Two epidemiologically unrelated outbreaks of trichinellosis were registered in Rostov Province in the November and December of 1984 with 16 patients in the Salsk District and 20 patients in Rostov-on-Don. The course of the disease was characterized by 6-20% of severe and 31-45% moderate forms, respectively. The source of the infection was pork that had not been controlled for Trichinella spiralis. Late diagnosis and inadequate treatment in one case led to a fatal outcome. Economic losses accounted for 490,000 rubles (as of 1985). In spite of energetic prophylaxis measures, the situation in the Rostov Province continues to be serious. In 1989-1992, eighteen cases of trichinellosis were registered in the Salsk District again.
In contrast to the other Nordic countries Sweden has long had a favourable position as regards meningococcal disease. In the last 10 year period the annual incidence has been only about one case per 100,000 inhabitants. The treatment once the cause is confirmed is conventional and no different from that in the other Nordic countries but varies somewhat in the event of unknown etiology. Cortisone therapy also seems to be more frequent in treatment of meningitis. Two strategies for antibiotic prophylaxis are used in Sweden.
