H10: Conjunctivitis

Conjunctivitis, often referred to as "pink eye", is a group of conditions that cause inflammation or infection of the outer membrane of the eyeball and the inner eyelid. It's largely caused by infectious bacteria or viruses, allergic reactions, or irritants like dirt, smoke, or chemicals. Conjunctivitis is highly contagious if caused by an infection, and it spreads through direct contact with infected individuals or indirect contact with contaminated objects. Symptoms often include redness, itching, and a gritty feeling in the eye, accompanied by discharge that can form a crust. While some types of conjunctivitis may resolve on their own, others might require medical treatment. When untreated, it can lead to complications affecting vision. Immunocompromised individuals and those with pre-existing eye conditions could potentially be at a higher risk of severe disease progression.
