People commonly get conjunctivitis by coming into contact with the tears or other eye discharges of an infected person, and then touching their own eyes. Hands, towels and washcloths can spread conjunctivitis.
For bacterial conjunctivitis, the symptoms usually begin 24 to 72 hours after exposure to the infection. For viral conjunctivitis, the onset of symptoms can range from 12 hours to 12 days after infection. The symptoms can persist for several days, or rarely, for 2 to 3 weeks.
Pink eye is most often caused by a virus. It usually occurs at the same time as or right after you have had a cold. Less commonly, pink eye can be caused by infection with bacteria. Dry air, allergies, smoke, and chemicals can also cause pink eye.
"Pink eye" (conjunctivitis) is an inflammation and redness of the conjunctiva (the layer of blood vessels covering the white part of the eye). It can appear suddenly or overnight.
Early signs of pink eye include redness, irritation, itching, and watery eyes. People may have a gritty feeling in the eye and discharge. In many cases, conjunctivitis will resolve by itself within a few weeks. Home remedies, such as artificial tears and warm or cool eye compresses, may help ease symptoms.
This is a popular myth amongst school-age pranksters that asserts a person who uses a pillowcase that a practical joker farted on will later contract pink eye. You cannot get pink eye from a fart. Flatulence is primarily methane gas and does not contain bacteria. Additionally, bacteria die quickly outside the body.
Inflammatory Conjunctivitis is pink eye caused by some irritation to the eye such as contact lens over wear, getting hit in the eye, dust, dirt, or chemical exposure (fumes, liquid, or solids), excessive rubbing of the eye, crying, not getting enough sleep, and dryness of the eye (from staring at a computer, or being ...
If you have conjunctivitis but do not have fever or other symptoms, you may be allowed to remain at work or school with your doctor's approval. However, if you still have symptoms, and your activities at work or school include close contact with other people, you should not attend.
Pinkeye that's caused by bacteria can spread to others as soon as symptoms appear and for as long as there's discharge from the eye — or until 24 hours after antibiotics are started. Conjunctivitis that's caused by a virus is generally contagious before symptoms appear and can remain so as long as the symptoms last.
Stress does not cause pink eye, but one cause of viral conjunctivitis is the herpes virus, which stays dormant in a person's body and can be activated when they experience stress. This can lead to cold sores on the lip, skin rashes, or eye infections such as pink eye.
What causes pink eye? Most of the time, pink eye is caused by a virus or bacteria. Viral pink eye is the most common type. You can also get pink eye from allergies to things like pollen or pet fur — or from other things that can bother your eyes, like pool water with chlorine, air pollution, or makeup.
Stages of bacterial pink eye
A typical bacterial case may start like viral pink eye, with slight irritation and redness. Then drainage in the form of pus will become noticeable. This is usually white, yellow or yellow-green in color. As it dries, it will leave a crusty film on the eyelids.
Pink eye is spread by hand-to-eye contact or if the eye comes in contact with contaminated objects. Viral and bacterial conjunctivitis can also be spread through the air by coughing and sneezing, according to the CDC.
A doctor will advise on when to return to work or school, but people should not attend if they have symptoms and will be working closely with others. Pink eye caused by a virus is usually highly contagious for 10–14 days.
If you think you (or your child) might have pink eye, it's best to see an eye doctor who can perform a physical exam to confirm diagnosis. Left untreated, certain types of pink eye (the bacterial varieties) can lead to infections of the cornea, eyelids and even tear ducts.
Wash Sheets and Linens
Sleeping on the same bacteria filled pillowcase every night can only cause you severe problems— like pink eye. As one of the first steps you should take when discovering that either yourself or your child has pink eye is to wash all of your sheets and linens in hot water.
The infection will usually clear up in 7 to 14 days without treatment and without any long-term consequences. However, in some cases, viral conjunctivitis can take 2 to 3 weeks or more to clear up. A doctor can prescribe antiviral medication to treat more serious forms of conjunctivitis.
There is no cure for viral conjunctivitis. Recovery can begin within days, although the symptoms frequently get worse for the first three to five days, with gradual improvement over the following one to two weeks for a total course of two to three weeks.
There's a reason pink eye is more common in winter, though. “Because it's spread through direct contact, it can be passed around easily by people who have bacterial or viral conditions like cold or flu — which are also more common in colder weather months,” Dr. Singh says.
What does pink eye look like? In an eye with pink eye, the white part looks light pink to reddish and your eyelids are puffy or droopy. You might see fluid (discharge) coming from the infected eye or crusting on your eyelashes and eyelids.
Since conjunctivitis is usually viral, antibiotics won't help. They may even cause harm by reducing their effectiveness in the future or causing a medicine reaction. Instead, the virus needs time to run its course. This typically takes around 2 to 3 weeks.
