Dr. Selviana, Indah Budiastutik, Dr. Mirto, Linda Suwarni


Background  Tinea imbricata is a recurrent chronic dermatophytosis caused by Trichophyton concentricum. In West Kalimantan, Indonesia, this disease is endemic and only occurs in Teluk Pongkal Village, Melawi Regency. There is no known presence of T. concentricum as the trigger factor for the occurrence of Tinea imbricata yet. This study aims to analyze the presence of T. concentricum fungi in the environment around the house and the relationship of employment with a history of transmission of Tinea imbricata in Teluk Pongkal Village, Sokan District, Melawi Regency.


Methods This research was observational with cross sectional approach. A sample of 31 incidences of Tinea imbricata in August 2016. Macroscopic and microscopic methods were used for identification of T. concentricum. Data analysis used the Fisher's Exact Test (α = 0.05).


Results The study showed that T. concentricum fungi were found on towels (45.2%), bed sheets (41.9%), and indoor air (38.7%). The presence of the T. concentricum on the towel (p = 0.031; PR = 3.238), bed sheets (p = 0.021; PR = 3.692) and indoor air (p = 0,007; PR = 4.222 95%) were significantly associated with a history of transmission of Tinea imbricata. Illegal gold miners are at risk for the occurrence of Tinea imbricata.


Conclusion  T. concentricum was found on towels, bed sheets, and indoor air. It was greater in patients with a history of transmission of Tinea imbricata .
