Human leptospirosis in Victoria.

Between May, 1979, and May, 1981, leptospirosis was diagnosed, on the basis of serological and culture findings, in specimens from 208 of 2516 patients with symptoms which suggested leptospirosis or other zoonoses. The most common serological reactions were with serovars hardjo (69%), pomona (29%) and tarassovi (2%). There was a clear association between infection and occupation in 101 farmers, 44 meat workers and 11 meat inspectors. It would seem prudent to consider leptospirosis in the differential diagnosis of pyrexia in patients who have occupational contact with animals, and to institute appropriate serological and culture examinations.
