title: [The influence of meteorological factors for frequency of Herpes simplex keratitis].
abstract: OBJECTIVE
  The variation of the meteorological factors could be a stress for the organism, which could determine the start of some diseases.
  
  
  METHODS
  We studied 252 cases of herpes simplex keratitis which had been hospitalized in Eye Clinic of Cluj between 1983-1991. The selection criteria were: known diagnosis; day of the rise could be exactly established; disease was taken place in Cluj or in region not longer than 30 km on Somes Valley. The meteorological parameters were collected by specialist from the Meteorological Station of the city and from the Cluj's Airport. The results were verified statistical and were guaranted by p = 0.05.
  
  
  RESULTS
  The herpes simplex keratitis are more frequently in days with a temperature higher and an atmospheric pressure lower than the average value of the season.
  
  
  CONCLUSIONS
  We drew a possible pathogenic mechanism to explained the reactivation of the virus under the influence of warm weather.
