DEER KED (LIPOPTENA CERVI) DERMATITIS IN HUMANS – AN INCREASING NUISANCE IN FINLAND
The deer ked (Lipoptena cervi) is a haematophagous ectoparasite of moose (Alces alces) and other cervids that commonly bites humans in Finland. Since the 1970s there has been an increasing number of Finns who suffer from long-lasting and recurrent dermatitis associated with deer ked bites. Forestry...

The rapid range expansion of the deer ked in 1970-1990s seems related to the concurrent increase in moose population density in Finland.
