Acute bacterial conjunctivitis, commonly known as pink eye, should be transmitted mostly by contact. The main thing is to take precautions and avoid direct or indirect contact. Acute bacterial conjunctivitis is mostly caused by bacterial or viral infections, which can be transmitted through objects. Therefore, it is important to pay strict attention to personal and group hygiene, advocate diligent hand washing, and not to wipe the eyes with hands or objects that have been in contact with the patient to prevent pathogens from entering the eyes of healthy people directly causing new acute bacterial conjunctivitis infections in patients. Prevent epidemics, pay attention to the disease to prevent infection of the other eye, strictly disinfect the patient’s bathing utensils, and health care workers must wash their hands after contact with the patient to prevent cross-infection. Newborns can use 1% silver nitrate eye drops, 1% tetracycline eye ointment coated eyes to prevent neonatal gonorrheal conjunctivitis and chlamydial conjunctivitis. Patients’ used washing utensils and tableware must be isolated and disinfected, and medical staff must wash their hands and disinfect after examination to prevent cross-infection. In conclusion, acute bacterial conjunctivitis is mainly contagious by contact, so it is important to pay extra attention to avoid contact with things used by others or to wash them immediately after contact. Once acute bacterial conjunctivitis is detected, care must be taken to isolate it to avoid infecting others.
