Case Study: Diagnosis, Treatment, and Prevention of Conjunctivitis

This case study analyzes the case of a patient, John, diagnosed with acute bacterial conjunctivitis. It begins by defining infectious conjunctivitis and identifying the causative microorganism, Staphylococcus aureus, justifying its role over other potential pathogens like Legionella pneumophila, Plasmodium ovale, and adenovirus. The study then details the mechanism of action of the prescribed antibiotic, gentamicin, and its adverse reactions. It explores the physiological basis of signs such as red eye, mucopurulent secretion, and chemosis, explaining the underlying mechanisms. The case study also addresses infection control issues, emphasizing healthcare worker hygiene, environmental cleanliness, and the use of sterile equipment. Finally, it outlines the transmission of infection from John to Mary and identifies procedures to break the chain of infection, including handwashing, the use of masks, and antibiotic eye drops. The study utilizes multiple sources to support the presented information.
