What is influenza

Speaking of influenza, I believe many people know about it, or some people have actually had the influenza themselves. So what is influenza? The so-called influenza actually refers to the common cold. The incidence and transmission rate of influenza are very high. In addition, there are many media for the transmission of influenza, which is also a very important reason why many people are prone to influenza. There are many causes of influenza, but most cases are caused by viral infections.

Influenza is a common physical illness among humans. People who are usually infected with influenza usually have symptoms such as fever, runny nose, nasal congestion, and headache. In many cases, doctors judge whether they have influenza based on these influenza symptoms. In fact, there are many treatments for influenza in current medicine, so our influenza patients generally do not need to worry too much.

Influenza (flu for short) is an acute respiratory infection caused by influenza virus. It is also a highly contagious and rapidly spreading disease. It is mainly transmitted through droplets in the air, contact between people or contact with contaminated objects. Typical clinical symptoms are: sudden onset of high fever, body pain, significant fatigue and mild respiratory symptoms. Generally, autumn and winter are the peak seasons for the disease, and the complications and deaths it causes are very serious. The disease is caused by influenza virus, which can be divided into three types: A, B, and C. Type A virus often undergoes antigenic mutations, is highly contagious, spreads rapidly, and is very likely to become a large-scale epidemic. Influenza A H1N1 is a type A virus. The disease is self-limiting, but infants, the elderly, and patients with underlying cardiopulmonary diseases are prone to serious complications such as pneumonia, which can lead to death.

It is caused by influenza virus, which is not heat-resistant and can be inactivated at 100°C for 1 minute or 56°C for 30 minutes. It is sensitive to common disinfectants (1% formaldehyde, peracetic acid, chlorine-containing disinfectants, etc.) and ultraviolet rays, but is resistant to low temperature and drying, and can survive in vacuum drying or below -20°C. Among them, influenza A virus often undergoes antigenic mutations, is highly contagious, spreads rapidly, and is very likely to cause large-scale epidemics.

Through the detailed introduction in the above article, we also know the true definition of influenza. Influenza is actually a disease caused by an acute respiratory infection, and in many cases, influenza is extremely harmful to the human body. Sometimes, if it is not treated in time, it can be life-threatening. Therefore, we all must pay attention to this aspect in our future life.
