It has long been suspected that the disease is caused by a Sindbis-like virus, a positive-stranded RNA virus belonging to the Alphavirus genus and family Togaviridae. [1] In 2002 a strain of Sindbis was isolated from patients during an outbreak of the Pogosta disease in Finland, confirming the hypothesis. [3]
There is currently no treatment available.
This disease is mainly found in the Eastern parts of Finland; the disease was first detected in 1974 in the old parish village of Ilomantsi, sometimes called Pogosta. [4] A typical Pogosta disease patient is a middle-aged person who has been infected through a mosquito 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 words Pogosta, Karelia and Ockelbo.[ citation needed]
