[Early serological diagnosis of nephropathia epidemica].

The viral disease nephropathia epidemica is probably more common throughout Norway than previously reported. Since 1986, outbreaks of the disease have been registered every year but in different regions of the country. Very few cases have been reported in certain counties in spite of the presence of a small rodent reservoir for this zoonosis. Nephropathia epidemica may be underdiagnosed, since the disease is not equally well recognized in all parts of Norway. However, effective and reliable serological diagnostic tests are now available which use a single serum sample taken early in the acute phase of the disease. Test results are available at a time when they can help the physician to make an early diagnosis. This should lead to a more effective and rational treatment of these patients.
