The condition, also known as conjunctivitis, is a general inflammation of the white part of the eye and the inside of the eyelids, and is known for running rampant through schools and day cares.
There are several causes of pink eye with different symptoms and levels of contagion.
Here is what parents need to know about the different types of conjunctivitis.
Bacterial
Bacterial conjunctivitis causes these symptoms to one or both eyes:
- Red or pink eye(s) that are itchy and painful.
- A large amount of green or yellow discharge.
- Eyes that are crusted shut in the morning.
This type of pink eye can be treated with antibiotic eye drops. It is contagious 24 to 48 hours after starting medication or until symptoms subside.
Viral
Viral conjunctivitis may affect only one eye with symptoms such as pink, inflamed, and watery eye(s) that are sensitive to light.
Viral pink eye remains contagious for as long as signs or symptoms are present.
Adenovirus is a specific viral infection that can cause pink eye. It spreads easily and can be contagious for weeks after symptoms appear. This infection can also cause children to have a fever, sore throat, and other respiratory symptoms.
Since antibiotics do not help the patient or prevent the spread of the infection, treatment is not usually needed for viral conjunctivitis. However, antibiotic eye drops are sometimes used to prevent secondary infection.
Allergic
Itching, redness, and excessive tearing, typically in both eyes, are most likely caused by allergies.
The reaction can be immediate or appear several hours or days after coming in contact with the allergen.
Conjunctivitis caused by allergies is not contagious and can be treated with oral medicines or eye drops.
Chemical
Most commonly seen after swimming in a chlorine pool, chemical conjunctivitis brings on red and watery eyes and is not contagious.
Bacterial and viral conjunctivitis are spread when eye discharge or respiratory droplets from an infected person gets into another person’s eyes. Control the spread of pink eye by washing hands, especially before and after touching the eyes, nose, and mouth, and sanitizing frequently touched items.
Symptoms of conjunctivitis can seem like other health conditions. While rare, pink eye can also be an indication of Kawasaki disease.
If you suspect your child has pink eye, make sure to visit your healthcare provider for a diagnosis.
