Aetiological relation between Korean haemorrhagic fever and nephropathia epidemica.

A close aetiological relation between Korean haemorrhagic fever and nephropathia epidemica of Scandinavia has often been suggested because of similarities in their clinical picture and epidemiology. This relation has now been confirmed serologically; raised titres of antibody to Korean haemorrhagic fever agent and seroconversions have been found by the indirect fluorescent-antibody technique in 20 patients with nephropathia epidemica.
