    Abstract Introduction: The non-endemic multicountry outbreak of monkeypox (MPX) has emphasized the issue of conspiracy theories that go viral in times of societal crisis. Now, it is the turn of MPX to join COVID-19 in the conspiracy theory realm. Social media outlets were flooded by a scourge of misinformation as soon as MPX cases began to appear with an evident cross-pollination between diverse conspiracy theories. Given the adverse consequences of conspiracy beliefs, this study aimed to assess the extent of endorsement of MPX conspiracy beliefs among the Lebanese population and to identify its associated factors.
    Methods: Using a convenience sampling technique, a web-based cross section was conducted among Lebanese adults. Data were collected using an Arabic self-reported questionnaire. Multivariable logistic regression was performed to identify the factors associated with the MPX conspiracy beliefs scale.
    Results: Conspiracy beliefs regarding emerging viruses including MPX were detected among 59.1% of Lebanese adults. Participants endorsed particularly the conspiracy theories linking the virus to a deliberate attempt to reduce the size of the global population (59.6%), gain political control (56.6%) or pharmaceutical companies' financial gain (39.3%), in addition to the manmade origin of MPX (47.5%). Remarkably, the majority of surveyed adults exhibited a negative attitude toward the government's preparedness for a potential MPX outbreak. However, a positive attitude was revealed toward the effectiveness of precautionary measures (69.6%). Female participants and those having a good health status were less likely to exhibit a higher level of conspiracy beliefs. On the contrary, divorced or widowed adults, those having a low economic situation, poor knowledge level, and negative attitude either toward the government or precautionary measures were more prone to disclose a higher level of conspiracy beliefs. Notably, participants relying on social media to get information about MPX were also more likely to have a higher level of conspiracy beliefs compared to their counterparts.
    Conclusions: The widespread extent of conspiracy beliefs endorsement regarding MPX among the Lebanese population urged the policymakers to find ways to reduce people's reliance on these theories. Future studies exploring the harmful impacts of conspiracy beliefs on health behaviors are recommended.

    Abstract Klebsiella pneumoniae is a Gram-negative bacterium that colonizes the gastrointestinal tract and nasopharynx with many being linked to nosocomial infections. Extended-spectrum β-lactamases (ESBL)-producing and carbapenem-resistant K. pneumoniae is recognized by the World Health Organization (WHO) as a critical public health concern. In this study, whole-genome sequencing (WGS) - based analysis was performed to understand the molecular epidemiology of multi-drug resistant Klebsiella spp. clinical isolates. Genome comparison, multi-locus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), and whole-genome-SNP-based phylogenetic analysis (wg-SNP) were used for in-depth molecular characterization. in silico typing was used to determine the resistance genes, virulence factors, Inc. groups, and capsular types. All except one isolate were non-susceptible to meropenem and 89% were non-susceptible to ertapenem and imipenem. bla

    Abstract Introduction: The ongoing multi-country outbreak of monkeypox (MPX) that emerges in non-endemic areas is a rare and unprecedented event that has sparked a widespread public health concern. Lebanon has reported four confirmed cases of MPX so far. Since good knowledge about the MPX virus and its associated disease is paramount for helping the Lebanese population prepare for a possible outbreak, therefore, it is important to assess their current level of knowledge regarding MPX and to identify its associated factors to highlight any knowledge gaps that need to be filled.
    Methods: An online cross-sectional study was conducted over the first 2 weeks of August 2022 among adults aged 18 years and above recruited from all Lebanese provinces using a convenience sampling technique. An anonymous, Arabic, self-reported questionnaire covering all main aspects of knowledge regarding MPX was developed and adapted based on the available literature. The Chi-square test was used to determine the associations between knowledge levels and independent variables including baseline characteristics. Multivariable logistic regression was also carried out on the significant variables in the bivariate analyses to identify the factors associated with the good knowledge level.
    Results: A total of 793 Lebanese adults participated in the study. The overall level of knowledge level regarding human MPX was poor among the Lebanese population; with only 33.04% of them having a good knowledge level ≥ 60%. Knowledge gaps and a substantial poor knowledge level were found in the majority of MPX knowledge domains especially those related to the routes of transmission (76.67%), clinical presentation and symptoms (71.63%), treatment (86.25%), and severity of the disease (91.3%). Interestingly, participants have a good knowledge level of the precautionary measures (80.45%), and the response to a suspected infection (65.20%). Female gender [(aOR = 0.870, CI 95% (0.613-0.941)], increased age 49 [aOR = 0.743, CI 95% (0.381-0.908)], and living in rural areas [aOR = 0.412, CI 95% (0.227-0.861)] were found negatively associated with a good level of knowledge. However, participants with higher educational levels [aOR = 1.243, CI 95% (1.032-3.801)], those working in the medical field [aOR = 1.932, CI 95% (1.331-3.419)], those suffering from chronic disease/immunodeficiency [aOR = 1.231, CI 95% (1.128-2.002)], and participants with moderate/high economic situations [aOR = 2.131, CI 95% (1.431-4.221)] were more likely to have a good knowledge score compared to their counterparts.
    Conclusions: The current study pointed out to poor knowledge level regarding MPX among the Lebanese population with substantial knowledge gaps in most aspects of MPX knowledge. The findings stress the urgent need to raise awareness and proactively fill the unveiled gaps, especially among less informed groups.

    Abstract The prevalence of antibiotic-resistant bacteria in surface water in Lebanon is a growing concern and understanding the mechanisms of the spread of resistance determinants is essential. We aimed at studying the occurrence of resistant bacteria and determinants in surface water sources in Lebanon and understanding their mobilization and transmission. Water samples were collected from five major rivers in Lebanon. A total of 91 isolates were recovered by incubating at 37°C on Blood and MacConkey agar out of which 25 were multi-drug resistant (MDR) and accordingly were further characterized. Escherichia coli and Klebsiella pneumoniae were the most common identified MDR isolates. Conjugation assays coupled with in silico plasmid analysis were performed and validated using PCR-based replicon typing (PBRT) to identify and confirm incompatibility groups and the localization of β-lactamase encoding genes. Escherichia coli EC23 carried a blaNDM-5 gene on a conjugative, multireplicon plasmid, while blaCTX-M-15 and blaTEM-1B were detected in the majority of the MDR isolates. Different sequence types (STs)were identified including the highly virulent E. coli ST131. Our results showed a common occurrence of bacterial contaminants in surface water and an increase in the risk for the dissemination of resistance determinants exacerbated with the ongoing intensified population mobility in Lebanon and the widespread lack of wastewater treatment.

    Abstract Enterobacter cloacae complex (ECC) members are rapidly emerging as successful nosocomial pathogens, especially, with the emergence of carbapenem-resistant clones. In this study, we performed a comprehensive molecular characterization of a carbapenem-resistant E. hormaechei ssp. xiangfangensis LAU_ENC1. hsp60 and average nucleotide identity (ANI) were used for its identification. The repertoire of resistance genes and phage content were analyzed. Plasmid sequences were extracted and compared to closest references. The isolate LAU_ENC1 was identified as an E. hormaechei ssp. xiangfangensis and belonged to ST-114A sub-cluster. bla

    Abstract Background: The COVID-19 pandemic has harshly burdened the healthcare systems. Health care workers (HCWs) are at substantial risk of infection and confronted several stressors as well leading them to experience burnout. This study aimed to assess the prevalence of burnout among Lebanese health HCWs and to identify its associated factors.
    Methods: A cross-sectional online survey was conducted between the first of November and the end of December 2020 among Lebanese HCWs working in all active hospitals operating across the country. Data were collected using an Arabic, anonymous, self-reported questionnaire comprising four sections: (a) basic sociodemographic characteristics, (b) exposure to COVID-19 covariates, (c) occupational factors, and (d) the measurements including the Copenhagen Burnout Inventory (CBI). CBI subscale cut-off score of 50 was used to assess the prevalence of burnout among HCWs. Multinomial logistic regression analyses were performed to examine the factors associated with the different aspects of burnout.
    Results: Out of the 1751 respondents, personal burnout (PB) was detected in its moderate and high-level aspects among 86.3% of Lebanese HCWs. Moderate and high levels of work-related burnout (WB), and client-related burnout (CB) hit 79.2% and 83.3% of HCWs, respectively. HCWs who were females, married, physicians, having a poor health status and specific living conditions (dependent child, elderly at home, family member with comorbidities, and a low income) were more likely to exhibit a high level of PB compared to no/low burnout level. Moreover, frontline HCWs, those infected by COVID-19 or those having a colleague infected by COVID-19, and those exhibiting a high perception of threat were more prone to experience a high-level PB rather than a low/no burnout. Working in a public hospital, extensive working hours, and insufficient sleeping hours were also found positively associated with high PB. However, older age and altruism were negatively associated with high PB compared to no/low PB among HCWs. As for WB, similar factors were found either positively or negatively associated with a high level of WB except health status and living conditions factors (dependent child or family member). As for CB, older age of HCWs (> 30 years) and altruism were negatively associated with high CB compared to no/low burnout level. However, working in the frontline, high threat perception, extensive working hours, insufficient sleeping hours, and low income were positively associated with high CB among HCWs compared to no/low burnout.
    Conclusion: The prevalence of burnout among Lebanese HCWs during the pandemic was significant and alarming. Enacting and implementing preventive policies and effective interventions are urgently needed to cultivate wellness among HCWs.

    Abstract Background and objective Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) are rapidly emerging worldwide. This study aimed to assess the effect of contact precaution (CP) on ESBL-PE-colonization rates among nurses in three hospitals in Beirut, Lebanon, where ESBL is endemic, in order to define the risk factors for colonization. Accordingly, the ongoing use of CP to prevent ESBL-PE transmission to healthy nurses was evaluated. Methods This cross-sectional study was conducted in three hospitals. Hospital 1 required CP, Hospital 2 had recently stopped CP, and Hospital 3 had stopped it three years previously. Questionnaires and stool-collection containers were distributed to all patient care nurses in those three hospitals. The Returned samples were tested using the agar dilution technique. Results A total of 269 out of 733 nurses volunteered to participate; 140 met the inclusion criteria (no recent hospitalization, antibiotic use, or known ESBL-PE colonization) and provided samples. Among them, 15% were ESBL-positive. Compared to nurses from Hospital 3, nurses from Hospital 1 were 59% less likely to be colonized, while nurses from Hospital 2 were 62% more likely to be colonized. Conclusion In hospitals where CP is in place for ESBL-positive patients, ESBL-PE prevalence in nursing staff was significantly lower. Additionally, a work experience of two to four years increased the odds of ESBL-PE colonization in comparison with longer nursing experience. CP may be a justifiable means of protection against ESBL-PE transmission to healthy nurses. The risk factors for colonization were discontinuation of CP and a shorter clinical work experience.

    Abstract Introduction: While the widespread implementation of the non-pharmaceutical interventions was intended to contain the COVID-19 pandemic, such measures could be also effective in limiting the spread of other respiratory infections. This study aimed to examine the association between the implementation of personal protective measures and the occurrence of influenza-like illnesses (ILI) in the general population.
    Methods: An online retrospective cross-sectional observational study was conducted in April 2021 to assess cases of ILI among Lebanese adults aged 18 years and above, from all Lebanese governorates during the 2020-2021 flu season. Data were collected using a convenience sampling method. In addition to their socio-demographic information, participants were asked about their frequency of implementing personal protective measures and if they have experienced symptoms of ILI in the previous 6 months. The overall score of the personal protective measures was computed. Multivariable logistic regression was performed to examine the association between participants' level of adoption of personal protective measures against COVID-19 and the occurrence of ILI.
    Results: Among the 1019 Lebanese adults participating in this study, 352 (34.54%) of them reported symptoms of ILI between October 2020 and March 2021. Lebanese adults who wore their facemasks frequently or always were less likely to suffer from symptoms of ILI than others who did not wear the mask (aOR = 0.452, 95% CI = 0.349-0.693, p < 0.001). Similarly, adults who adopt the following protective measures washing hands (aOR = 0.608, 95% CI = 0.524-0.922, p < 0.001), respecting cough etiquette (aOR = 0.763, 95% CI = 0.598-0.918, p < 0.001), disinfecting surface (aOR = 0.892, 95% CI = 0.632-0.911, p = 0.012), avoiding crowded places (aOR = 0.739, 95% CI = 0.688-0.903, p = 0.049), respecting physical distancing (aOR = 0.646, 95% CI = 0.482-0.833, p = 0.031) on a regular basis (frequently/always) were less likely to report symptoms of influenza-like illnesses when compared with those who did not adhere at all to these measures.
    Conclusion: Our study highlighted the potential of personal protective measures against COVID-19 in reducing the transmission of respiratory infections such as ILI. Such findings might be invested during influenza season, particularly among groups at high risk of developing severe complications. Exploring trends detected by the national severe acute respiratory infection surveillance system is recommended to confirm the utility of these measures.

    Abstract Acute diarrhea is a prevalent disease worldwide and a cause of mortality in low and middle-income countries. In previous studies, the causative enteropathogen is found in 38% to 58% of patients, leaving a considerable diagnostic gap. In this study, we intend to determine the pathogenic agents responsible for acute diarrhea in patients presenting to the Emergency Departments of several Lebanese hospitals. A total of 100 stool samples were collected between June 2022 and June 2023 from patients presenting with acute diarrhea to the Emergency Departments. Pathogens were detected by multiplex polymerase chain reaction. The average age for the patients was 53 years old. All patients presented with diarrhea, 15 of them had fever associated. In total, 46 patients were admitted to the hospital (70%), among them 80% received Intravenous antibiotics. Campylobacter was the most common agent detected in 36%, followed by Rotavirus 19%, and Noroviruses 15%. The rest was detected at lower percentages. Bacteria accounted for 49% of cases, viruses for 39%, and parasitic infection 6%. Acute diarrhea epidemiology is understudied in Lebanon. This study is the first Lebanese data about acute diarrhea pathogens. Avoiding overuse of antibiotics in bacterial versus viral infections can be achieved while prevention campaigns can raise awareness about food and water safety at the community level.

    Abstract Enterobacter cloacae complex (ECC) members are rapidly emerging as successful nosocomial pathogens, especially, with the emergence of carbapenem-resistant clones. In this study, we performed a comprehensive molecular characterization of a carbapenem-resistant E. hormaechei ssp. xiangfangensis LAU_ENC1. hsp60 and average nucleotide identity (ANI) were used for its identification. The repertoire of resistance genes and phage content were analyzed. Plasmid sequences were extracted and compared to closest references. The isolate LAU_ENC1 was identified as an E. hormaechei ssp. xiangfangensis and belonged to ST-114A sub-cluster. blaNDM₋₁, blaCTX₋M₋₁₅, blaOXA₋₁, and blaACT₋₁₆ genes were detected as β-lactam resistance determinants. A chromosomal hybrid intact phage, Enterobacter phage LAU1, with blaCTX₋M₋₁₅ integrated in its direct vicinity within an ISEcp1 - blaCTX₋M₋₁₅ - wbuC - ∆Tn2 rare cassette was detected. blaNDM₋₁ was integrated within a novel IncFII conjugative plasmid, pLAU_ENC1, through an IS3000- ΔISAba125-blaNDM₋₁-bleMBL−//−Tn5403 cassette. To our knowledge, this is the first report of a multi-drug resistant (MDR) E. hormaechei ssp. xiangfangensis carrying a blaCTX₋M₋₁₅ integrated within the proximity of a provirus chromosomal region. Treatment options for MDR ECC members are becoming scarce, thus warranting an increased monitoring of the dissemination of these pathogens in clinical settings.
