What is the cause of the flu and how is the flu caused

Influenza, the full name of epidemic ** risk. It is an acute respiratory infectious disease caused by influenza virus, and the pathogen is epidemic virus type A, B, and C. It is especially common in type A.

It is more common in winter and spring. The common cold, also known as an upper respiratory tract infection (commonly known as the cold), is one of the most common illnesses.

The flu virus is usually spread by droplets from sneezing or coughing. When a person has the flu, symptoms occur suddenly and worsen within a few hours, with a high fever and a body temperature of 39 or higher. Pain in the eyes, pain in the limbs, fatigue, sometimes conjunctival hyperemia, nasal congestion, runny nose, and sore throat.

Children often have digestive symptoms such as abdominal pain, bloating, diarrhea, vomiting, and even convulsions. The symptoms of influenza are even more life-threatening for infants, young children, the elderly and people with chronic diseases.

Western medicine prophylaxis.

Combination cold medicines containing antiviral ingredients can reduce the duration and severity of illness while relieving flu symptoms, and prophylactic medication during influenza epidemics can reduce the incidence of influenza.

Amantadine hydrochloride and amantadine hydrochloride have a preventive effect on influenza A. It can block the infection of viruses to the human body. Amantadine hydrochloride is effective in reducing the severity and incidence of symptoms caused by influenza by 70% to 90%.

The protection against influenza A is comparable to that of vaccines. Researchers have confirmed that influenza A can be prevented by taking it for 3 to 5 days during an influenza epidemic. If pregnant, infant, mentally ill or epileptic person, consult a physician before use.

Riboside, also known as virazole, has been shown in vitro to be anti-influenza A and anti-influenza B, but the clinical effect has not been confirmed. Recently, a class of neuraminidase inhibitors, such as 4-guanidine n-acetylneuraminic acid, can be anti-influenza A and anti-influenza B, and are currently in the stage of clinical application.

Influenza vaccination can prevent influenza to a certain extent, but it does not cover all strains of the virus, which affects the effectiveness of prevention. If you are pregnant or allergic to eggs, ask your medical professional if a flu shot is right for you.

15 grams of mugwort leaves, atractylodes atractylodes, and realgar are burned to disinfect the room with smoke, once a day, 3-5 times in a row.

Take 30 grams of wild chrysanthemum flowers, fry them in water and rinse them or spray them to moisten their throat.

Take 30 grams of large green leaves, banlan root, and guanzhong, decoction in water instead of tea, one dose a day.

Influenza is caused by influenza rocky ridge attack virus, which can be divided into three types: A(A), B (B), and C (C). A H1N1 is also a type of A type. The disease is self-limited, but in infants, young children, the elderly, and patients with underlying cardiopulmonary diseases, it is easy to develop serious complications such as pneumonia and lead to death.

Epidemic ** epidemic (referred to as influenza) is an acute respiratory infection caused by influenza virus, and it is also a highly contagious and fast-spreading disease. It is mainly transmitted through airborne droplets, person-to-person contact, or contact with contaminated items. Typical clinical symptoms are:

Sudden onset of high fever, generalized round pain, significant fatigue, and mild respiratory symptoms. Autumn and winter are the peak periods, and the complications and deaths caused are very serious.

Etiology. Influenza viruses are mostly transmitted by droplets, which can lead to infection.

The cause is usually tiredness, lack of rest, weak constitution, etc., and people who often go to crowded places are also susceptible to infection.

Pneumonia may occur in infants, young children, older adults, people with cardiopulmonary disease and other chronic diseases, or immunocompromised people.

There are three types of influenza viruses in humans: A, B, and C.

Among them, influenza A is prone to cause large-scale epidemics, type B can cause local epidemics, and type C can only cause sporadic cases.

Healthy Pathway. For influenza patients, early detection and early detection are crucial, mainly antiviral and symptomatic.

**During the period, patients should pay attention to rest, drink plenty of water, supplement vitamin C, and avoid spreading the virus to people around them.

At the same time, the effect will be better with medication.

Mainly, influenza virus mutations have created new subtypes. Influenza A viruses are divided into many subtypes based on neuraminidase and hemagglutinin, some of which do not infect humans. However, with the mutation of virus genes or the communication between ** and avian influenza, new influenza viruses have been produced that can infect humans.

The virus is generally unresistant in the population, creating a pandemic.

The population has extremely poor immunity to influenza viruses. Disease control efforts have not kept up.

The virus, mainly through the air, droplets, spreads.
