Infectious conjunctivitis can lead to epidemic infection, therefore it is essential to take preventive measures. Conjunctivitis is often spread through contact, thus it is advocated to frequently wash hands and faces, and avoid wiping eyes with hands or sleeves. Patients with infectious conjunctivitis must be isolated, and any toiletries used by the patients must be isolated and disinfected. Medical staff should also wash and disinfect their hands after examining patients to prevent cross-infection.
