Abstract:A 46-year-old woman with disseminated intravascular coagulation (DIC) died in a hospital in Alexandroupoli, in north-eastern Greece, in the end of June 2008. The woman was admitted to the hospital four days earlier, with fever, malaise, myalgia, chills and abdominal pain. One day before death, her condition deteriorated rapidly and she developed heavy hemorrhage from the genital tract, DIC and multi-organ failure. The patient reported a tick bite four days before admission, and that she had tried to remove the… Show more
“…In the meantime, a cluster of CCHF cases were observed in early spring 2008 in Southwestern Bulgaria, in an area considered previously at low risk for CCHF outbreaks . In June of the same year, the first (and fatal) CCHF case was reported in Greece . The CCHFV IgG seroprevalence in Greece ranges from 0% to 14%, with age (elderly), previous tick bite, and agropastoral activities being among the major factors associated with seropositivity .…”
Southern Europe is characterized by unique landscape and climate which attract tourists, but also arthropod vectors, some of them carrying pathogens. Among several arboviral diseases that emerged in the region during the last decade, West Nile fever accounted for high number of human cases and fatalities, while Crimean-Congo hemorrhagic fever expanded its geographic distribution, and is considered as a real threat for Europe. Viruses evolve rapidly and acquire mutations making themselves stronger and naive populations more vulnerable. In an effort to tackle efficiently the emerging arboviral diseases, preparedness and strategic surveillance are needed for the early detection of the pathogen and containment and mitigation of probable outbreaks. In this review, the main human arboviral diseases that emerged in Southern Europe are described.

“…A CCHFV strain, AP92, was isolated from Rhipicephalus bursa ticks collected in 1975 from goats in Vergina village in northern Greece [9]; the seroprevalence among 64 residents of Vergina was 6.1% [10]. In June 2008, CCHF emerged in Greece when a fatal case was observed in Komotini city (Rodopi prefecture) in north‐eastern Greece [11]. The causative strain (Rodopi strain) differs genetically from the AP92 strain, which is considered as non‐pathogenic or of low pathogenicity for humans [12].…”
Section: Univariate Logistic Regression Analysis Of Crimean‐congo Hamentioning
To estimate endemic areas for Crimean-Congo haemorrhagic fever (CCHF) in Greece, a country-wide seroepidemiological study was conducted, and 1611 human sera were prospectively collected along with data regarding possible risk factors for acquisition of infection, and tested for CCHF virus IgG antibodies by ELISA. The overall seroprevalence was 4.2%, with significant differences among prefectures, ranging from 0 to 27.5%. Multivariate analysis revealed that slaughtering and agricultural activities were significant risk factors for CCHFV seropositivity. The significantly high seroprevalence in specific prefectures, together with the extremely low number of CCHF cases, suggest that this phenomenon might be strain-related.
“…In a serosurvey conducted in Northern Greece, antibodies to R. conori were detected in 7.9% of the human population [10]. Here, we present a fatal MSF case in Northern Greece, which was initially considered to be one of Crimean–Congo haemorrhagic fever (CCHF): first, because the symptoms strongly resembled those of severe haemorrhagic fever and, second, because it was observed in the same region where the first confirmed Greek CCHF case was described, 45 days before [11], thus fulfilling the case definition for a probable CCHF case [12].…”
Forty-five days after the first confirmed and fatal Crimean-Congo haemorrhagic fever (CCHF) case in Greece in 2008, a female patient with similar signs and symptoms (high fever, thrombocytopaenia) and resident of the same area, was admitted to the University General Hospital of Alexandroupolis. Before admission, she had visited a local hospital where a cephalosporin was prescribed. A rash manifested over subsequent days, which was misdiagnosed as an allergy to the drug. Upon admission to the University Hospital, she was given further antibiotics, including doxycycline; a few hours later, ribavirin was added because CCHF was suspected. After the patient's death, rickettsiosis caused by Rickettsia conorii conorii (Meditteranean spotted fever; MSF) was diagnosed. Extremely high values of interleukin (IL)-1ra, IL-6, interferon-gamma-inducible protein-10, monocyte chemoattractant protein-1 and an absence of tumour necrosis factor-alpha were observed. MSF is a potentially severe and even fatal disease resembling viral haemorrhagic fevers that has to be included in the differential diagnosis of febrile syndromes combined with thrombocytopaenia, even when a tick bite is not reported, and an eschar is absent. Physicians have to be aware of MSF in patients with severe disease who are returning from the Mediterranean area.
