Enfoque Rápido en Contexto Comunitario (ERCC): evaluando las medidas preventivas para Hantavirus en la Comarca Andina Patagónica desde la perspectiva de la participación comunitaria / Rapid Approach in Community Context (ERCC): evaluating preventive measures for Hantavirus in the Andean Patagonian Region from the perspective of community participation

Introducción: la creciente preocupación por eventos epidémicos de origen zoonótico generó la necesidad de estrategias integrales que corrigiesen la baja adaptabilidad y tensiones que se generan al implementar acciones de orden jerárquico superior en el contexto comunitario. Con el objeto de explicar un Enfoque Rápido en Contexto Comunitario (ERCC), este trabajo se propone evaluar dentro del contexto de un programa de salud pública la participación comunitaria en la prevención del Hantavirus en la Comarca Andina del Paralelo 42. Metodología: El presente ERCC utilizó visitas y observaciones al sitio, entrevistas cara a cara y grupales, precedidas por una revisión documental de la literatura. La información se recopiló en un corto período de tiempo y el análisis se utilizó para desarrollar recomendaciones informadas para los tomadores de decisiones de salud pública. Resultados: Se observo que cada comunidad enfrenta desafíos más allá del hantavirus y es esencial que epidemiólogos, prestadores de servicios asistenciales y municipalidades trabajen más estrechamente con la población local para prevenir y manejar mejor cualquier brote de enfermedad. Se pudieron identificar 6 recomendaciones que le permitirían a las comunidades un mejor manejo de futuros brotes con un enfoque participativo. Conclusiones: El ERCC es una intervención rápida y discreta que puede ser llevada a cabo por un pequeño equipo con una interferencia mínima en la comunidad. El ERCC también podría ser adaptado por las autoridades de salud pública a muchos contextos diferentes, incluso con grupos vulnerables, para ayudar a que la promoción y la prevención sean más relevantes y efectivas a nivel local (AU)

Introduction: the growing concern for epidemic events of zoonotic origin generated the need for comprehensive strategies that correct the low adaptability and tensions generated when implementing actions of higher hierarchical order in the community context. In order to explain a Rapid Approach in Community Context (ERCC), this paper aims to evaluate within the context of a public health program community participation in the prevention of Hantavirus in the Andean Region of the 42nd Parallel. Methodology: The present ERCC used site visits and observations, face-to-face and group interviews, preceded by a documentary review of the literature. The information was collected over a short period of time and the analysis was used to develop informed recommendations for public health decision makers. Results: It was observed that each community faces challenges beyond hantavirus and it is essential that epidemiologists, care providers and municipalities work more closely with the local population to better prevent and manage any disease outbreak. We were able to identify 6 recommendations that would allow communities to better manage future outbreaks with a participatory approach. Conclusions: The ERCC is a rapid and discreet intervention that can be carried out by a small team with minimal interference in the community. The ERCC could also be adapted by public health authorities to many different contexts, including with vulnerable groups, to help make promotion and prevention more relevant and effective at the local level (AU)

Telemedicine for the Clinical Management of Diabetes; Implications and Considerations After COVID-19 Experience.

Telemedicine is a clinical approach that was seldom used in the day-to-day practice, if not only in certain settings, before the COVID-19 pandemic. As stated by the WHO, telemedicine is: the delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies (ICT) for the exchange of valid information for diagnosis, treatment and prevention of disease and injuries, …. Telemedicine has actually represented the most useful and employed tool to maintain contacts between patients and physicians during the period of physical distance imposed by the pandemic, especially during the lockdown. Diabetes in particular, a chronic disease that often needs frequent confronting between patient and health professionals has taken advantage of the telehealth approach. Nowadays, technological tools are more and more widely used for the management of diabetes. In this review results obtained by telemendicine application in type 1 and type 2 diabetic individuals during COVID-19 are revised, and future perspectives for telemedicine use to manage diabetes are discussed.

Professional practice for COVID-19 risk reduction among health care workers: A cross-sectional study with matched case-control comparison.

BACKGROUND: Health care workers (HCWs) are particularly exposed to COVID-19 and therefore it is important to study preventive measures in this population. AIM: To investigate socio-demographic factors and professional practice associated with the risk of COVID-19 among HCWs in health establishments in Normandy, France. METHODS: A cross-sectional and 3 case-control studies using bootstrap methods were conducted in order to explore the possible risk factors that lead to SARS-CoV2 transmission within HCWs. Case-control studies focused on risk factors associated with (a) care of COVID-19 patients, (b) care of non COVID-19 patients and (c) contacts between colleagues. PARTICIPANTS: 2,058 respondents, respectively 1,363 (66.2%) and 695 (33.8%) in medical and medico-social establishments, including HCW with and without contact with patients. RESULTS: 301 participants (14.6%) reported having been infected by SARS-CoV2. When caring for COVID-19 patients, HCWs who declared wearing respirators, either for all patient care (ORa 0.39; 95% CI: 0.29-0.51) or only when exposed to aerosol-generating procedures (ORa 0.56; 95% CI: 0.43-0.70), had a lower risk of infection compared with HCWs who declared wearing mainly surgical masks. During care of non COVID-19 patients, wearing mainly a respirator was associated with a higher risk of infection (ORa 1.84; 95% CI: 1.06-3.37). An increased risk was also found for HCWs who changed uniform in workplace changing rooms (ORa 1.93; 95% CI: 1.63-2.29). CONCLUSION: Correct use of PPE adapted to the situation and risk level is essential in protecting HCWs against infection.

Local characterization of the COVID-19 response: the case of a lockdown in Lusaka, Zambia.

BACKGROUND: The onset of the COVID-19 pandemic has sparked heated debate among scholars on the relevance of lockdowns. There are those in favor of the lockdown and others who are critical of it. However, despite the increased interest in understanding the relevance of lockdowns, there still has not been much focus on its relevance in countries like Zambia. Thus, with the help of the Social Representation Theory (SRT), we set out to explore and document the local characterization of the lockdown by residents of Lusaka, Zambia. METHODS: We recruited our participants through convenient and purposive sampling techniques. This was done through the use of the ZAMTEL public phone records. Initial contact was made to potential participants, and they were asked of their availability and willingness to participate in the interview. Upon agreeing to participate, they were included in the sample. A total of 68 people were selected to take part in this study. Their age ranged from 20 to 76 years old. 33 of them were male and 35 females. After this, we conducted interviews with the 68 participants. Due to COVID-19 restrictions, our interviews were conducted via telephone in conformity with the recommendations from the IRB in Lusaka and the advice of the ministry of health. We anonymized the demographic characteristics and responses from our participants. Later, thematic analysis was used to analyze the data. RESULTS: The lockdown was on one hand lauded for slowing down the incidence rates, preventing fatalities, and protecting the healthcare system from collapse. On the other hand, it was criticized for exacerbating poverty levels, unemployment rates, increasing the rate of mental health problems, aiding gender-based violence, and intensifying political repression and corruption. The results speak to the complexity in the characterization of the lockdown as a response to COVID-19 in Lusaka, Zambia. This observation demonstrates the folly of viewing, applying and characterizing the COVID-19 lockdown as a 'one-size-fits-all' approach in Lusaka, Zambia. CONCLUSION: Rather than establishing the lockdown as an incontestable good, as it is depicted by some scholars or as useless by its critics, our findings instead demonstrate the diversity and complexity in how it is locally viewed by Lusaka residents. The study provides grounds for caution on simplistic and binary characterization of lockdowns. It indicates the need for careful dialog between the designers of lockdowns and citizens in order to tailor such interventions to local realities in context-specific ways. It also shows that though the development of such interventions, all the various and complex elements it embodies must be taken into account in order to realize optimum outcomes.

Factors related with the incidence of acute respiratory infections in toddlers in Sleman, Yogyakarta, Indonesia: Evidence from the Sleman Health and Demographic Surveillance System.

Various factors associated with Acute Respiratory Infections (ARI) in toddlers have been widely observed, but there are no studies using data from the Sleman Health and Demographic Surveillance System (HDSS). This study aimed to determine the factors associated with ARI in children under five in Sleman, Yogyakarta, Indonesia. This research was an observational analytic study with a cross-sectional design, using secondary data from the Sleman HDSS. Data of 463 children under five who met the inclusion and exclusion criteria were used in this study. Inclusion criteria were toddlers who have complete observed variable data. The variables observed were the characteristics of children under five, the attributes of the mother, the physical condition of the house, the use of mosquito coils, sanitation facilities, and sources of drinking water. The exclusion criteria were toddlers with pulmonary tuberculosis in the past year. Data analysis used chi-squared tests for bivariate analysis and multivariate logistic regression analysis. The results showed that working mothers had a greater risk of ARI under five children with OR 1.46 (95% CI = 1.01-2.11), and groundwater as a water source was a protective factor against the occurrence of ARI in toddlers with OR 0.46 (95% CI = 0.26-0.81). After a logistic regression analysis was performed, only the drinking water source variable had a statistically significant relationship with the incidence of ARI in children under five with OR = 0.47 (95% CI = 0.268-0.827). Research on the relationship between water quality and the incidence of ARI in children under five is needed to follow up on these findings.

Skin problems related to personal protective equipment among healthcare workers during the COVID-19 pandemic (online research).

INTRODUCTION: Coronavirus disease-2019 (COVID-19) is a highly contagious infectious disease that first appeared in Wuhan, China, in December 2019. Health care workers (HCWs) are at increased risk of infection because the virus is highly contagious and can be transmitted by a variety of routes. Health care workers are required to use a variety of personal protective equipment (PPE) for prolonged hours and, as a result, they face varying degrees of cutaneous complications. METHODS: We conducted a cross-sectional online questionnaire survey to investigate skin problems caused by the use of PPE and personal hygiene measures. We developed a survey with 32 questions using Google forms and distributed it via WhatsApp and Facebook groups. RESULTS: A total of 1142 responses were obtained. Among the respondents, 88.1% reported adverse skin reactions due to PPE and personal hygiene measures. Female sex, working as a nurse, wearing PPE more than 6 h/day, and working more than 3 days/week increase the risk of PPE-related skin problems. CONCLUSION: In this study, we highlighted skin problems related to PPE and found out risk factors for PPE-related skin problems.

Behavioural insights and attitudes on community masking during the initial spread of COVID-19 in Hong Kong.

INTRODUCTION: Community face mask use during the coronavirus disease 2019 (COVID-19) pandemic has considerably differed worldwide. Generally, Asians are more inclined to wear face masks during disease outbreaks. Hong Kong has emerged relatively unscathed during the initial outbreak of COVID-19, despite its dense population. Previous infectious disease outbreaks influenced the local masking behaviour and response to public health measures. Thus, local behavioural insights are important for the successful implementation of infection control measures. This study explored the behaviour and attitudes of wearing face masks in the community during the initial spread of COVID-19 in Hong Kong. METHODS: We observed the masking behaviour of 10 211 pedestrians in several regions across Hong Kong from 1 to 29 February 2020. We supplemented the data with an online survey of 3199 respondents' views on face mask use. RESULTS: Among pedestrians, the masking rate was 94.8%; 83.7% wore disposable surgical masks. However, 13.0% wore surgical masks incorrectly with 42.5% worn too low, exposing the nostrils or mouth; 35.5% worn 'inside-out' or 'upside-down'. Most online respondents believed in the efficacy of wearing face mask for protection (94.6%) and prevention of community spread (96.6%). Surprisingly, 78.9% reused their mask; more respondents obtained information from social media (65.9%) than from government websites (23.2%). CONCLUSIONS: In Hong Kong, members of the population are motivated to wear masks and believe in the effectiveness of face masks against disease spread. However, a high mask reuse rate and errors in masking techniques were observed. Information on government websites should be enhanced and their accessibility should be improved.

Ugandan stakeholder hopes and concerns about gene drive mosquitoes for malaria control: new directions for gene drive risk governance.

BACKGROUND: The African Union's High-Level Panel on Emerging Technologies identified gene drive mosquitoes as a priority technology for malaria elimination. The first field trials are expected in 5-10 years in Uganda, Mali or Burkina Faso. In preparation, regional and international actors are developing risk governance guidelines which will delineate the framework for identifying and evaluating risks. Scientists and bioethicists have called for African stakeholder involvement in these developments, arguing the knowledge and perspectives of those people living in malaria-afflicted countries is currently missing. However, few African stakeholders have been involved to date, leaving a knowledge gap about the local social-cultural as well as ecological context in which gene drive mosquitoes will be tested and deployed. This study investigates and analyses Ugandan stakeholders' hopes and concerns about gene drive mosquitoes for malaria control and explores the new directions needed for risk governance. METHODS: This qualitative study draws on 19 in-depth semi-structured interviews with Ugandan stakeholders in 2019. It explores their hopes for the technology and the risks they believed pertinent. Coding began at a workshop and continued through thematic analysis. RESULTS: Participants' hopes and concerns for gene drive mosquitoes to address malaria fell into three themes: (1) ability of gene drive mosquitoes to prevent malaria infection; (2) impacts of gene drive testing and deployment; and, (3) governance. Stakeholder hopes fell almost exclusively into the first theme while concerns were spread across all three. The study demonstrates that local stakeholders are able and willing to contribute relevant and important knowledge to the development of risk frameworks. CONCLUSIONS: International processes can provide high-level guidelines, but risk decision-making must be grounded in the local context if it is to be robust, meaningful and legitimate. Decisions about whether or not to release gene drive mosquitoes as part of a malaria control programme will need to consider the assessment of both the risks and the benefits of gene drive mosquitoes within a particular social, political, ecological, and technological context. Just as with risks, benefits-and importantly, the conditions that are necessary to realize them-must be identified and debated in Uganda and its neighbouring countries.

Experimental Efficacy of the Face Shield and the Mask against Emitted and Potentially Received Particles.

There is currently not sufficient evidence to support the effectiveness of face shields for source control. In order to evaluate the comparative barrier performance effect of face masks and face shields, we used an aerosol generator and a particle counter to evaluate the performance of the various devices in comparable situations. We tested different configurations in an experimental setup with manikin heads wearing masks (surgical type I), face shields (22.5 cm high with overhang under the chin of 7 cm and circumference of 35 cm) on an emitter or a receiver manikin head, or both. The manikins were face to face, 25 cm apart, with an intense particle emission (52.5 L/min) for 30 s. The particle counter calculated the total cumulative particles aspirated on a volume of 1.416 L In our experimental conditions, when the receiver alone wore a protection, the face shield was more effective (reduction factor = 54.8%), while reduction was lower with a mask (reduction factor = 21.8%) (p = 0.002). The wearing of a protective device by the emitter alone reduced the level of received particles by 96.8% for both the mask and face shield (p = NS). When both the emitter and receiver manikin heads wore a face shield, the protection allowed for better results in our experimental conditions: 98% reduction for the face shields versus 97.3% for the masks (p = 0.01). Face shields offered an even better barrier effect than the mask against small inhaled particles (<0.3 µm-0.3 to 0.5 µm-0.5 to 1 µm) in all configurations. Therefore, it would be interesting to include face shields as used in our experimental study as part of strategies to reduce transmission within the community setting.

How do the general population behave with facemasks to prevent COVID-19 in the community? A multi-site observational study.

OBJECTIVE: The appropriate use of facemasks, recommended or mandated by authorities, is critical to prevent the spread of COVID-19 in the community. We aim to evaluate frequency and quality of facemask use in general populations. METHODS: A multi-site observational study was carried out from June to July 2020 in the west of France. An observer was positioned at a predetermined place, facing a landmark, and all individual passing between the observer and the landmark were included. The observer collected information on facemask use (type, quality of positioning), location and demographic characteristics. RESULTS: A total of 3354 observations were recorded. A facemask was worn by 56.4% (n = 1892) of individuals, including surgical facemasks (56.8%, n = 1075) and cloth masks (43.2%, n = 817). The facemask was correctly positioned in 75.2% (n = 1422) of cases. The factors independently associated with wearing a facemask were being indoors (adjusted odds ratio [aOR], 2.7; 95% confidence interval [CI] 2.28-3.19), being in a mandatory area (aOR, 6.92; 95% CI 5-9.7), female gender (aOR, 1.75; 95% CI 1.54-2.04), age 41-65 years (aOR, 1.7; 95% CI 1.43-2.02) and age > 65 years (aOR, 2.28; 95% CI 1.83-2.85). The factors independently associated with correct mask position were rural location (aOR, 1.38; 95% CI 1.07-1.79), being in an indoor area (aOR, 1.85; 95% CI 1.49-2.3), use of clothmask (aOR, 1.53; 95% CI 1.23-1.91), and age > 40 years (aOR, 1.75 95%CI 1.37-2.23). CONCLUSIONS: During the initial phase of the COVID-19 pandemic, the frequency and quality of facemask wearing remained low in the community setting. Young people in general, and men in particular, represent the priority targets for information campaigns. Simplifying the rules to require universal mandatory facemasking seemed to be the best approach for health authorities.

Unmasking the unmasked.

Facial maskings have been part of the human story since time began, and the reasons for their needs and the materials that went into their making would vary according to the reasons and materials available. The health-related needs took centuries to become established, but not until the germ theory of disease became recognized. The facial mask, seen as an essential defensive tool for prevention of respiratory transmitted disease continues to be the prime personal protective piece of equipment. With air-born contaminations, such as the present pandemic SARS- CoV-2 viral infestation, why would there be opposition to the use of this personal protective cover of our airways, when until an immunologic answer is available, it is the best single prevention we have. When supported with other measures, like distancing, washing and non-crowding, society would be much safer and secure, with probable less acute and drastic outcomes due to the spread of this virus.

Family medicine practitioners' stress during the COVID-19 pandemic: a cross-sectional survey.

BACKGROUND: The COVID-19 pandemic has shaken the world in early 2020. In France, General Practitioners (GPs) were not involved in the care organization's decision-making process before and during the first wave of the COVID-19 pandemic. This omission could have generated stress for GPs. We aimed first to estimate the self-perception of stress as defined by the 10-item Perceived Stress Score (PSS-10), at the beginning of the pandemic in France, among GPs from the Auvergne-Rhône-Alpes, a french administrative area severely impacted by COVID-19. Second, we aimed to identify factors associated with a self-perceived stress (PSS-10 ≥ 27) among socio-demographic characteristics of GPs, their access to reliable information and to personal protective equipment during the pandemic, and their exposure to well established psychosocial risk at work. METHODS: We conducted an online cross-sectional survey between 8th April and 10th May 2020. The self-perception of stress was evaluated using the PSS-10, so to see the proportion of "not stressed" (≤20), "borderline" (21 ≤ PSS-10 ≤ 26), and "stressed" (≥27) GPs. The agreement to 31 positive assertions related to possible sources of stress identified by the scientific study committee was measured using a 10-point numeric scale. In complete cases, factors associated with stress (PSS-10 ≥ 27) were investigated using logistic regression, adjusted on gender, age and practice location. A supplementary analysis of the verbatims was made. RESULTS: Overall, 898 individual answers were collected, of which 879 were complete. A total of 437 GPs (49%) were stressed (PSS-10 ≥ 27), and 283 GPs (32%) had a very high level of stress (PSS-10 ≥ 30). Self-perceived stress was associated with multiple components, and involved classic psychosocial risk factors such as emotional requirements. However, in this context of health crisis, the primary source of stress was the diversity and quantity of information from diverse sources (614 GPs (69%, OR = 2.21, 95%CI [1.40-3.50], p < 0.001). Analysis of verbatims revealed that GPs felt isolated in a hospital-based model. CONCLUSION: The first wave of the pandemic was a source of stress for GPs. The diversity and quantity of information received from the health authorities were among the main sources of stress.

Estimating the risk of outbreaks of COVID-19 associated with shore leave by merchant ship crews: simulation studies for New Zealand.

AIM: We aimed to estimate the risk of COVID-19 outbreaks in a COVID-19-free destination country (New Zealand) associated with shore leave by merchant ship crews who were infected prior to their departure or on their ship. METHODS: We used a stochastic version of the SEIR model CovidSIM v1.1 designed specifically for COVID-19. It was populated with parameters for SARS-CoV-2 transmission, shipping characteristics and plausible control measures. RESULTS: When no control interventions were in place, we estimated that an outbreak of COVID-19 in New Zealand would occur after a median time of 23 days (assuming a global average for source country incidence of 2.66 new infections per 1,000 population per week, crews of 20 with a voyage length of 10 days and 1 day of shore leave per crew member both in New Zealand and abroad, and 108 port visits by international merchant ships per week). For this example, the uncertainty around when outbreaks occur is wide (an outbreak occurs with 95% probability between 1 and 124 days). The combination of PCR testing on arrival, self-reporting of symptoms with contact tracing and mask use during shore leave increased this median time to 1.0 year (14 days to 5.4 years, or a 49% probability within a year). Scenario analyses found that onboard infection chains could persist for well over 4 weeks, even with crews of only 5 members. CONCLUSION: This modelling work suggests that the introduction of SARS-CoV-2 through shore leave from international shipping crews is likely, even after long voyages. But the risk can be substantially mitigated by control measures such as PCR testing and mask use.

A comparison of the value of two machine learning predictive models to support bovine tuberculosis disease control in England.

Nearly a decade into Defra's current eradication strategy, bovine tuberculosis (bTB) remains a serious animal health problem in England, with c.30,000 cattle slaughtered annually in the fight against this insidious disease. There is an urgent need to improve our understanding of bTB risk in order to enhance the current disease control policy. Machine learning approaches applied to big datasets offer a potential way to do this. Regularized regression and random forest machine learning methodologies were implemented using 2016 herd-level data to generate the best possible predictive models for a bTB incident in England and its three surveillance risk areas (High-risk area [HRA], Edge area [EA] and Low-risk area [LRA]). Their predictive performance was compared and the best models in each area were used to characterize herds according to risk. While all models provided excellent discrimination, random forest models achieved the highest balanced accuracy (i.e. average of sensitivity and specificity) in England, HRA and LRA, whereas the regularized regression LASSO model did so in the EA. The time since the last confirmed incident was resolved was the only variable in the top-ten ranking in all areas according to both types of models, which highlights the importance of bTB history as a predictor of a new incident. Risk categorisation based on Receiver Operating Characteristic (ROC) analysis was carried out using the best predictive models in each area setting a 99 % threshold value for sensitivity and specificity (97 % in the LRA). Thirteen percent of herds in the whole of England as well as in its HRA, 14 % in its EA and 31 % in its LRA were classified as high-risk. These could be selected for the deployment of additional disease control measures at national or area level. In this way, low-risk herds within the area considered would not be penalised unnecessarily by blanket control measures and limited resources be used more efficiently. The methodology presented in this paper demonstrates a way to accurately identify high-risk farms to inform a targeted disease control and prevention strategy in England that supplements existing population strategies.
