During March, 1981, a number of cases of dengue fever occurred in Cairns and Townsville, northern Queensland. From October, 1981, an outbreak of the infection was recognized on Thursday Island and, by May 1982, an estimated 38% of residents had been infected. Isolated cases were reported from other towns in northern Queensland and from other islands in the Torres Strait. ⋯ No deaths were reported. Entomological surveys indicated that the domestic breeding vector of dengue, Aedes aegypti, is widely distributed throughout Queensland - southwards to Dirranbandi and westwards to Mornington Island. In some localities, the indices of Ae. aegypti abundance are alarmingly high, but at least in some suburbs of Townsville, it has been effectively controlled.

Seventy prostitutes were screened at their place of work, a Sydney house of prostitution, on a weekly basis over one year. Of these, 10% acquired new infections with gonorrhoea each week (53 episodes). ⋯ Stability of the place of work appeared to be associated with a lower isolation rate (5.5%). Five asymptomatic, urethrally infected men (two clients, three boyfriends/husbands) were detected, and appeared to have an important role in the hyperendemicity of gonorrhoea in this environment.
