In 1872, Daae-Finsen reported an epidemic of "acute muscular rheumatism" occurring in a community called Bamble, giving rise to the name "Bamble disease" in Norway. Subsequent reports, published only in Norwegian, referred to the disease by this name. In 1933, Ejnar Sylvest gave a doctoral thesis describing a Danish outbreak of this disease on Bornholm Island entitled, "Bornholm disease-myalgia epidemica", and this name has persisted.[9]
