RESUMO
OBJECTIVES: According to current knowledge about legionella transmission, healthcare workers (HCWs) are at an increased risk of exposure. The aim of this research was to systematically review the literature about HCWs' exposure to legionella and establish whether there is an occupational risk. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: PubMed, Scopus and Web of Science were searched to identify studies regarding the occupational risk of legionellosis for HCWs. Keywords used in the search were 'Legionella pneumophila', 'occupational medicine', 'occupational' and 'risk'. Selected studies were reviewed to assess the quality and meta-analysed. Finally, the nine epidemiological principles of Bradford-Hill criteria were used to assess whether legionellosis could be considered an occupational risk for HCWs. RESULTS: The search strategy retrieved 124 studies, and 10 studies were included in the present review. The overall study quality was low. The pooled odds ratio estimate was 2.45 (95% confidence interval: 1.52-3.96). The assessment using Bradford-Hill criteria showed that only two criteria (plausibility and coherence) were met, which is insufficient to establish an occupational risk. CONCLUSIONS: This systematic review suggests that there is a higher risk of legionella exposure for HCWs, but there is currently no clinical evidence. Further studies with appropriate study design are needed to determine whether legionella infection is an occupational risk for HCWs.

Methods: A questionnaire of 36 questions was developed and administered to assess socio-occupational characteristics, knowledge of Healthcare-associated infections, attitudes and barriers encountered in compliance with hygiene standards, self-analysis of professional behaviour, and proposals for new interventions. Variables were evaluated by univariate analysis, and multivariable logistic regression models were constructed to identify predictors of adequate knowledge, positive attitude and appropriate professional behaviour. Background: Healthcare-associated infections are the main complications of hospitalization. A bottom-up approach, where the Healthcare workers involved play a key role, can be adopted to limit the Healthcare-associated infections burden. To this end, a survey was conducted in the main intensive care unit of Umberto I Teaching Hospital of Rome, where an active surveillance system has been in place since April 2016. Results: Overall, 79/89 Healthcare workers completed the questionnaire. Multivariate analysis showed that Healthcare workers, who participated in ward meetings to share active surveillance reports, were more likely to have adequate knowledge (aOR=4.21, 95% CI: 1.36-13.07). Only job type seemed to be a predictor of adequate behaviour, since nurses and physicians were more likely to show adequate behaviour than residents in training (aOR=0.21, 95% CI: 0.06-0.74). Direct observation of compliance with standard hygiene precautions and the identification of 'local champions' to manage Healthcare-associated infections' issues were the most requested interventions. Conclusions: Our study suggests that the training of healthcare professionals is a key factor in preventing and containing the spreading of Healthcare-associated infections. Moreover, by encouraging greater Healthcare workers' involvement, we conclude that a bottom-up approach is likely to improve Healthcare-associated infections' prevention and management.

BACKGROUND: Hospital acquired infections have been associated with the contamination of flexible endoscopes caused by a failure of the reprocessing procedure. Microbiological surveillance of endoscope reprocessing is valuable for assessing contamination by pathogens. The aim of this study is to evaluate microbiological contamination of endoscopes after reprocessing, and the involvement of reprocessing procedures adopted in endoscopy units of an Italian teaching-hospital. METHODS: The study was carried out, on several dates in 2014, in 11 endoscopic operation units equipped with 100 endoscopes (18 bronchoscopes, 41 gastroduodenoscopes, 29 colonoscopes, 12 laryngoscopes) and 9 Automated Endoscope Reprocessors. Presence/absence of common pathogens and indicator micro-organisms (including multi-drug resistant bacteria) and Total Microbiological Count (TMC) were obtained from the biopsy channels of endoscopes after reprocessing, from final rinse water of automated endoscope reprocessors and from tap water applying standard microbiological culture methods. Following the European Guidelines for quality assurance in reprocessing, the post-reprocessing criteria were "absence of indicator micro-organisms and absence of TMC in samples obtained from endoscopes' channels". RESULTS: A total of 180 samples were collected (143 endoscopes, 25 Automated Endoscope Reprocessors and 12 water supply). Compliance to the European Guidelines was achieved for 112 out of the 180 (62.2%) samples analyzed. Presence of indicator micro-organisms (mainly Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa and other Gram-negative non-fermenting bacteria) was found in 51 out of 143 endoscopes (35.7%). Multi-drug resistant bacteria were also found. Presence of pathogen micro-organisms was statistically associated with the increase of TMC level, but not with time after reprocessing. CONCLUSION: The study provides information about the microbiological quality of endoscope reprocessing procedures adopted by different endoscopic operation units. The high prevalence of contaminated endoscopes provides evidence of the need to improve the quality of reprocessing.

BACKGROUND: Healthcare-associated infection (HAI) is the most frequent adverse event in healthcare settings. It is associated with increased mortality and antimicrobial resistance, leading to prolonged hospital stays and consistent financial loss for healthcare systems. The objective of this study was to estimate the burden of HAIs and antimicrobial use in the Teaching Hospital Policlinico Umberto I (THPUI) of Rome and to identify the most critical areas for intervention. METHODS: Data were collected according to the most recent ECDC point prevalence survey protocol in November 2018. Descriptive statistics for all variables were calculated. Univariate analysis was used to assess possible associations between variables and HAIs. Variables with a significance level of p<0.25 were included in a multiple logistic regression model. RESULTS: A total of 799 patients were included in the analysis; of these, 13.3% presented with at least one HAI. Bloodstream infection was the most common, accounting for 30.9% of total infections. Overall, 125 microorganisms were isolated, with Enterobacteriaceae being the most frequent (32%). At the time of the survey, 49.1% patients were receiving antimicrobial therapy. The multivariate analysis showed a significant association between HAI and use of medical devices (OR=34.30; 95% CI:3.69-318.66), length of stay (OR=1.01; 95% CI:1.00-1.02) and exposure to prophylactic antimicrobial therapy (OR=0.23; 95% CI:0.11-0.47). CONCLUSIONS: The ECDC methodology proved to be applicable to THPUI, where HAI prevalence was higher than the European standard (6.7%). This highlights the need to implement targeted measures to prevent and control HAIs, including continuous monitoring to evaluate the effectiveness of such interventions.

BACKGROUND: Healthcare-associated infections (HAIs), or nosocomial infections, represent a significant burden in terms of mortality, morbidity, length of stay and costs for patients hospitalized in intensive care units (ICUs). Surveillance systems are recommended by national and international institutions to gather data on HAIs in order to develop and evaluate interventions that reduce the risk of HAIs. STUDY DESIGN: Here we describe the methodology and the results of the surveillance system implemented in the ICU of the Policlinico Umberto I, a large teaching hospital in Rome, from April 2016 to October 2018. METHODS: The multimodal infection surveillance system integrates four different approaches: i) active surveillance of inpatients; ii) environmental microbiological surveillance; iii) surveillance of isolated microorganisms; and iv) behavioral surveillance of healthcare personnel. Data were collected on catheter-related bloodstream infections, ventilation-associated pneumonia, catheter-associated urinary tract infections and primary bloodstream infections that developed in patients after 48 h in the ICU. For environmental surveillance 14 points were selected for sampling (i.e. bed edges, medication carts, PC keyboards, sink faucets). The system of active surveillance of HAIs also included surveillance of microorganisms, consisting of the molecular genotyping of bacterial isolates by pulsed-field gel electrophoresis (PFGE). From 1 November 2016, monitoring of compliance with guidelines for hand hygiene (HH) and proper glove or gown use by healthcare personnel was included in the surveillance system. After the first six months (baseline phase), a multimodal intervention to improve adherence to guidelines by healthcare personnel was conducted with the ICU staff. RESULTS: Overall, 773 patients were included in the active surveillance. The overall incidence rate of device-related HAIs was 14.1 (95% CI: 12.2-16.3) per 1000 patient-days. The monthly device-related HAI incident rate showed a decreasing trend over time, with peaks of incidence becoming progressively lower. The most common bacterial isolates were Klebsiella pneumoniae (20.7%), Acinetobacter baumannii (17.2%), Pseudomonas aeruginosa (13.4%) and Staphylococcus aureus (5.4%). Acinetobacter baumannii and Klebsiella pneumoniae showed the highest proportion of isolates with a multidrug-resistant profile. A total of 819 environmental samples were collected, from which 305 bacterial isolates were retrieved. The most frequent bacterial isolates were Acinetobacter baumannii (27.2%), Staphylococcus aureus (12.1%), Enterococcus faecalis (11.1%), Klebsiella pneumoniae (5.2%) and Pseudomonas aeruginosa (4.7%). All Acinetobacter baumannii, Pseudomonas aeruginosa and Klebsiella pneumoniae environmental isolates were at least multidrug-resistant. Genotyping showed a limited number of major PFGE patterns for both clinical and environmental isolates of Klebsiella pneumoniae and Acinetobacter baumannii. Behavioral compliance rates significantly improved from baseline to post-intervention phase. CONCLUSIONS: By integrating information gathered from active surveillance, environmental microbiological surveillance, surveillance of bacterial isolates and behavioral surveillance of healthcare personnel, the multimodal infection surveillance system returned a precise and detailed view of the infectious risk and microbial ecology of the ICU.

BACKGROUND: In this study we estimated the presence of Legionella species, viable but non-culturable (VBNC), in hospital water networks. We also evaluated the time and load of Legionella appearance in samples found negative using the standard culture method. METHODS: A total of 42 samples was obtained from the tap water of five hospital buildings. The samples were tested for Legionella by the standard culture method and were monitored for up to 12 months for the appearance of VBNC Legionella. RESULTS: All the 42 samples were negative at the time of collection. Seven of the 42 samples (17.0%) became positive for Legionella at different times of monitoring. The time to the appearance of VBNC Legionella was extremely variable, from 15 days to 9 months from sampling. The most frequent Legionella species observed were Legionella spp and L. anisa and only in one sample L. pneumophila srg.1. CONCLUSIONS: Our study confirms the presence of VBNC Legionella in samples resulting negative using the standard culture method and highlights the different time to its appearance that can occur several months after sampling. The results are important for risk assessment and risk management of engineered water systems.

BACKGROUND: To investigate dietary habits among young people in the Mediterranean lands, exactly where the health benefits of the Mediterranean diet (MD) were discovered by Ancel Keys. STUDY DESIGN: A cross-sectional study design. METHODS: A 10-items food-frequency questionnaire was administered to 1117 students in the schools of the Cilento area. Adherence to the MD was appraised according to a scale of 0-10. A logistic regression model was used to identify possible factors associated with "Following an unhealthy diet". Results were expressed as Odds Ratio with 95% confidence interval and the level of significance was set at p<0.05. RESULTS: A percentage of 63.8 reached a score under six, indicating that the majority of the students did not respect the rules of the Mediterranean diet and only 36.2% (n. 371) exceeded a score of 6 adhering to it in varying degrees. At the logistic regression analysis smokers resulted to be affected by almost a double risk of getting away from the Mediterranean dietary pattern (OR = 1.93; CI 95% 1.44-2.57); on the contrary, those with a higher PCS12 (Physical Component Summary score) were in a lower risk to move away from the MD style (OR = 0.98; 95% CI = 0.96-0.99). CONCLUSIONS: Despite its increasing popularity worldwide, adherence to the MD model is decreasing. The new generation of young people does not adhere to the MD pattern although they live in the lands characterized by the tradition and culture of healthy diet and where the benefits from this pattern were initially discovered. Interventions and specific education about the healthy diet may be useful to recover student's dietary patterns as in the old eating tradition.

During the school years 2009-2010 and 2010-2011 a total of 25 cases of Non Tuberculous Cutaneous Mycobacteriosis (NTCM) were notified in children attending the same school with a swimming pool in Rome. Environmental microbiological and epidemiological investigations (only for suspected outbreaks in 2009-2010) were conducted. We screened students with skin lesions, and environmental samples were collected from the school area and the swimming pool. During the school year 2009-10 18 cases were clinically identified among 514 primary school children (3.50%) and all cases attended the swimming pool. Only 2 out of 18 cultures were positive for Mycobacterium chelonae complex (Group III, M. abscessus). Attack Rate for swimming pool use was 13,10% (17/130), with a Relative Risk 54,70 (95% CI: 9,4 - ∞). In February 2011 additional 7 cases of cutaneous NTM among children - who attended the same primary school and swimming pool were notified to the local public health authority followed by environmental microbiological investigation. Environmental samples were positive for NTM but not for M. abscessus. Mycobacteria are not included in water-quality criteria in Italy for this reason it is important to collect evidences of NTM cases caused by these infrequent pathogens, to be able to perform rapid risk assessment and to identify the best practices in prevention and management of such a risk.

This study was performed to characterize and quantify mould and yeast isolates in fresh vegetables (FV) and ready to eat salads (RTES). During 2007, a random set of 194 samples, including 56 samples of FV and 138 samples of RTES, were analyzed for a total of 388 mycological determinations. Yeasts and moulds identification was carried out on 18/56 whole FV and 42/138 RTES. Yeasts were the predominant organisms in the FV (mean values: 6.20 log cfu g-1-8.00 log cfu g-) while moulds showed lower mean values (4.70 log cfu g-l-6.79 log cfu g-l). After processing, FV samples showed a statistically significant decreases (p-value <0.001) in the contamination of fungi. Most of the species identified were found both in the FV and RTES samples. Many of moulds species isolated belong to toxigenic genera Penicillium, Stachybotrys, Phoma, Fusarium indicating a potential mycotoxin production and a potential risk for consumers.

The Authors report three cases of ophthalmic neurosyphilis in patients who complained a visual decrease monocular. The diagnosis was performed with physical and fundus examination, electrophysiological, hemato-chemical and microbiological tests, fluorangiografy and RMN. The physical examination provided standard results about eyes interested while the fundus examination, as well as the electrofunctional and fuorangiografy examinations, showed some alterations. The sockets and encephalon RMN were normal. Moreover; the patients were submitted to specific haematic and microbiological laboratory tests which showed positivity for syphilis. To sum up all patients received an incidental diagnosis of syphilis. This trend could be attributable to an extensive use of antibiotics that changing the natural course of disease, mask clinical evidences and make them harder to diagnose.

Appropriate, timely, and data-driven health information is a very important issue in preventive strategies against influenza. Intuitively, a link between willingness to be vaccinated against seasonal influenza and against pandemic influenza exists, given the similarities in decision-making for this vaccine. International and national literature reviews suggest that progress has been made in order to incorporate and disseminate crisis risk communication principles into public health practice, as such investments in public health could be important for building capacity and practice which aid in the realization of countermeasures in response to a future pandemic and epidemic situation. This study emphasizes the lack of perception by Health Care Workers (HCWs) of the importance of being immunized against seasonal and pandemic influenza and the doubts concerning safety. In the future, particular efforts are needed during vaccination campaigns, to provide more information to HCWs and the general population regarding role and safety of such vaccines.

Research on quality of surface waters has been performed also in Italy during the development of the large urban areas, and in Rome this has been the duty of the Istituto di Igiene of the Sapienza University since 1890. Using MedLine--and also traditional consultation for papers printed before 1968--we identified 100 articles printed in the period 1890-2010. Thirty of them met the inclusion criteria (to have been written by researchers belonging to the Rome universities and to contain microbiological informations about the surface waters of Rome). The majority of papers identified (46.6%) were produced during the years Sixties and Seventies of the 20th century, and 30% in the twenty years to follow (1980-1999). The most frequent microbiological descriptors were "Total coliforms" and "Streptococci". The waterbodies most investigated were the Tiber river and the coastal waters around Fiumicino, where the Tiber flows into the Tyrrhenian sea. The quality of surface waters has always been a central interest of the research performed by the Hygienists of the Roman School. The good quality of the past research and the renovated interest of International Organizations and of the European Union should encourage the public health researchers toward a strategic field of investigation which has strong interconnections with the protection of the individual and community health and also with the protection of the environment.

BACKGROUND: During the intensive care units' (ICUs) reorganization that was forced by the COVID-19 emergency, attention to traditional infection control measures may have been reduced. Nevertheless, evidence on the effect of the COVID-19 pandemic on healthcare-associated infections (HAIs) is still limited and mixed. In this study, we estimated the pandemic impact on HAI incidence and investigated the HAI type occurring in COVID-19 patients. METHODS: Patients admitted to the main ICU of the Umberto I teaching hospital of Rome from March 1st and April 4th 2020 were compared with patients hospitalized in 2019. We assessed the association of risk factors and time-to-first event through multivariable Fine and Grey's regression models, that consider the competitive risk of death on the development of HAI (Model 1) or device related-HAI (dr-HAI, Model 2) and provide estimates of the sub-distribution hazard ratio (SHR) and its associated confidence interval (CI). A subgroup analysis was performed on the 2020 cohort. RESULTS: Data from 104 patients were retrieved. Overall, 59 HAIs were recorded, 32 of which occurred in the COVID-19 group. Patients admitted in 2020 were found to be positively associated with both HAI and dr-HAI onset (SHR: 2.66, 95% CI 1.31-5.38, and SHR: 10.0, 95% CI 1.84-54.41, respectively). Despite being not confirmed at the multivariable analysis, a greater proportion of dr-HAIs seemed to occur in COVID-19 patients, especially ventilator-associated pneumonia, and catheter-related urinary tract infections. CONCLUSIONS: We observed an increase in the incidence of patients with HAIs, especially dr-HAIs, mainly sustained by COVID-19 patients. A greater susceptibility of these patients to device-related infections was hypothesized, but further studies are needed.

AIMS: The study was performed to evaluate the safety of whole and RTE vegetables and to investigate the effectiveness of different preventive strategies for the quality assurance of RTE vegetables collected from three Italian production systems. Producer 1, applied a strict system in compliance with GAP- GMP - HACCP, Producer 2 used chlorine disinfection at a second washing step, and Producer 3 using a physical microbial stabilization. METHODS: During the period 2005-2007, a total of 964 samples including whole vegetables and RTE salads, collected from three different producers in central Italy, were analysed to quantify the aerobic mesophilic count (AMC) and Escherichia coli, and for the presence of Salmonella spp, Listeria monocytogenes, E. coli O157:H7, hepatitis A virus and Norovirus (NoV). RESULTS: None of the whole vegetable samples were positive for L. monocytogenes, E. coli O157:H7, HAV and NoV; however, a low prevalence of Salmonella was found. No pathogens were detected with cultural methods in any of the RTE vegetables analysed, only two RTE samples were positive for L. monocytogenes with PCR, but were not confirmed by the cultural method. The median values of AMC in RTE vegetables measured 24 h after packaging were statistically different among the 3 producers (5·4 × 10(6), 1·5 × 10(7) and 3·7 × 10(7) CFU g(-1), respectively; P=0·011). The lowest level was detected in Producer 1. CONCLUSION: The products that were processed applying rigorously GAP, GMP and HACCP showed a better microbiological quality than those processed with chemical or physical stabilization. STUDY SIGNIFICANCE AND IMPACT: The results of the study evidenced the efficacy of GAP, GMP and HACCP in improving microbiological quality of whole and RTE vegetables.

BACKGROUND: Disability Management can be defined as a practice to improve workers' health and to reduce the impact and costs of disability. The aim of the study was to estimate the diffusion of DM in Italian companies. METHODS: A survey was conducted using a questionnaire, the Worksite Disability Management Audit. The questionnaire was structured into five parts addressing the following domains: 1) characteristics of the company; 2) health promotion activities; 3) preventive measures; 4) case management; 5) disability management. We selected public and private companies and collected information by direct interview. RESULTS: Twenty companies entered the survey. Twelve Companies (60%) indicated that health promotion programs and sensibilisation campaigns are usually carried out. The presence of an individual who provided workplace safety indications and materials was stated by 19 companies (95%). Periodical medical examinations are carried out by 19 companies (95%); 16 (80%) have an evaluation process for ergonomics concerns. Risk assessment and analysis are performed by all companies and the security procedures and policies are updated at least once in a year in 40% of cases. Health status monitoring of injured workers is performed in eight (40%) of the companies, while Disability Management is present as a whole in only three companies. CONCLUSIONS: This survey highlights that Disability Management is not undertaken in most companies and that, where applied, there is still confusion and disorganization about ways to promote health and manage workers' illness and disability. Hence, there is still the need to promote an all-inclusive evaluation and management of workers' safety, illness and disabilities.

BACKGROUND: Stroke is the most common cardiovascular disorder after heart disease and one of the major causes of death and disability. Mediterranean diet has proven to be an effective means to prevent cardiovascular diseases and may contribute to the prevention of stroke. This overview aims to analyze all reviews that examine the association between Mediterranean diet pattern and stroke. METHODS: We conducted a literature search on PubMed and Scopus databases, using the keywords "Mediterranean diet" and "Stroke". All studies were selected evaluating the association between the Mediterranean diet and the prevention of stroke and only systematic reviews, meta-analysis and narrative reviews were included. RESULT: 25 eligible articles were included (16 narrative reviews, 9 systematic reviews, 6 systematic reviews with meta-analyses). The authors stated that Mediterranean diet may be a useful means of preventing stroke, especially the 6 meta-analyses highlighted that high adherence to Mediterranean diet was protective against stroke, with a relative risk ranging from 0,64 (95% CI 0,48-0,88) to 0,90 (95% CI 0,87-0,93). Moderate adherence has not shown significant results. CONCLUSION: A high adherence to the Mediterranean diet is inversely associated with stroke risk, and can modify the costs of its management, therefore the prevention policies should implement adherence to this healthy diet.

Antibiotic resistant bacteria (ARB) have been found on fresh fruit and vegetables globally. These types of ARB infections are spreading rapidly and are a major human health threat. A quantitative human exposure assessment model was created using scenario analysis to investigate the potential human exposure to antibiotic resistant Escherichia coli (AR-E. coli) through the consumption of lettuce irrigated with surface water. Scientific literature and site specific data were collected to model each process from farm to fork to calculate the concentration of AR-E. coli on the lettuce at the point of human consumption. The processes examined were the adhesion, colonisation and viability of bacteria on the lettuce; the effect of different post-harvest cleaning processes; the effect of consuming the lettuce before, on or after the expiry date; and the effect of the consumer washing the lettuce. The results show the mean human exposure levels ranged between 1.00â¯×â¯10-2 and 1.35â¯×â¯106â¯colonyâ¯formingâ¯units (CFU) of AR-E. coli per 100â¯g of surface water irrigated lettuce for the different scenarios investigated. The mean probability of illness from consuming 100â¯g of lettuce contaminated with potential pathogenic antibiotic-sensitive E. coli was between 1.46â¯×â¯10-9 to 1.88â¯×â¯10-2. A back calculation revealed that in order for the EC No 1441/2007 regulation to be exceeded (≥1000â¯CFU/g of E. coli on lettuce at the manufacturing stage), the mean contamination levels required in the irrigation water would need to be 2.7, 3.1 or 4.8â¯logâ¯CFU/ml using the post-harvest treatments of washing with water, rapid cooling with water and washing with a chlorine solution respectively. The information generated from this model could help to set guidelines for producers on maximum permissible AR-E. coli contamination levels in irrigation water and provides recommendations on the best post-harvest treatment to use.

BACKGROUND ADN AIM: Healthcare workers and Biomedical students are continuously exposed to biological risk in their clinical practice. The objective of this study was to evaluate the validity and reliability of an Italian questionnaire on the knowledge and perception of biological risk in Biomedical students at the beginning of their professional training. MATERIALS AND METHODS: An electronic questionnaire was administered to students attending the second semester of the first year of Biomedical Courses at Sapienza University of Rome. The questionnaire consists of 40 questions divided into five sections collecting sociodemographic data, health status and level of knowledge and perception of biological risk. The statistical analysis was performed with Statistical Package for Social Sciences (SPSS) version 25. RESULTS: A total of 309 individuals answered the online questionnaire, with a response rate of 83.5%. The analysis of internal consistency was performed by two dichotomous variables that measured the knowledge level on hygiene behaviour and gloves use. The analysis showed a standardized Cronbach's alpha equal to 0.765, corresponding to a good reliability. A better reliability was found out among physiotherapy and medical students, with a Cronbach's alpha equal to 0.944 and 0.881, respectively. Regarding vaccines, 97.7% of the sample was given a Hepatitis B vaccination and 98.7% of students consider vaccinations essential for healthcare workers. CONCLUSIONS: Results of Cronbach's alpha showed a good reliability of the questionnaire. First-year Biomedical students may be exposed to occupational biological risk mainly because of their inexperience. A training educational path should be implemented in order to acquire competences, knowledge, attitudes and practical skills, correct behaviors and a personal and professional responsibility.

Bovine tuberculosis (TB) is a disease of zoonotic importance for which control and eradication programmes have been carried out in many countries for decades. While the impact of these programmes on public health is still uncertain, the impact on trade is significant because of movement restrictions for animals, costs of testing and culling. The objective of this systematic review was to provide a contribution to the general debate over costs against benefits for the control and eradication of bovine TB in cattle. The search strategy was performed on four electronic databases following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The selection process, data abstraction and quality appraisal were carried out according to the Cochrane Collaboration guidelines. The search identified 66 articles out of which eight fulfilled the inclusion criteria. The evidence gathered in this review by combining the conclusions of the most methodologically sound articles supports the idea that, when multiple cost and benefit components are taken into account, efforts to control or eradicate bovine TB may be effective in reducing disease prevalence, economically viable and worth doing.
