Pink eye is caused by a viral or bacterial infection and is highly contagious.
It can be spread by contact with contaminated fingers, towels, handkerchiefs, or wash cloths. Symptoms may include swelling, redness, irritation, and pus which causes the eyelids to stick together. The infection is usually treated with antibiotic drops or ointment which must be prescribed by a doctor. Certain precautions can help prevent spread of pink eye. The hands should be washed frequently and fingers kept away from the eyes.
