Pink eye is not contagious through air. Instead, it spread through person-to-person contact. It can also be spread by the droplet from coughing and sneezing. When a person with pink eye shares the same towel or other articles of everyday use with other people, the contagion will certainly occur. If you have pink eye or a person around you have pink eye, you should use your own towel or other articles to avoid contagion. Keeping clean is very important to prevent pink eye. This means that you should make sure your eyes, face, hands and fingers are clean all the time to avoid bacteria or virus that cause pink eye.
