Impact of the 2021 Flood Disasters on human social and mental health, focusing on elderly people in Germany

Flooding is one of the most common environmental disasters that cause mental and physical health problems. Flooding can cause loss of life and damage to personal property and critical public health infrastructure. Elderly people are at particular risk of the effects of floods, and their implications on social and mental health. This study is being conducted in the Ahr Valley, Germany which was heavily flooded in July 2021 (Figure 1). This flood destroyed towns and villages in thevalley, causing more than 180 casualties and huge material damage (Silvia et al., 2021). The sudden-onset flood disaster caught the Ahr basin residents by surprise and had an impact on the mental and social health of the affected people. This study addresses the mental and social health effects of the 2021 flooding in the Ahr Valley, Germany, on elderly people. Preliminary findings, the research approach to data collection, survey, challenges faced, and their implications on the progress of the project will be introduced

Developing a strategy for assessing the impact of the 2021 flood disaster on the elderly in the Ahr valley, Germany

The sudden-onset flood disaster in the summer of 2021 caught the Ahr basin residents by surprise and had an impact on the mental and social health and well-being of the affected people. This study will address how the 2021 flooding in the Ahr Valley, Germany, may have affected the mental and social health of elderly people. The study design, research approach, and methods of data collection will be introduced. Spatial data and analysis of the flood-affected area were used to improve our understanding of the flood-affected area and will help guide future analyses

Preparing schools for future pandemics: Insights on Water, Sanitation and Hygiene solutions from the Brazilian School Reopening Policies.

Post-COVID-19, schools urgently need to enhance infection control and prevention (IPC) measures, including water, sanitation, and hygiene (WASH), to prepare for future outbreaks and pandemics. Particularly in Brazil, that is of particular concern, as students are still recovering from the 20th longest school closure in the world. Hence, the current study had two goals: (i) to describe WASH solutions outlined in policies released at the federal, state, and capital city levels in Brazil during the COVID-19 pandemic for the safe reopening of schools and (ii) to discuss their potential to enhance school's capacity to remain operational during a new pandemic or outbreak. With a qualitative exploratory approach, we performed content analysis to discuss the direction (what, where, how and for whom?) of 66 public policies by integrating four frameworks. Solutions were discussed in the light of the principles of human rights and the human rights to water and sanitation, international guidelines for WASH and IPC in schools and the Sphere minimum standards for humanitarian aid. One hundred and fifty-nine solutions, spanning five thematic areas and five population groups, including software and hardware interventions, were compiled for potential use in Brazil and beyond. While suggested solutions have the potential to provide a cleaner and safer learning environment, it is essential to exercise caution when implementing these measures and adapt them to the specific circumstances of each school

Analysing the outbreaks of leptospirosis after floods in Kerala, India

A growing number of studies have linked the incidence of leptospirosis with the occurrence of flood events. Nevertheless, the interaction between flood and leptospirosis has not been extensively studied to understand the influence of flood attributes in inducing new cases. This study reviews leptospirosis cases in relation to multiple flood occurrences in Kerala, India. Leptospirosis data were obtained for three years: 2017 (non-flood year) and two years with flooding—2018 (heavy flooding) and 2019 (moderate flooding). We considered the severity of flood events using the discharge, duration and extent of each flooding event and compared them with the leptospirosis cases. The distribution of cases regarding flood discharge and duration was assessed through descriptive and spatiotemporal analyses, respectively. Furthermore, cluster analyses and spatial regression were completed to ascertain the relationship between flood extent and the postflood cases. This study found that postflood cases of leptospirosis can be associated with flood events in space and time. The total cases in both 2018 and 2019 increased in the post-flood phase, with the increase in 2018 being more evident. Unlike the 2019 flood, the flood of 2018 is a significant spatial indicator for postflood cases. Our study shows that flooding leads to an increase in leptospirosis cases, and there is stronger evidence for increased leptospirosis cases after a heavy flood event than after a moderate flooding event. Flood duration may be the most important factor in determining the increase in leptospirosis infections.</p

Knowledge, protective behaviours, and perception of Lyme disease in an area of emerging risk: results from a cross-sectional survey of adults in Ottawa, Ontario

BackgroundThe number of Lyme disease risk areas in Canada is growing. In regions with emerging tick populations, it is important to emphasize peridomestic risk and the importance of protective behaviours in local public health communication. This study aims to identify characteristics associated with high levels of Lyme disease knowledge and adoption of protective behaviours among residents in the Ottawa, Ontario region.MethodsA geographically stratified web survey was conducted in November 2020 (n = 2018) to determine knowledge, attitudes, and practices regarding Lyme disease among adult residents. Responses were used to calculate: (i) composite scores for knowledge and adoption of protective practices; and (ii) an exposure risk index based on reported activity in woodlands during the spring-to-fall tick exposure risk period.Results60% of respondents had a high knowledge of Lyme disease, yet only 14% indicated they often use five or more measures to protect themselves. Factors strongly associated with a high level of Lyme disease knowledge included being 55 or older (Odds Ratio (OR) = 2.04), living on a property with a yard (OR = 3.22), having a high exposure index (OR = 1.59), and knowing someone previously infected with Lyme disease (OR = 2.05). Strong associations with the adoption of a high number of protective behaviours were observed with membership in a non-Indigenous racialized group (OR = 1.70), living on a property with a yard (OR = 2.37), previous infection with Lyme disease (OR = 2.13), prior tick bite exposure (OR = 1.62), and primarily occupational activity in wooded areas (OR = 2.31).ConclusionsThis study highlights the dynamics between Lyme disease knowledge, patterns of exposure risk awareness, and vigilance of personal protection in a Canadian region with emerging Lyme disease risk. Notably, this study identified gaps between perceived local risk and protective behaviours, presenting opportunities for targeted enhanced communication efforts in areas of Lyme disease emergence

Adverse childhood experiences increase HIV risk factors in Agbogbloshie, Ghana

Adverse Childhood Experiences (ACEs) have been associated with increased risk factors for HIV transmission, but the causal pathway is uncertain. This study documents the prevalence of ACEs by gender and their association with HIV risk factors and assesses depressive symptoms as mediating this relationship. A cross-sectional survey was conducted in 2019 among a representative sample of men and women, aged 18–24 years, living in an informal settlement in Accra, Ghana. Data on sociodemographic characteristics, ACEs, ten HIV risk factors (five sexual behaviors, HIV/AIDS knowledge, sexual assault, three substance use behaviors), and depressive symptoms were collected. Multiple logistic regression models were estimated to assess the independent association between four or more ACEs and each of the ten HIV risk factors. Structural equation models examined depressive symptoms as a mediator in these associations. A third (34.6%) of participants reported four or more ACEs, and among those who experienced four or more ACEs 60% were men and 40% were women. Gender did not modify the effect of the association between four or more ACEs and HIV factors and therefore the multiple regression analysis was not stratified by gender. After controlling for sociodemographic covariates and depressive symptoms, having experienced four or more ACEs was associated with alcohol use (OR = 3.88; 95% CI: 1.34, 11.21), injection drug use (OR = 2.78; 95% CI: 1.15, 6.73), low knowledge of HIV (OR = 3.59; 95% CI: 1.43, 9.00), sexually transmitted infection (OR = 3.70; 95% CI: 1.15, 11.96), and sexual assault (OR = 3.58; 95% CI: 1.07, 12.05). There was some evidence that depressive symptoms could be mediating the association between reporting four or more ACEs and ever having a sexually transmitted infection. The mitigation of ACEs and depressive symptoms has the potential to decrease HIV risk factors and thus reduce the risk for HIV transmission among youth living in informal settlements

Ixodes scapularis density and Borrelia burgdorferi prevalence along a residential-woodland gradient in a region of emerging Lyme disease risk.

The environmental risk of Lyme disease, defined by the density of Ixodes scapularis ticks and their prevalence of Borrelia burgdorferi infection, is increasing across the Ottawa, Ontario region, making this a unique location to explore the factors associated with environmental risk along a residential-woodland gradient. In this study, we collected I. scapularis ticks and trapped Peromyscus spp. mice, tested both for tick-borne pathogens, and monitored the intensity of foraging activity by deer in residential, woodland, and residential-woodland interface zones of four neighbourhoods. We constructed mixed-effect models to test for site-specific characteristics associated with densities of questing nymphal and adult ticks and the infection prevalence of nymphal and adult ticks. Compared to residential zones, we found a strong increasing gradient in tick density from interface to woodland zones, with 4 and 15 times as many nymphal ticks, respectively. Infection prevalence of nymphs and adults together was 15 to 24 times greater in non-residential zone habitats. Ecological site characteristics, including soil moisture, leaf litter depth, and understory density, were associated with variations in nymphal density and their infection prevalence. Our results suggest that high environmental risk bordering residential areas poses a concern for human-tick encounters, highlighting the need for targeted disease prevention
