Conjunctivitus

Your eyes are extremely sensitive. As such, the slightest irritant or infection can cause a great deal of pain and irritation. It can also lead to conjunctivitis, an inflammation of the thin layer of tissue covering the front of the eye, known as the conjunctiva. Conjunctivitis caused by a bacterial or viral infection are highly contagious.

In most cases, conjunctivitis doesn’t pose a serious health threat and will clear up on its own after a couple of weeks. However it’s important that you consult with your doctor so they can determine the cause and prescribe the right course of treatment Neo-natal conjunctivitis, which affects newborn babies younger than 28 days, can lead to more serious health complications. If you have a new baby and you think they may have it be sure to contact your GP or HCP as soon as possible.
