The Russian invasion of Ukraine on February 24, 2022, has had devastating effects on the Ukrainian population and the global economy, environment, and political order. However, little is known about the psychological states surrounding the outbreak of war, particularly the mental well-being of individuals outside Ukraine. Here, we present a longitudinal experience-sampling study of a convenience sample from 17 European countries (total participants = 1,341, total assessments = 44,894, countries with >100 participants = 5) that allows us to track well-being levels across countries during the weeks surrounding the outbreak of war. Our data show a significant decline in well-being on the day of the Russian invasion. Recovery over the following weeks was associated with an individual's personality but was not statistically significantly associated with their age, gender, subjective social status, and political orientation. In general, well-being was lower on days when the war was more salient on social media. Our results demonstrate the need to consider the psychological implications of the Russo-Ukrainian war next to its humanitarian, economic, and ecological consequences., (© 2024. The Author(s).)

Background: In 2011, 15 deep-seated Propionibacterium acnes infections were identified in patients following craniotomies in a hospital in the UK., Aim: To describe the outbreak and report findings from the investigation undertaken in order to identify the source and risk factors and inform control measures., Methods: Data were obtained from hospital clinical records and included patient and surgical variables. Cases were defined as patients with microbiologically confirmed deep or organ space surgical site infection (SSI) caused by P. acnes following craniotomy undertaken in 2011. Four controls per case were randomly selected from patients who had a craniotomy in 2011 but who did not develop any SSI. The relationship between infection and putative exposures was examined using multivariate regression techniques. Infection prevention procedures and the theatre environment were reviewed to assess compliance with existing standards., Findings: Fifteen cases and 65 controls were recruited. Odds of infection were higher for those who had a dural implant inserted during their operation [adjusted odds ratio (aOR): 14.6; 95% confidence interval (CI): 0.95-∞] and for those who had alcohol/Betadine ® /chlorhexidine mix as a disinfectant (aOR: 7.9; 95% CI: 0.8-∞). Environmental investigations suggested that theatre ventilation systems delivered air exchange rates below the recommended standard., Conclusion: There was a positive association between using dural implants and P. acnes infection. Infection may have been facilitated by inefficient use of skin disinfectant and environmental factors. Recommendations included ongoing surveillance, the use of chlorhexidine skin disinfectant, ensuring adequate air exchanges and appropriate use of doors in theatre to minimize air turbulence., (Copyright © 2017 The Healthcare Infection Society.

Background: Meningococcal infection is fatal in 10% of cases, and age-specific attack rates are highest in infancy. A nursery outbreak was declared just before a bank holiday weekend in August 2010, when two children attending the same nursery were confirmed to have meningococcal infection. Although such outbreaks are rare, they generate considerable public alarm and are challenging to manage and control. This report describes the investigation and public health response to the outbreak., Results: Both cases had relatively mild disease and were confirmed as having serogroup B infection. Chemoprophylaxis and advice were given to most of the 146 children and 30 staff at the nursery. Within 28 hours of declaring the outbreak, over 95% of parents received information, advice and prescriptions for their children. GPs were also given information and the after-hours service provided continuity over the weekend. No further cases were identified and the outbreak was closed four weeks after being declared., Conclusions: Considerable logistical challenges were involved in providing timely advice and chemoprophylaxis to the entire nursery and staff one day before a bank holiday weekend. The speed of the public health response and implementation of preventive measures was crucial in providing assurance to parents and staff, and reducing their anxiety. The decision to provide on-site prescribing at the nursery (coupled with information sessions and individual counselling) proved to be a key implementation-success factor. Effective coordination and management by the outbreak control team was able to rapidly provide leadership, delegate tasks, identify gaps, allocate resources and ensure a proactive media response. A number of useful lessons were learnt and recommendations were made for future local practice.

Twenty-one confirmed cases of Legionnaires’ disease (Legionella pneumophila serogroup 1) were identified in the Stoke-on-Trent area of England with onsets since 2 July 2012. Sequence-based typing results are available for nine cases; all are a unique type (ST1268). Initial interviews highlighted a number of possible environmental sources. Inspection of premises of interest revealed an operating spa pool on display, from which the outbreak strain was identified. All cases had visited the retail premise with this spa pool.

In October 2007 an increase in laboratory-confirmed cryptosporidiosis cases in Staffordshire, England prompted an outbreak investigation. Case ascertainment included interviewing suspected cases and contacts and obtaining faecal specimens from those with diarrhoea for laboratory identification. Over a three-month period we identified 57 cases of cryptosporidiosis (39 confirmed) distributed across 36 households. The majority of cases (69%) were younger than 20 years. The most plausible exposure was multiple swimming episodes (56% of cases) in 13 local public swimming pools. One large swimming pool was most frequently visited by swimmers and considered a significant contributor to transmission because of substandard filtration and maintenance systems. Control measures focused on inspecting and improving operating standards at swimming pools, hygiene information to swimmers, and early detection and exclusion of cases. The rapid case investigation described in this paper provided adequate information for the early detection and control of a typical seasonal swimming pool related cryptosporidiosis outbreak. Ensuring adequate filtration standards at public swimming pools particularly before the high use periods of late summer and autumn remains a priority.

Over the last 6 years there has been a decline in the incidence of measles in Cape Town. However, during August 1992 an outbreak occurred, with cases reported at many schools in children presumably immunised. The objectives of this study were to characterise the epidemic in Cape Town and to determine possible reasons for the outbreak. The investigation consisted of two components--a description of the epidemic and an investigation of an outbreak at one primary school. Results indicate that during the last 4 months of the year, 757 cases were notified in Cape Town, compared with 144 in the first 8 months. The epidemic affected mainly white and coloured children over 5 years of age (P < 0.001). In contrast, during the period before the epidemic most cases occurred in black children and in those aged less than 1 year (P < 0.001). There was no significant increase in hospitalised cases. Investigation of the outbreak at one school revealed that the attack rate was 7.6% (25/329 children). Immunisation coverage (at least one dose of any measles vaccine) was 91% and vaccine efficacy was estimated to be 79% (95% CI 55-90); it was highest for monovalent measles (100%) and lowest for measles-mumps-rubella (74%). The epidemiology of measles in Cape Town has thus changed as evinced in this epidemic, with an increase in the number of cases occurring in older, previously vaccinated children. The possible reasons for this include both primary and secondary vaccine failure.(ABSTRACT TRUNCATED AT 250 WORDS)
