Conjunctivitis "Pink Eye"
What are the risk factors?
The risk factors associated with conjunctivitis are dependent on the cause of the inflammation and, in some cases, age.
The most common seasonal allergic conjunctivitis risk factor is exposure to an environmental irritant. Specific environment irritants change with the seasons.
In the case of bacterial conjunctivitis the risks vary depending on age. For new born infants, bacteria may be transferred from the mother during vaginal delivery. The factor that increases the risk of infection in the infant is less than adequate prenatal care for the mother. For infants and children the bacteria may be spread by exposure to an infected individual or by chronic ear infections. Adults may contract bacterial conjunctivitis from contact, tear deficiency, or trauma.
Risk for viral conjunctivitis may be increased if one is exposed to an infected individual or if there is a history of sinus infections and congestion.
If the form of conjunctivitis is contagious, it is important to take steps to reduce the chance of spreading it by limiting direct contact and practicing good hygiene. This includes:
- Avoid touching or rubbing the infected eye(s).
- Wash hands with soap and water frequently.
- Avoid sharing towels or other items that come into contact with the hands or eyes.
Persons with viral or bacterial conjunctivitis may stay contagious for 1 to 2 weeks after signs and symptoms first appear.
