None of the members of the health center staff developed conjunctivitis during the outbreak, despite a regular flow of patients through the clinic. This experience differs markedly from those in other reported outbreaks of adenoviral conjunctivitis, in which health care settings have served as amplifiers and strict infection-control practices have been required in order to end the outbreaks.25 The absence of conjunctivitis among exposed health care workers suggests that contact with infected patients in a health care setting is not an efficient route of transmission for pneumococcal conjunctivitis.
