flu流感用英语怎么说

Flu (influenza) is a respiratory illness caused by viruses that infect the nose, throat, and sometimes the lungs. It is usually spread through the air by coughing, sneezing, or talking, or by touching a surface or object contaminated with the virus. Flu can cause mild to severe illness, and at times can lead to death.
There are three types of influenza viruses: A, B, and C. Influenza A viruses are the most common and can infect humans, birds, and some animals. Influenza B viruses primarily infect humans, while influenza C viruses primarily infect humans and pigs. Influenza A viruses are further divided into subtypes based on the combination of two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N). There are 18 different H subtypes and 11 different N subtypes.
Flu is most common in the winter months, but it can occur at any time of year. Flu vaccines are available to help protect against influenza infection. It is recommended that people get a flu vaccine every year, especially those who are at high risk of developing serious complications from flu, such as young children, older adults, and people with certain medical conditions.
