MICROORGANISMS 20/10/21 Epidemiology of Legionnaires’ Disease in Italy, 2004–2019: A Summary of Available Evidence. Legionnaires’ disease (LD) incidence has been increasing in several European countries since 2011.

MICROORGANISMS 20/10/21 Epidemiology of Legionnaires’ Disease in Italy, 2004–2019: A Summary of Available Evidence

Currently, Italy is experiencing high notification rates for LD, whose cause still remains scarcely understood. We sought to summarize the available evidence on the epidemiology of LD in Italy (2004–2019), characterizing the risk of LD by region, sex, age group, and settings of the case (i.e., community, healthcare, or travel-associated cases). Environmental factors (e.g., average air temperatures and relative humidity) were also included in a Poisson regression model in order to assess their potential role on the annual incidence of new LD cases.

National surveillance data included a total of 23554 LD cases occurring between 2004 and 2019 (70.4% of them were of male gender, 94.1% were aged 40 years and older), with age-adjusted incidence rates increasing from 1.053 cases per 100,000 in 2004 to 4.559 per 100,000 in 2019. EUROSURVEILLANCE 24/06/21 Provincial trends in Legionnaires’ disease are not explained by population structure in Denmark, 2015 to 2018. PATHOGENS 03/05/21 Occurrence of Legionella spp. in Man-Made Water Sources: Isolates Distribution and Phylogenetic Characterization in the Emilia-Romagna Region. Legionella species distribution in the Emilia-Romagna region, involving hospital (H) and community (C) environments, was conducted.

PATHOGENS 03/05/21 Occurrence of Legionella spp. in Man-Made Water Sources: Isolates Distribution and Phylogenetic Characterization in the Emilia-Romagna Region

Legionella culture, agglutination test, and mip-gene sequencing were applied on 240 isolates. The analysis showed a higher prevalence of non-Legionellapneumophila (n-Lp) species (84.1%) compared with L. pneumophila (Lp) (15.9%), with a higher frequency of n-Lp with respect to Lp species in both environments (77.6% and 96.4%, in H and C, respectively). The Shannon index showed a significant difference in Legionella distribution (p = 0.00017), with a significant abundance of Lp in the H compared with C environment (p = 0.00028). The continuous disinfection treatment in H could contribute to adaptive survival of the Lp species. Phylogenetic analysis revealed a conservative clade distribution between H and C: L. feeleii clade with three subclades in C and the Lp clade with five subclades in H and two in C, respectively. ►▼ Show Figures Figure 1 ►▼ Show Figures.

Assessment of antibiotic susceptibility of Legionella pneumophila isolated from water systems in Poland Introduction and objective:Several studies have reported therapy failures in patients with legionnaires’disease; however, antimicrobial resistance of clinical and environmental isolates of Legionella spp. has not yet been documented.

Ann Agric Environ Med 2017;24(1):66–69 Assessment of antibiotic susceptibility of Legionella pneumophila isolated from water systems in Poland

Routine susceptibility testing of Legionella spp. is not recommended because of difficulties in determining standard minimal inhibitory concentration values. The purpose of this study was to analyze the antimicrobial susceptibility of Legionella pneumophila. strains isolated from a water supply system. Material and Methods:Twenty-eight isolates of L. pneumophila (16 – L. pneumophila SG 1, 12 – L. pneumophila SG 2–14) obtained from water systems in public buildings in Poland were tested.

Susceptibility testing was performed using the E-test method. Results:Among the tested strains, L. pneumophila was the only one resistant to azithromycin.

Confirming Legionnaires’ Disease Outbreak by Genome-Based Method, Germany, 2012 - Volume 22, Number 7—July 2016

On July 31, 2012, the State Health Agency of Rhineland-Palatinate was informed by the local health department of the city of Zweibrücken that 10 patients tested positive for Legionella pneumophila, the bacterium that causes Legionnaires’ disease. The onset of disease for all case-patients was from June 26 through July 25, which exceeded the yearly average of 1–4 patients a month. By August 23, we had received notifications of 19 patients with pneumonia and notification of 1 patient who did not exhibit pneumonia.

We set 3 parameters for reporting a patient as a Legionnaires’ disease case-patient. THE GUARDIAN 14/11/12 London at risk of 'catastrophic' legionnaires' outbreak, report says. Legionella bacteria, which cause legionnaires' disease.

THE GUARDIAN 14/11/12 London at risk of 'catastrophic' legionnaires' outbreak, report says

The HSE report found that compliance with health and safety requirements was inadequate at almost three-quarters of the sites inspected. Photograph: Alamy London could experience an outbreak of legionnaires' disease with potentially "catastrophic consequences" for people's health because of poor management of cooling towers and evaporative condensers near busy transport hubs and Olympic venues, according to a leaked Health and Safety Executive (HSE) report. The stark warning is contained in a report by the HSE detailing the results of inspections for the presence of the legionella bacteria, which causes the disease, at 62 sites around the capital, carried out by its inspectors as part of the safety preparations for this summer's Olympic Games. It reveals that compliance with health and safety requirements was inadequate at almost three-quarters of the sites. The HSE initially identified 106 sites for inspection.

Une usine d’engrais chimique serait à l’originie de la contamination. “C’est une des épidémies de légionellose les plus importantes de l’Histoire”, titrait jeudi l’hebdomadaire Expresso. Il est vrai que le bilan provisoire donne le tournis : 7 morts, 48 cas graves en observation, 311 personnes infectées par la bactérie. La vague de contamination ne semble pas encore enrayée. Si la maladie est circonscrite aux environs de la ville portugaise de Vila Franca de Xira, dans la banlieue de Lisbonne, les individus contaminés ont été hospitalisés là où ils se trouvaient lorsque les symptômes sont apparus, c’est-à-dire dans le reste du pays, en Angola et même au Pérou.

PARLEMENT EUROPEEN - Réponse à question E-005071/2012 Réglementation européenne sur les brumisateurs et prévention des risques s

On a constaté ces dernières années la multiplication de ces systèmes dans les établissements publics ainsi que dans la sphère privée. Les brumisateurs ont différents usages correspondant à différentes attentes: rafraîchissement, humidification, décor, abattage de poussières et traitement d'odeurs. Ces systèmes sont amenés à se démocratiser davantage avec les fortes variations climatiques, le changement des comportements des consommateurs et les rénovations urbaines. Cependant, il n'existe aujourd'hui pas de réglementation au niveau européen régissant le contrôle et les normes sanitaires de ces appareils. Ainsi, s'il est possible d'éviter les crises sanitaires majeures, notamment grâce aux spécificités du droit des États membres, rien n'assure la prévention des problèmes ponctuels graves pour le consommateur attablé à une terrasse de café, un promeneur à proximité de ces installations ou un riverain.
