Bacterial conjunctivitis is an eye infection caused by bacteria that leads to inflammation of the conjunctiva, the thin membrane covering the white part of the eye and the inner eyelids. Symptoms often include redness, swelling, and discharge, which can be yellow or green. It is commonly spread through direct contact with infected individuals or contaminated surfaces. Treatment typically involves antibiotic eye drops or ointments prescribed by a healthcare professional. Good hygiene practices, such as frequent handwashing and avoiding touching the eyes, can help prevent the spread of this condition. Most cases resolve within a week with proper care.
