There has been an increase in reported TBE cases in Europe since 2015, reaching a peak in some countries in 2020, highlighting the need for better management of TBE risk in Europe. TBE surveillance is currently limited, in part, due to varying diagnostic guidelines, access to testing, and awareness of TBE. Consequently, TBE prevalence is underestimated and vaccination recommendations inadequate. TBE vaccine uptake is unsatisfactory in many TBE-endemic European countries. This review summarizes the findings of a scientific workshop of experts to improve TBE surveillance and vaccine uptake in Europe. Strategies to improve TBE surveillance and vaccine uptake should focus on: aligning diagnostic criteria and testing across Europe; expanding current vaccine recommendations and reducing their complexity; and increasing public education of the potential risks posed by TBEV infection.
The importance of studies on the diversity of ticks attacking humans resides mostly in the relatively highly-specific tick-pathogen associations. Human tick bites are commonly reported worldwide but removal of ticks from patients is rarely followed by specific identification of the ticks, leaving to some degree of hazard the preventive treatment of possible associated diseases. A total number of 308 ticks were collected between April and June 2010 from 275 human patients who voluntarily presented to a hospital from Cluj-Napoca, Romania. The mean intensity of infection was 1.12 ± 0.46. Four species of ticks were identified Ixodes ricinus, Dermacentor marginatus, Haemaphysalis concinna and H. punctata. Ixodes ricinus was the most abundant species feeding on humans in the study area. A brief review of possible associated pathogen is provided.
Introduction: West Nile virus (WNV), Usutu virus (USUV), and the tick-borne encephalitis virus (TBEV) are all arboviruses belonging to Flaviviridae family. All are characterized by vectorial transmission and sometimes associated with neuroinvasive infections. The circulation of these viruses is considered endemic in parts of Europe, with human cases reported in many countries. Among hosts, the viruses are vectored by hematophagous arthropods, such as mosquitoes (WNV, USUV) and ticks (TBEV). Considering the currently outdated knowledge regarding the epidemiology of these viruses in Romania, the aim of our study was to assess the seroprevalence rates of WNV, USUV, and TBEV among healthy blood donors in north-western Romania. Methods: Human blood samples from healthy donors were collected between November 2019 and February 2020 in six counties from the north-western region of Romania. The samples were serologically tested by ELISA and serum neutralization test. Results: Overall, we obtained a seroprevalence of 3.17% for WNV, 0.08% for TBEV, and 0% for USUV. Conclusion: Despite the low seroprevalence of WNV, USUV, and TBEV in our study, we highlight the need for continuous nationwide vector and disease surveillance and implementation of control measures. Further research is required for an optimal overview of the epidemiological status of the Romanian population regarding these flaviviruses together with countrywide awareness campaigns.
Early diagnosis of travel-imported cases is important to reduce the risk of localized outbreaks of tropical arboviruses such as dengue and chikungunya and the risk of local transmission from body fluids or vertical transmission. Given the global relevance of arboviruses and the continuous risk of (re)emerging arbovirus events, clinicians should be aware of the clinical syndromes of arbovirus fevers and the potential pitfalls in diagnosis.
The COVID-19 pandemic put unprecedented pressure on all areas of activity, especially healthcare workers. Understanding the psychological response to the pandemic in healthcare workers is an important challenge. This study aims to investigate burnout, depression, and job stress factors in the medical personnel of a COVID-19-dedicated hospital, two years after the beginning of the pandemic. The survey was performed between the fifth and sixth pandemic waves in Romania. Employees of the Clinical Hospital for Infectious Diseases, Cluj-Napoca, completed an online survey using four tools: Maslach Burnout Inventory (MBI), Copenhagen Burnout Inventory (CBI), the Karasek Job factors questionnaire, and the Patient Health Questionnaire–9 (PHQ-9). A total of 114 employees completed the questionnaire (10.83% of total employees). The results showed 100% prevalence of Maslach burnout (56.1% moderate and severe burnout) and 63.1% prevalence of depression. The infectious disease resident doctors had the highest prevalence of burnout scores, depression, and perceived Karasek job demands. The 22- to 30-year-old age group and the group with fewer than ten years of professional experience had a significantly higher prevalence of burnout and depression than older employees or employees with more professional experience. The COVID-19 pandemic continues to have a high impact on the mental health of healthcare workers.
Background: We aimed to externally validate three prognostic scores for COVID-19: the 4C Mortality Score (4CM Score), the COVID-GRAM Critical Illness Risk Score (COVID-GRAM), and COVIDAnalytics. Methods: We evaluated the scores in a retrospective study on adult patients hospitalized with severe/critical COVID-19 (1 March 2020–1 March 2021), in the Teaching Hospital of Infectious Diseases, Cluj-Napoca, Romania. We assessed all the deceased patients matched with two survivors by age, gender, and at least two comorbidities. The areas under the receiver-operating characteristic curves (AUROCs) were computed for in-hospital mortality. Results: Among 780 severe/critical COVID-19 patients, 178 (22.8%) died. We included 474 patients according to the case definition (158 deceased/316 survivors). The median age was 75 years; diabetes mellitus, malignancies, chronic pulmonary diseases, and chronic kidney and moderate/severe liver diseases were associated with higher risks of death. According to the predefined 4CM Score, the mortality rates were 0% (low), 13% (intermediate), 27% (high), and 61% (very high). The AUROC for the 4CM Score was 0.72 (95% CI: 0.67–0.77) for in-hospital mortality, close to COVID-GRAM, with slightly greater discriminatory ability for COVIDAnalytics: 0.76 (95% CI: 0.71–0.80). Conclusion: All the prognostic scores showed close values compared to their validation cohorts, were fairly accurate in predicting mortality, and can be used to prioritize care and resources.
No outcome differences were found between the group of patients bitten by B. burgdorferi positive ticks and the group of patients bitten by B. burgdorferi negative ticks.
