[Epidemiological investigations transmisssion of Q fever among humans in Bosnia and Herzegovina].

Appearance of an acute disease by Coxiella burnetii in humans in Bosnia and Herzegovina is very big epidemiological problem because incidence rate is among the highest incidence rates in Europe. Incidence rate of Q fever in Federation Bosnia and Herzegovina was very high during 1998. year 5.68% and the highest in 2000, with 115 diseases with acute clinical form of the disease and incidence rate of 6.95%. The incubation period varied from 9 to 28 days. Real incidence rate because of asymptomatic appearance of the disease is very much higher, at least 40-50 times higher. Chronic infection with Coxiella burnetii has been the most common developed as infectious endocarditis, which is the hardest complication. The researches of mode of transmission Q fever in humans showed that this disease spreads in epidemic and sporadic form in Bosnia and Herzegovina. In the period 1998-2003 year, there were 373 cases of Q fever, among them 265 or 71,05% cases epidemic transmission, and 108 or 28,95% cases sporadic. The research of outbreaks of Q fever showed that appearance of Q fever is statistical significant with risk factors at 266 cases of disease. The mode of transmission in 107 cases was the most probably across inhalation of infected aerosols.
