Epidemiological Measures in the Context of the COVID-19 Pandemic.
2020
BACKGROUND: The various epidemiological indicators used to communicate the impact of COVID-19 have different strengths and limitations. METHODS: We conducted a selective literature review to identify the indicators used and to derive appropriate definitions. We calculated crude and age-adjusted indicators for selected countries. RESULTS: The proportion of deaths (case fatality proportion [CFP]; number of deaths/total number of cases) is commonly used to estimate the severity of a disease. If the CFP is used for purposes of comparison, the existence of heterogeneity in the detection and registration of cases and deaths has to be taken into account. In the early phase of an epidemic, when cas…
P145 Inflammatory Bowel Disease patients requiring surgery can be treated in referral centres regardless of the COVID-19 status of the hospital: resu…
2021
Abstract Background Little is known regarding the outcomes of inflammatory bowel disease (IBD) patients who required surgery during the outbreak of Coronavirus disease 19 (COVID-19). This study aimed to compare outcomes of IBD patients undergoing surgery in COVID-19-treatment and COVID-19-free hospitals. Methods Retrospective study involving patients undergoing IBD surgery in seven centres (six COVID-19-treatment hubs and one COVID-free hospital) across 5 European countries during the period of highest reduction of elective activity due to the first peak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. Predictive variables of the risk of moderate-to-severe postope…
Can Information about Pandemics Increase Negative Attitudes toward Foreign Groups? A Case of COVID-19 Outbreak
2020
Pathogen threat can translate into a willingness to distance oneself from others on a psychological level. Building on this notion, we predicted that the ongoing coronavirus pandemic can affect attitudes toward foreign nationalities. We explored the intergroup consequences of the current epidemiological situation in two studies involving a total of 652 participants. In correlational Study 1, we showed a positive relationship between media exposure in the United Kingdom (UK) and in Poland, and prejudice to four foreign nationalities. Study 2 showed that negative affect toward Italians (i.e., a nation struggling with the most severe COVID-19 outbreak at the time of the study) was indirectly p…
Onychomadesis Outbreak in Valencia, Spain Associated with Hand, Foot, and Mouth Disease Caused by Enteroviruses
2011
This report evaluates the June 2008 onychomadesis outbreak in Valencia, Spain. The study sample consisted of 221 onychomadesis cases and 77 nonaffected individuals who lived close to those affected. We collected data on dietary variables, hygiene products, and individual pathological histories. Feces and blood specimens were collected from 44 cases and 24 controls to evaluate exposure to infectious agents. Pathological background data revealed a high frequency (61%) of hand, foot, and mouth disease among the onychomadesis cases. Coxsackievirus A10 was the most commonly detected enterovirus in both case and control groups (49%). Other enteroviruses such as coxsackieviruses A5, A6, A16, B1, a…
Projecting the spread of COVID-19 for Germany
2020
We model the evolution of the number of individuals that are reported to be sick with COVID-19 in Germany. Our theoretical framework builds on a continuous time Markov chain with four states: healthy without infection, sick, healthy after recovery or after infection but without symptoms and dead. Our quantitative solution matches the number of sick individuals up to the most recent observation and ends with a share of sick individuals following from infection rates and sickness probabilities. We employ this framework to study inter alia the expected peak of the number of sick individuals in a scenario without public regulation of social contacts. We also study the effects of public regulati…
SARS-CoV-2 outbreak in medical employees in a large urologic department: Spread, containment and outcome.
2021
Background The SARS-CoV-2 pandemic presents an unprecedented challenge to health care systems worldwide. Data on SARS-CoV-2 transmission in a hospital is rare and outbreaks among health care professionals are complex to control. Material and Methods Over the course of 6 consecutive weeks we recorded data on an exponential outbreak of SARS-CoV-2 within our department. We reconstructed the assumed route of the spread of infection, and the employees’ acute and late symptoms. Increasing preventive measures (mandatory face masks, intense training in hygiene, physical distancing whenever possible, and termination of visits from outside the hospital) were implemented. Results Within 6 weeks, 13 em…

Sequential evolution of genotype GII.4 norovirus variants causing gastroenteritis outbreaks from 2001 to 2006 in Eastern Spain.
2008
Noroviruses are the most common cause of outbreaks of viral gastroenteritis worldwide. Norovirus outbreaks were surveyed in Catalonia and the region of Valencia (Eastern Spain) between January 2001 and December 2006 as part of the European Union funded network "Food-borne viruses in Europe". During this time the etiology and epidemiological features of 194 outbreaks of acute non-bacterial gastroenteritis were investigated and norovirus was identified as causing 169 (87.1%) of them. Molecular epidemiology of viral strains was studied by RT-PCR and sequencing part of the RNA polymerase gene in ORF1 from 153 outbreak strains. The most commonly identified norovirus genotype was GII.4 (71.9% of …
The risk of suicide in healthcare workers in nursing home: An exploratory analysis during COVID-19 epidemic.
2021
In March 2020, the World Health Organization declared the coronavirus disease 19 (COVID‐19) outbreak as global pandemic. Nursing homes were particularly struck by the COVID‐19 outbreak, with some authors considering the COVID‐19 pandemic as the “ground zero” for these structures.
Patient-to-patient transmission of hepatitis C virus (HCV) during colonoscopy diagnosis
2010
Abstract Background No recognized risk factors can be identified in 10-40% of hepatitis C virus (HCV)-infected patients suggesting that the modes of transmission involved could be underestimated or unidentified. Invasive diagnostic procedures, such as endoscopy, have been considered as a potential HCV transmission route; although the actual extent of transmission in endoscopy procedures remains controversial. Most reported HCV outbreaks related to nosocomial acquisition have been attributed to unsafe injection practices and use of multi-dose vials. Only a few cases of likely patient-to-patient HCV transmission via a contaminated colonoscope have been reported to date. Nosocomial HCV infecti…
