Q Fever in human and livestock populations in Oman

Abstract

In 2000, Q fever was documented for the first time in the Sultanate of Oman in two patients, one with chronic pericarditis and the other with acute pneumonia. In 2001, a study of a randomly selected group of 102 adult patients from different provinces in northern Oman, presenting to the University Hospital in Muscat with unrelated conditions (e.g., diabetes mellitus, ischemic heart disease), revealed that 10 (9.8%) were seropositive for previous Coxiella burnetii infection. Examination of sera from a randomly selected group of 54 healthy goats from eight different herds from three different provinces of Oman, obtained by the Veterinary Research Center in Muscat, revealed that 28 (52%) had been infected, and 5 sheep, each from one of four herds, were seropositive for C. burnetii. We suspect that Q fever is widely prevalent in human populations in Oman, and that infection is widespread in goat, and probably sheep and other livestock populations, throughout the country.
