[Q-fever imported into Norway].

Q fever is an important zoonosis that occurs throughout the world. In contrast to most other European countries, there has been no evidence of endemic Q fever in Norway up to now. The disease is caused by Coxiella burnetii, a rickettsia-like bacterium. Humans are infected mainly by inhalation of contaminated aerosols from cattle, sheep and goats. Clinical manifestations are protean, ranging from asymptomatic infection to life-threatening endocarditis. In this article we present the first four cases of serological proven acute Q fever imported into Norway. The patients were Norwegian tourists who had visited Bhutan, the Canary Islands, and Morocco. Two patients had fever with maculopapular exanthema, one had pneumonia, and one had biopsy-proven granulomatous hepatitis. Three were treated with tetracyclines. All four patients recovered well.
