Bacterial and viral conjunctivitis are highly contagious. Unless you take preventive measures, the condition may spread to your other eye or to other people.
Practice good hygiene by washing your hands often and well, and keeping them away from the infected eye.
Avoid sharing bedding, towels, face washers or handkerchiefs with other family members.
Children with infectious conjunctivitis should be kept home from school.
Always use eye protection when cycling, swimming, or using industrial materials such as chemicals or powdered cement.
Keep your home clean and well-ventilated to reduce the build-up of dust mites and mould.
