Causes Of Conjunctivitis (Pink Eye) And Things To Avoid


Conjunctivitis (Pink Eye) can result from an allergy, an irriation, or an infection, a virus or a bacteria can cause an infection. Sometimes it is linked to a sexually transmitted infection (STI), antibiotics are sometimes used, but they will not help if the cause is a virus.
The Symptoms of Conjunctivitis normally last up to 2 weeks, but they can persist for longer.

You're more likely to develop infective conjunctivitis if you've been in close contact with someone who's already infected with it.
It's therefore very important to wash your hands thoroughly after coming into contact with anyone who has infective conjunctivitis. You should also avoid sharing pillows or towels with anyone with the infection.

Conjunctivitis are divided into different types based on the cause, the most common causes are
. Infection (Infective Conjunctivitis)
. Allergic reaction(Allergic Conjunctivitis)
. Irritant conjunctivitis

Infective conjunctivitis
Eye infections are most commonly caused by:
. Bacteria - for example, the strains of bacteria that often cause lung and ear infections
. Virus - most commonly an adenovirus that may also cause a sore throat and high temperature (fever)
. Sexually transmitted infections (STIs) - such as chlamydia or gonorrhoea

Allergic conjunctivitis
allergic conjunctivitis are usually caused by:
. Pollen from grass, trees or flowers
. Dust mites
. Flakes of dead animal skin

Irritant conjunctivitis
Irritant conjunctivitis can have a wide range of potential causes. Some common causes include:
. Chlorinated water used in swimming pools
. Shampoo
. A stray eyelash rubbing against the conjunctiva
. Smoke or fumes


Causes In Newborn Babies
Pink eye in newborns can be due to infection, irritation, or a blocked tear duct. The cause can be hard to determine, because each type produces similar symptoms.
Sometimes bacteria or a virus is passed on from the mother during delivery, even if she does not have symptoms. The bacteria or virus may be related to an STI.

More On The Causes
Infection in the eye can be due to a virus or bacteria. Viruses that cause conjunctivitis include adenoviruses and some types of herpes virus. Bacterial causes include Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus species, and, less commonly, Chlamydia trachomatis.
Bacterial conjunctivitis is sometimes caused by a sexually transmitted infection (STI), such as Chlamydia . If symptoms do not disappear after a month, this may indicate an STI. Most other types of bacterial conjunctivitis will resolve more quickly with treatment. Infective conjunctivitis is extremely contagious and can easily be passed on to another person.
