Participatory development and implementation of inclusive digital health communication on COVID-19 with homeless people

Introduction: People experiencing homelessness (PEH) are disproportionally affected by the COVID-19 pandemic. The realities of their daily lives have been given little consideration in the pandemic response. They are not represented in existing health information campaigns, and many are structurally excluded from digital information. The project aimed to develop inclusive COVID-19-information material to strengthen infection prevention and control of PEH. Material and methods: In a participatory process, PEH were involved in the planning, production, and evaluation of poster and video information material on COVID-19. Various stakeholders were consulted for external supervision. Service providers all over Germany were informed about the material that could be ordered free of charge. For the evaluation, semi-structured interviews with homeless service providers and PEH were conducted, and the online views of the videos were measured. Results: Sixteen PEH participated actively in the project. Two COVID-19-information videos were launched in 5 languages in February 2021. Posters promoting vaccination against COVID-19 were produced in 9 languages. As of May 2022, the videos have been viewed more than 2,000 times. A total of 163 service providers for PEH and public institutions received the posters, thereof 72 upon request. Twelve service providers and 8 PEH participated in the evaluation. They pointed out the lack of targeted information material for PEH. The consideration of the concerns and the diverse representation of PEH was perceived as particularly important. Most of the service providers were unable to show the videos due to technical and spatial limitations. Digital challenges for PEH, like the lack of and maintenance of a smart phone, became apparent. Conclusion: The cooperation of research, practice and the community were key factors for the realization of this project. Strong links to the community and the involvement of relevant stakeholders are indispensable when working with PEH. Exclusion from digital information is an increasingly important component of the structural marginalization of PEH. Digital inclusion for PEH and service providers can help to counteract social and health inequalities. The lessons learned through this project can contribute to strengthen participation of PEH and to consider their perspectives in future health communication strategies.Peer Reviewe

Treatment of a giant hepatic echinococcal cyst with percutaneous drainage and in vivo assessment of the protoscolicidal effect of praziquantel

Therapy choices for cystic echinococcisis (CE) are stage-specific: surgical, minimally invasive, medical or observation without intervention. PAIR (percutaneous aspiration, instillation of a scolicide, and re-aspiration) has been considered the treatment of choice for uncomplicated echinococcal liver cysts. However, PAIR carries the risk of toxic cholangitis or hypernatremia and that the cyst frequently refills with bile after withdrawing the catheter. We treated a patient with a giant CE 1 liver cyst with puncture drainage (PD) under albendazole coverage. Drainage enabled us to monitor the morphology of protoscolices under praziquantel (PZQ) co-medication. Protoscolices degenerated within 5 days of PZQ 50 mg/kg/d. The cyst cavity solidified with no evidence of reactivation or secondary spread. Percutaneous treatments can replace surgery in a significant number or cases with hepatic CE. PD allows to assess microscopically the viability of protoscolices under co-medication with PZQ-albendazole and to avoid the instillation of topical scolicides

Monitoring for COVID-19 by universal testing in a homeless shelter in Germany: a prospective feasibility cohort study

Background: Living conditions in homeless shelters facilitate the transmission of COVID-19. Social determinants and pre-existing health conditions place homeless people at increased risk of severe disease. Described outbreaks in homeless shelters resulted in high proportions of infected residents and staff members. In addition to other infection prevention strategies, regular shelter-wide (universal) testing for COVID-19 may be valuable, depending on the level of community transmission and when resources permit. Methods: This was a prospective feasibility cohort study to evaluate universal testing for COVID-19 at a homeless shelter with 106 beds in Berlin, Germany. Co-researchers were recruited from the shelter staff. A PCR analysis of saliva or self-collected nasal/oral swab was performed weekly over a period of 3 weeks in July 2020. Acceptability and implementation barriers were analyzed by process evaluation using mixed methods including evaluation sheets, focus group discussion and a structured questionnaire. Results: Ninety-three out of 124 (75%) residents were approached to participate in the study. Fifty-one out of the 93 residents (54.8%) gave written informed consent; thus 41.1% (51 out of 124) of all residents were included in the study. Among these, high retention rates (88.9-93.6%) of a weekly respiratory specimen were reached, but repeated collection attempts, as well as assistance were required. Around 48 person-hours were necessary for the sample collection including the preparation of materials. A self-collected nasal/oral swab was considered easier and more hygienic to collect than a saliva specimen. No resident was tested positive by RT-PCR. Language barriers were the main reason for non-participation. Flexibility of sample collection schedules, the use of video and audio materials, and concise written information were the main recommendations of the co-researchers for future implementation. Conclusions: Voluntary universal testing for COVID-19 is feasible in homeless shelters. Universal testing of high-risk facilities will require flexible approaches, considering the level of the community transmission, the available resources, and the local recommendations. Lack of human resources and laboratory capacity may be a major barrier for implementation of universal testing, requiring adapted approaches compared to standard individual testing. Assisted self-collection of specimens and barrier free communication may facilitate implementation in homeless shelters. Program planning must consider homeless people's needs and life situation, and guarantee confidentiality and autonomy

A COVID-19 isolation facility for people experiencing homelessness in Berlin, Germany: a retrospective patient record study

Introduction: People experiencing homelessness (PEH) are disproportionately affected by the COVID-19 pandemic. For many PEH it is impossible to isolate due to the lack of permanent housing. Therefore, an isolation facility for SARS-CoV-2 positive PEH was opened in Berlin, Germany, in May 2020, offering medical care, opioid and alcohol substitution therapy and social services. This study aimed to assess the needs of the admitted patients and requirements of the facility. Materials and methods: This was a retrospective patient record study carried out in the isolation facility for PEH in Berlin, from December 2020 to June 2021. We extracted demographic and clinical data including observed psychological distress from records of all PEH tested positive for SARS-CoV-2 by RT-PCR. Data on duration and completion of isolation and the use of the facilities' services were analyzed. The association of patients' characteristics with the completion of isolation was assessed by Student's t-test or Fisher's exact test. Results: A total of 139 patients were included in the study (89% male, mean age 45 years, 41% with comorbidities, 41% non-German speakers). 81% of patients were symptomatic (median duration 5 days, range 1-26). The median length of stay at the facility was 14 days (range 2-41). Among the patients, 80% had non-COVID-19 related medical conditions, 46% required alcohol substitution and 17% opioid substitution therapy. Three patients were hospitalized due to low oxygen saturation. No deaths occurred. Psychological distress was observed in 20%, and social support services were used by 65% of PEH. The majority (82%) completed the required isolation period according to the health authority's order. We did not observe a statistically significant association between completion of the isolation period and sociodemographic characteristics. Conclusion: The specialized facility allowed PEH a high compliance with completion of the isolation period. Medical care, opioid and alcohol substitution, psychological care, language mediation and social support are essential components to address the specific needs of PEH. Besides contributing to infection prevention and control, isolation facilities may allow better access to medical care for SARS-CoV-2 infected PEH with possibly positive effects on the disease course

Dengue outbreak among travellers returning from Cuba-GeoSentinel surveillance network, January-September 2022

Increasing numbers of travellers returning from Cuba with dengue virus infection were reported to the GeoSentinel Network from June through September 2022, reflecting an ongoing local outbreak. This report demonstrates the importance of travellers as sentinels of arboviral outbreaks and highlights the need for early identification of travel-related dengue

SARS-CoV-2 Infection, Risk Perception, Behaviour and Preventive Measures at Schools in Berlin, Germany, during the Early Post-Lockdown Phase: A Cross-Sectional Study

Briefly before the first peak of the COVID-19 pandemic in Berlin, Germany, schools closed in mid-March 2020. Following re-opening, schools resumed operation at a reduced level for nine weeks. During this phase, we aimed at assessing, among students and teachers, infection status, symptoms, individual behaviour, and institutional infection prevention measures. Twenty-four primary and secondary school classes, randomly selected across Berlin, were examined. Oro-nasopharyngeal swabs and capillary blood samples were collected to determine SARS-CoV-2 infection (PCR) and specific IgG (ELISA), respectively. Medical history, household characteristics, leisure activities, fear of infection, risk perception, hand hygiene, facemask wearing, and institutional preventive measures were assessed. Descriptive analysis was performed. Among 535 participants (385 students, 150 staff), one teenager was found to be infected with SARS-CoV-2 (0.2%), and seven individuals exhibited specific IgG (1.3%). Compared to pre-pandemic times, screen time (e.g., TV, gaming, social media) increased, and the majority of primary school students reported reduced physical activity (42.2%). Fear of infection and risk perception were relatively low, acceptance of adapted health behaviors was high. In this post-lockdown period of low SARS-CoV-2 incidence in Berlin, individual and school-level infection prevention measures were largely adhered to. Nevertheless, vigilance and continued preventive measures are essential to cope with future pandemic activity

Travel-related infections presenting in Europe: A 20-year analysis of EuroTravNet surveillance data.

Funder: Centers for Disease Control and PreventionBACKGROUND: Disease epidemiology of (re-)emerging infectious diseases is changing rapidly, rendering surveillance of travel-associated illness important. METHODS: We evaluated travel-related illness encountered at EuroTravNet clinics, the European surveillance sub-network of GeoSentinel, between March 1, 1998 and March 31, 2018. FINDINGS: 103,739 ill travellers were evaluated, including 11,239 (10.8%) migrants, 89,620 (86.4%) patients seen post-travel, and 2,880 (2.8%) during and after travel. Despite increasing numbers of patient encounters over 20 years, the regions of exposure by year of clinic visits have remained stable. In 5-year increments, greater proportions of patients were migrants or visiting friends and relatives (VFR); business travel-associated illness remained stable; tourism-related illness decreased. Falciparum malaria was amongst the most-frequently diagnosed illnesses with 5,254 cases (5.1% of all patients) and the most-frequent cause of death (risk ratio versus all other illnesses 2.5:1). Animal exposures requiring rabies post-exposure prophylaxis increased from 0.7% (1998-2002) to 3.6% (2013-2018). The proportion of patients with seasonal influenza increased from zero in 1998-2002 to 0.9% in 2013-2018. There were 44 cases of viral haemorrhagic fever, most during the past five years. Arboviral infection numbers increased significantly as did the range of presenting arboviral diseases, dengue and chikungunya diagnoses increased by 2.6% and 1%, respectively. INTERPRETATION: Travel medicine must adapt to serve the changing profile of travellers, with an increase in migrants and persons visiting relatives and friends and the strong emergence of vector-borne diseases, with potential for further local transmission in Europe. FUNDING: This project was supported by a cooperative agreement (U50CK00189) between the Centers for Disease Control and Prevention to the International Society of Travel Medicine (ISTM) and funding from the ISTM and the Public Health Agency of Canada
