Pink Eye or Conjunctivitis is an eye infection involving the inflammation of the conjunctiva, which covers the white area of the eye.

It can occur due to bacteria, viruses, and allergens, leading to painful, itchy, and red eyes. 

But is Pink Eye contagious, and can spread to other people?

This article will explore if Pink Eye is contagious or not, how it spreads and its preventive measures.

Is Pink Eye contagious

Pink Eye can be contagious or non-contagious depending upon the underlying cause.

The infection can be contagious if caused by the bacteria and viruses that spread from contact. 

These include adenovirus, herpes simplex virus, and bacteria causing cold and respiratory infections.

The same pathogens can lead to cold and other infections, such as ear, sinus, and sore throat.

Pink Eye infections can also develop from the bacteria that cause Gonorrhea and Chlamydia, two sexually transmitted diseases (STDs). 

The bacteria can get into the eye if someone touches the genitalia of an infected person and then rubs their own eye or comes into contact with a contact lens.

Bacterial Pink Eye can be transmitted to other people as soon as symptoms start to develop. 

It can persist as long as there is liquid discharge from the eye or up to 24 hours after starting antibiotics. 

Viral Pink Eye can often spread even before the symptoms appear and might continue as long as the Pink Eye symptoms last. 

On the other hand, certain types of Pink Eye, such as Allergic Pink Eye caused by an allergic response, are not contagious. Irritant Pink Eye, which can be brought on by anything that irritates the eyes, such as pool chlorine or air pollution, is also non-contagious.

Suggestion:
Don’t wear makeup if you have Pink Eye; it may worsen your symptoms.

Pink Eye infection can be spread from one person to another just like any other bacterial and viral infection.

In the case of bacterial and viral Pink Eye, it takes around 24 to 72 hours for the onset of the symptoms and infection.

Pink eye, whether bacterial or viral, can be spread to other individuals in the following ways: 

  • Sharing personal belongings
  • Shaking hands or making direct contact 
  • Applying contaminated or outdated makeup that has accumulated bacteria
  • Touching eyes with unclean hands
  • Using contact lenses in areas where infections exist
  • Using objects contaminated with bacteria or viruses and then touching your eyes with the infected hands 
  • Sneezing and coughing
