It has long been suspected that the disease is caused by aSindbis-like virus, a positive-strandedRNA virus belonging to theAlphavirus genus and familyTogaviridae.[1] In 2002 a strain of Sindbis was isolated from patients during an outbreak of the Pogosta disease inFinland, confirming the hypothesis.[3]
There is currently no treatment available.
This disease is mainly found in the Eastern parts ofFinland; the disease was first detected in 1974 in the old parish village ofIlomantsi, sometimes calledPogosta.[4] A typical Pogosta disease patient is a middle-aged person who has been infected through amosquito bite while picking berries in the autumn. The prevalence of the disease is about 100 diagnosed cases every year, with larger outbreaks occurring in 7-year intervals.[3]
It is also known as Karelian fever and Ockelbo disease. The names are derived from the wordsPogosta,Karelia andOckelbo.[citation needed]
