Influenza can be self-isolated, especially if there are immunocompromised people in the home. Influenza is caused by infection with the influenza virus and is generally highly transmissible, spreading through the respiratory tract. Therefore, if you are infected with influenza, you should theoretically be quarantined. However, since influenza is more common, especially in winter and spring, and has a better prognosis, self-isolation is the mainstay. However, if there are people with relatively low immunity at home, such as the elderly, children, people with underlying diseases, etc., isolation is recommended. Such people are susceptible to infection, and low immunity may lead to more severe symptoms after infection, affecting normal life and health.
