Conjunctivitis, commonly known as pink eye, is a widespread eye condition characterized by inflammation of the conjunctiva. This thin, clear membrane covers the white surface of the eye and lines the inside of the eyelids. When the conjunctiva becomes inflamed, the small blood vessels within it enlarge, causing the eye to appear red or pink and leading to general discomfort.
Understanding Pink Eye’s Contagion
The contagiousness of pink eye largely depends on its underlying cause, which falls into viral, bacterial, or allergic categories. Viral conjunctivitis, the most frequent type, is highly contagious, often spreading similar to a common cold through direct contact with eye secretions or contaminated surfaces. Individuals with viral pink eye can transmit the infection even before symptoms fully appear and remain contagious as long as symptoms persist for 10 to 14 days.
Bacterial conjunctivitis is also highly contagious, transmitted through direct contact with eye discharge. This form remains contagious as long as there is discharge from the eye. If treated with antibiotics, the contagious period ends 24 hours after starting the medication; without treatment, it can remain contagious for one week. In contrast, allergic conjunctivitis is not contagious at all, as it results from the body’s immune response to allergens like pollen or dust.
Guidelines for Work or School Attendance
Deciding whether to attend work or school with pink eye depends directly on its cause and the presence of symptoms. For those with allergic conjunctivitis, returning to work or school is safe immediately since this type is not contagious. Symptoms of allergic pink eye are often managed by avoiding the allergen and using antihistamines or eye drops.
If diagnosed with bacterial pink eye, it is recommended to stay home until symptoms have significantly improved or ceased. If antibiotics are prescribed, individuals can return to their activities 24 hours after beginning treatment. While symptoms may fully resolve in two to five days with treatment, complete healing can take up to two weeks.
Viral pink eye requires individuals to remain home until they have fully recovered and all symptoms have subsided. This recovery period ranges from one to two weeks.
It is important to consider workplace or school policies. Some settings may require a doctor’s note or a specific symptom-free period before returning. Regardless of the type, maintaining rigorous hygiene practices upon returning is advised to prevent any potential spread.
Preventing Further Spread
Preventing the spread of infectious pink eye involves consistent hygiene practices. Frequent and thorough handwashing with soap and water for at least 20 seconds is important. It is important to avoid touching or rubbing the eyes with unwashed hands.
Individuals with pink eye should refrain from sharing personal items such as towels, washcloths, pillowcases, eye drops, or eye makeup. Changing pillowcases and bed linens daily or frequently minimizes germ transmission. If you wear contact lenses, it is advisable to stop wearing them until the infection clears and discard any lenses or cases used during the infection period. Cleaning eyeglasses regularly is also beneficial.
When to Seek Medical Advice
While many cases of pink eye are mild and resolve on their own, certain symptoms warrant prompt medical attention. A healthcare provider should be consulted if there is severe eye pain, changes in vision, or blurred vision. Extreme sensitivity to light, known as photophobia, also signals a need for professional evaluation.
Seek medical advice if symptoms worsen or do not show improvement after a few days. Other concerning signs include a persistent feeling that something is stuck in the eye, or the presence of a large amount of eye discharge. Individuals with a compromised immune system or newborns exhibiting any pink eye symptoms should be seen by a doctor immediately.
