Step-by-step explanation:
The infection of the transparent membrane that lines the eyelid and eyeball is known as conjunctivitis, more commonly referred to as pink eye. Conjunctivitis is an inflammation condition capable of presenting in various forms, including acute purulent with pus formation or acute hemorrhagic with bleeding.
Bacterial conjunctivitis, which is highly contagious and characterized by inflammation and discharge, is most commonly caused by bacteria such as Haemophilus influenzae, Moraxella catarrhalis, S. pneumoniae, and S. aureus.
