SALCEDO MIQUELEIZ, Asunción et al. A nosocomial and community outbreak of epidemic keratoconjunctivitis in Navarre, Spain, in 1996. Rev. Esp. Salud Publica [online]. 1997, vol.71, n.4, pp.383-390. ISSN 2173-9110.

BACKGROUND: Epidemic keratoconjunctivitis is an acute, generally bilateral infection, that appears sporadically or in outbreaks from a source of common infection which may be a visit to the ophthalmologist or a swimming pool. Keratis may evolve to form sub-epithelial injuries in the cornea lasting as much as several months. METHODS: Description of an outbreak of epidemic keratoconjunctivitis that took place in Navarre (Spain) between April and August 1996 and which affected at least 266 people. RESULTS: The epidemiological research highlights the existence of two ophthalmologist visits as the transmission mechanism for the infection in 47 of the 116 patients researched. The spread of the infection in the environment of the patients was recorded in 119 cases, 62 of which are considered secondary cases. The aetiological diagnosis of the outbreak was carried out 11 days after the start of the microbiological research, isolating adenovirus in conjunctival samples of 8 of the 19 patients researched. CONCLUSIONS: The preventive measures taken to control the outbreak and their effectiveness was highlighted by the gradual reduction in cases.
