Between August 1990 and November 1991 there were five confirmed cases of scrub typhus (Rickettsia tsutsugamushi) acquired in Litchfield Park. A further case from Litchfield Park acquired in October 1993 was diagnosed in a Western Australian tourist. The case described above from June 1996 is the seventh confirmed case. Until these cases and a case from the Kimberley in July 1993 it was generally considered that scrub typhus in Australia did not extend west of north east Queensland. Our investigations suggest more than one location within Litchfield Park as infecting sites for scrub typhus.
