Is the respiratory system first to be affected by harmful bacteria from sneeze?

Yes, the respiratory system is typically the first to be affected by harmful bacteria expelled during a sneeze. When an infected person sneezes, they release droplets containing bacteria into the air, which can be inhaled by others. This can lead to infections in the upper or lower respiratory tract, such as bronchitis or pneumonia. Prompt exposure can compromise respiratory health, especially in individuals with weakened immune systems.
