficult to predict, the epidemic situation will change every year. The prevention and control work is long-term, complex and arduous.

According to Gao Zhancheng, director of the respiratory and critical care department of the people's Hospital of Peking University and member of the national influenza medical treatment group, there are differences between influenza and cold
