Final answer:
Conjunctivitis, also known as pinkeye, is an inflammation of the conjunctiva. It is caused by infections from bacteria or viruses, allergens, or chemicals, with the bacterial form being highly contagious. Good hygiene and medical attention are important to prevent its spread.
Step-by-step explanation:
The condition that is also referred to as pinkeye is conjunctivitis. This medical condition is an inflammation of the conjunctiva, which is the thin clear tissue that lies over the white part of the eye and lines the inside of the eyelid. Conjunctivitis can be caused by infections from bacteria or viruses, but it can also result from allergens, pollutants, or chemicals. The bacterial form of conjunctivitis is highly contagious and can include symptoms such as the discharge of a sticky fluid, whereas viral conjunctivitis may involve a watery discharge and often occurs alongside upper respiratory infections.
Bacterial conjunctivitis, often presenting with purulent discharge, is usually caused by bacteria such as Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae, and Staphylococcus aureus. It is important to practice good hygiene and seek medical attention for proper diagnosis and treatment to prevent spreading the infection. Conjunctivitis is differentiated from other inflammations like blepharitis, which is inflammation of the eyelids, and keratitis, which is inflammation of the cornea.
