عنوان مقاله [English]
According to the Centers for Disease Control and Prevention (CDC), there were 483 cases of recurrent tick-borne fever in the western United States between 1990 and 2011. Most cases were reported in California, Washington and Colorado. The epidemiological study of TBRF in Iran during 1997-2006 shows the higher prevalence of this disease in Qazvin and Hamedan provinces. In these two provinces, 8.8% of the mites of the species Ornithodorus tulozani are infected with Borrelia persica and half of the mites of the species Ornithodorus eraticus are infected with Borrelia microti. The disease can be a significant risk to soldiers and civilians. A study conducted in Israel between 1983 and 2003 reported 606 cases of TBRF, of which 283 were civilians and 323 were military personnel. The high prevalence in the military is due to the presence of the pathogen and its carrier in Israel and to the fact that the military is at risk due to the type of activity. The disease also occurs during the Israeli wars. Most TBRF reports occur annually, in summer and autumn, which may be due to the high activity of Ornithodorus, the greater activity of people outdoors, and the wearing of thin clothing during these seasons. 63% of infected soldiers in Israel are infected in hot and dry environments, most likely due to military training in these areas. So far, no study has been done on the frequency of this disease in soldiers during training courses in Iran. There are similarities between the clinical signs of bacterial, viral and parasitic pathogens and the clinical signs and manifestations are nonspecific. Early misdiagnosis is the most common cause of neglect, especially in the military population.
