It is possible to become infected with keratitis. Corneal inflammation is usually caused when the cornea is infected by pathogens such as viruses or bacteria due to lack of hygiene or trauma to the eye. Inflammation of the cornea can lead to symptoms such as eye redness, eye pain, foreign body sensation in the eye, photophobia, tearing, and loss of vision. When inflammation occurs, eye secretions contain pathogens, and if a healthy person comes into contact with these secretions and rubs his or her eyes, it is easy for the pathogens to infect the healthy person’s eyes, thus causing keratitis to become infectious. In order to avoid the transmission of keratitis, we must do a good job of personal protection, do not share washbasins, towels and other personal hygiene products, pay attention to hygiene, do not rub the eyes and so on.
