Influenza, also known as the flu, is an acute respiratory infection caused by an influenza virus that is prone to mutations. It is highly infectious and harmful. One of the greatest characteristics of the influenza virus is that it mutates every year, so that antibodies in the human body cannot effectively provide protection. Therefore, the previous year suffered from the flu and may be reinfected the next year. The flu itself is not a serious illness. It is not terrible. It usually recovers in about a week. In the spring, bacterial and viral transmissions are extremely rapid, and infant flu is always one of the most common diseases in the spring. Children who become infected with the flu are prone to complications such as pneumonia, otitis media, and myocarditis, posing a threat to the child’s health. The onset of flu is acute. The incubation period is usually 1 to 2 days, and then suddenly high fever occurs. The body temperature can reach 39°C to 40°C. At the same time, it is also accompanied by chills, usually lasting 2 to 3 days. In the case of flu, systemic symptoms are heavier. Symptoms such as fatigue, headache, dizziness, and body aches can persist for a period of 1 to 2 weeks after a long duration, normal body temperature, and fatigue. Relatively speaking, the flu has relatively minor respiratory symptoms, sore throat, a few stuffy noses, runny nose, etc. Some people may also experience gastrointestinal symptoms such as nausea, vomiting, loss of appetite, diarrhea, and abdominal pain. Influenza patients and latent infections are the main source of infection of the flu. They are usually contagious from 1 to 7 days after the onset of the disease and are the most contagious during the first 2 to 3 days. There are two main types of transmission of influenza: one is through airborne droplets. When flu patients talk, cough or sneeze, they will release the virus into the air. The virus can survive in the air for half an hour. Inhalation of tiny droplets containing the virus can be infected. The other is through contact. For example, the flu patient touches his nose and touches the doorknob or toy. When the child comes into contact with these things, he touches his nose, eyes and may also be infected. Especially in kindergartens, schools and other densely populated places, children may inadvertently contract flu. Daily life, level 10 prevention 1.
