Pink eye (Conjunctivitis) is a common infection that causes itchiness and redness in the white part of your eyes. It is characterized by the inflammation of the membrane that lines the inner eyelid.
This prevalent condition impacts around 6 million individuals in the United States annually.
This is because pink eye is extremely contagious and can readily spread from person to person.
If you have pink eye, it is important to avoid close contact with others until the infection clears up. But, many wonder, “How long is pink eye contagious?”
This article examines the contagiousness of pink eye, its mode of transmission, and measures to prevent its spread.
How long is pink eye contagious
The contagious period of pink eye depends on its cause. Pink eye can develop due to infections from viruses, bacteria, or allergies.
Among these, viral pink eye is the most contagious and continues to spread as long as it releases discharge. Bacterial pink eye is also contagious but stops spreading after antibiotics.
Viral pink eye
Viral pink eye, or Viral Conjunctivitis, is the most prevalent and contagious type of pink eye. It is contagious for about 10 to 14 days.
Infections from viruses, such as adenovirus cause this type of pink eye. These viral infections easily spread from one person to another through direct or indirect contact.
This infection remains contagious as long as there is pink eye discharge from the infected eye. The eye may continue producing this discharge for up to two weeks.
Bacterial pink eye
Although infectious, Bacterial Conjunctivitis is typically less contagious than its viral counterpart. It stops spreading after taking antibiotics.
This condition is caused by bacterial infections, which include Staphylococcus aureus, Haemophilus influenzae, and Streptococcus pneumoniae.
The infection spreads through direct contact with eye secretions or indirect contact with infected surfaces.
Typically, bacterial pink eye stops being contagious around 24 hours after antibiotic treatment.
Allergic pink eye
Allergic Conjunctivitis, caused by allergens like pollen, dust, or pet dander, is not infectious. It occurs due to an allergic reaction rather than infectious agents.
The symptoms of allergic pink eye can persist if there is continued exposure to allergens.
How to prevent spreading pink eye
While pink eye is highly contagious, you can avoid spreading it to others by following certain preventive measures.
It is crucial to exercise precaution and protect yourself and others if you have pink eye. Follow these steps to avoid spreading pink eye:
- Avoid touching or rubbing your eyes
- Wash your hands often, especially if you touch your eyes
- Regularly clean and disinfect commonly touched surfaces
- Use separate towels, pillowcases, and facecloths
- Avoid sharing personal items like makeup or contact lenses
