The role of small rodents and patterns of living in the epidemiology of nephropathia epidemica.

The epidemiological role of small rodents and certain human patterns of living for contraction of nephropathia epidemica (NE) was studied by interviewing 46 NE patients and 52 control subjects. The occurrence of small rodents in dwellings and cupboards was significantly commoner among NE patients than among control subjects. The results suggest a connection between NE and small rodents.
