According to statistics, the annual number of influenza cases worldwide is 600 million to 1.2 billion, among which 3-5 million cases of severe influenza and 250,000-500,000 deaths, and the morbidity and mortality rate of severe influenza can reach 8%. Recent foreign studies have shown that the likelihood of influenza-induced lung infection in people over 65 years of age is 1.25-2.28 per 1,000 people, and for those with chronic diseases, the likelihood of influenza-induced pneumonia is even greater at 4.76-6.36 per 1,000 people. Each year, approximately 100 million people in the Northern Hemisphere are affected by influenza. Influenza kills more than 20,000 people and hospitalizes more than 100,000 each year. Anyone can get the flu. However, the elderly, children and some people with chronic illnesses are more likely to suffer serious complications from the flu virus than younger, healthier people. Recent studies by the American Lung Association show that influenza and pneumonia are not only the 5th leading cause of death in the United States for people over the age of 65, but also the 6th leading cause of all deaths. Influenza is spread directly, mainly through droplets from patients’ coughs and sneezes, and is most contagious within three days of onset. The incubation period of influenza is short, about 1-2 days. If the symptoms are mild, only general discomfort is felt and lasts 1-2 days. If the symptoms are severe, the body temperature can reach 39-40 degrees Celsius with high fever, back pain, headache, and severe symptoms of systemic toxicity. Clinically, there are four types of influenza: 1. Simple type The most common type, the patient has fever, body temperature of 39-400C, dizziness, headache, nasal congestion, etc., which usually subsides gradually after 3-5 days. 2. Pneumonia type High fever does not subside, severe cough, shortness of breath, the condition can be extended to 3-4 weeks, and a few can lead to death. 3. In addition to systemic symptoms, gastrointestinal symptoms such as nausea, vomiting and diarrhea may be present. For personal health, the biggest danger of influenza is serious complications and complications leading to hospitalization or even death. Anyone infected with influenza can develop complications, but the elderly and children are at greater risk than healthy young adults. Common complications of influenza in children include pneumonia, myocarditis, bronchitis, otitis media, hyperthermia, meningitis, etc.; pneumonia is the most common complication of influenza in the elderly. Influenza can also induce recurrence and aggravation of chronic diseases, which can then lead to hospitalization or even death. It is well documented that influenza complicated by pneumonia is the 5th leading cause of death for diabetics in the United States and the 6th leading cause of death for all Americans. Influenza can vary greatly depending on the patient’s body type and the type of virus, and is even more complicated when it is complicated by other conditions. It is recommended that you seek prompt medical attention if you experience flu symptoms. When you have the flu, the body naturally limits the disease, i.e., you can recover without medication, but occasionally you may contract other diseases, such as sinusitis, otitis media or bronchitis. And influenza can seriously lead to life-threatening complications such as pneumonia, bronchitis, heart and lung disease, asthma, and congestive heart failure. If you get influenza, go to the hospital promptly and take rest. Influenza may lead to acute attacks of existing chronic diseases in the elderly, high fever may also cause convulsions and convulsions in children, and influenza may also combine with tracheobronchitis, otitis media, pneumonia, myocarditis and other diseases, which can seriously threaten patients’ lives. Therefore, the treatment of influenza should be mainly symptomatic, and those with high fever should have their fever reduced promptly, including cooling with drugs and physical methods. In case of combined bacterial infection, patients should use antibiotics reasonably under the guidance of doctors. If you have influenza, you can also take some Chinese medicines to clear the heat and detoxify the toxin, and you can also take some western medicines, such as amantadine or amantadine, etc. These medicines can shorten the course of influenza and at the same time can reduce the symptoms of influenza. In addition, influenza patients should rest in bed early, drink more water and prevent secondary infections. Influenza vaccination is the most important preventive measure. It is effective for healthy people and is also suitable for people who are prone to serious complications caused by influenza, including people over 65 years old, people taking immunosuppressive drugs, people with diabetes, and people with severe anemia.
