Not all household contacts will become infected. The risk of infection depends on various factors, such as the extent of exposure, viral load, and individual immunity. Preventive measures like ensuring good indoor ventilation, avoiding close contact with the infected person, frequent handwashing, and wearing masks can reduce the risk of infection. In addition, vaccination is an effective way to prevent influenza B. Therefore, individuals living with someone who has influenza B do not need to panic; taking appropriate precautions can significantly lower the risk of infection.
