How can bacteria spread from person-to-person?
Bacteria can easily spread from person-to-person in close contact settings such as daycare centres. 1
Children can transmit bacteria via aerosol, droplets, or direct contact with respiratory secretions of someone carrying the bacteria. 2 3
If these bacteria infect the middle ear, they can cause acute otitis media. 4
