A trial of methods for mass inoculation.

Two cases of scrub typhus are described. In both, the existence of a genital eschar with regional adenitis pointed to venereal infection. Although only two cases have been recorded during the previous two years at the Venereal Disease Department of the British Military Hospital, Singapore, it is possible that others have been missed and it is considered that scrub typhus should enter into the differential diagnosis of certain types of genital ulcers, particularly those occurring in soldiers serving in areas where scrub typhus is endemic. Thanks are due to Colonel R. J. G. Morrison, Consultant Physician, Far East Land Forces, for his encouragement.
