Bacterial conjunctivitis, often called pink eye, is an infection of the conjunctiva, the thin membrane covering the white part of the eye and the inner eyelids. This condition is usually caused by bacteria, leading to symptoms like redness, swelling, and discharge from the eye. It can affect people of all ages and is often contagious, spreading through direct contact with infected individuals or contaminated surfaces. Treatment for bacterial conjunctivitis typically involves antibiotic eye drops or ointments prescribed by a doctor. It's important to maintain good hygiene, such as washing hands frequently and avoiding touching the eyes, to prevent the spread of the infection. Most cases resolve within a week with proper care.
