In recent times, there has been a significant increase in the number of patients with “pink eye”, and the symptoms are relatively heavy, many people with keratoconjunctival lesions, medically known as “epidemic keratoconjunctivitis”. This disease is highly contagious, once the patient is infected, the condition will often be delayed for several weeks, bringing a lot of inconvenience to work and life, so it is important to do a good job of personal hygiene to prevent infection. The route of infection of “pink eye” is generally indirect contact: diseased eyes > hands (patients) > objects (banknotes, door handles, handrails of buses, etc.) > hands (healthy people) > eyes (healthy people). Prevention is to wash hands with soap as soon as possible after contact with public facilities, do not rub your eyes with your hands, and separate towels and basins when you have a patient with “pink eye” at home. As a patient yourself, wash your hands immediately after touching your own eyes, and then touch other common items. Once infected with “pink eye”, go to the hospital as soon as possible, apply antibiotic eye drops for treatment, do not apply sticky eye ointment, which will affect the excretion of secretions and aggravate the disease. If the condition is serious enough to affect the cornea, you can apply hormonal eye drops under the guidance of your doctor, but don’t do it on your own, because hormones have many side effects.
