Almost simultaneous onset of Vogt-Koyanagi-Harada syndrome in co-workers, friends, and neighbors.
OBJECTIVE
To report almost simultaneous onset of Vogt-Koyanagi-Harada (VKH) syndrome in co-workers, friends, and neighbors.


METHODS
The onset of VKH syndrome in six patients was examined.


RESULTS
Patient 1 and Patient 2 worked in the same room of an office and developed VKH syndrome 3 weeks apart from each other. Patient 3 and patient 4 were friends, lived in the same city, and developed VKH syndrome 1 month apart. Patient 5 and patient 6 lived in the same suburb and developed the syndrome 1 month apart.


CONCLUSIONS
Almost simultaneous onset of VKH syndrome in co-workers, friends, and neighbors may suggest an exogenous factor such as viral infection in the pathogenesis.
