BackgroundThe ongoing Syrian civil war has led to massive population displacements, leading to the reorganization of the asylum policies of several countries. Accordingly, like other European countries, the Swiss government has recently chosen to implement a specific resettlement program. This program is characterized by the fact that the whole nuclear family is granted a work and residence permit upon arrival, and benefits from enhanced integration services. The aim of the present project is to evaluate the effects of the Swiss resettlement program, with a special focus on mental health, while adopting a family perspective.MethodsThe outcomes of 15 Syrian families taking part in this program will be compared to those of 15 Syrian families that came to Switzerland through other means (i.e., following the usual asylum procedure, which is much more stressful and time consuming). Each family member above 8 years old will be invited to participate to a 3-wave longitudinal survey concerning the resettlement process: upon arrival in the collective shelters, six and 12 months later. Questionnaires will be used for the evaluation of participants’ mental health, risk behaviors, general health, romantic relationship, parent-child relationship, family functioning, parentification, social support, and social identities related to group belongingness.DiscussionThe findings of the present project will provide longitudinal information on Syrian refugees. A comprehensive approach will be adopted by screening potential difficulties that the sample may be faced with and potential strengths that participants may rely on. Accordingly, physical and mental health, as well as the quality of family functioning, the feeling of support and of belongingness to different groups will be evaluated.We will also compare the results of families who had the chance to immigrate through the Swiss resettlement program, to the results of families that did not. This comparison will allow the elaboration of hypotheses regarding adjusted asylum policies. Furthermore, it will enhance our knowledge regarding the impact of displacement on the family system. Indeed, although the role of the family for the well-being of adults and children has been established, surprisingly few studies have adopted this focus in the asylum field.

Background Seroprevalence and the proportion of people with neutralizing activity (functional immunity) against SARS-CoV-2 variants were high in early 2022. In this prospective, population- based, multi-region cohort study, we assessed the development of functional and hybrid immunity (induced by vaccination and infection) in the general population during this period of high incidence of infections with Omicron variants. Methods We randomly selected and assessed individuals aged ≥16 years from the general population in southern (n = 739) and north-eastern (n = 964) Switzerland in March 2022. We assessed them again in June/July 2022, supplemented with a random sample from western (n = 850) Switzerland. We measured SARS-CoV-2 specific IgG antibodies and SARS-CoV-2 neutralizing antibodies against three variants (ancestral strain, Delta, Omicron). Results Seroprevalence remained stable from March 2022 (97.6%, n = 1894) to June/July 2022 (98.4%, n = 2553). In June/July, the percentage of individuals with neutralizing capacity against ancestral strain was 94.2%, against Delta 90.8% and against Omicron 84.9%, and 50.6% developed hybrid immunity. Individuals with hybrid immunity had highest median levels of anti-spike IgG antibodies titres [4518 World Health Organization units per millilitre (WHO U/mL)] compared with those with only vaccine- (4304 WHO U/mL) or infection- (269 WHO U/mL) induced immunity, and highest neutralization capacity against ancestral strain (hybrid: 99.8%, vaccinated: 98%, infected: 47.5%), Delta (hybrid: 99%, vaccinated: 92.2%, infected: 38.7%) and Omicron (hybrid: 96.4%, vaccinated: 79.5%, infected: 47.5%). Conclusions This first study on functional and hybrid immunity in the Swiss general population after Omicron waves showed that SARS-CoV-2 has become endemic. The high levels of antibodies and neutralization support the emerging recommendations of some countries where booster vaccinations are still strongly recommended for vulnerable persons but less so for the general population.

Background The mechanism underlying the health care cost trajectories among asylum seekers is not well understood. In the canton of Vaud in Switzerland, a nurse-led health care and medical Network for Migrant Health (“Réseau santé et migration” RESAMI) has established a health care model focusing on the first year after arrival of asylum seekers, called the “community health phase”. This model aims to provide tailored care and facilitate integration into the Swiss health care system. The aim of this study is to explore different health care cost trajectories among asylum seekers during this phase and identify the associated factors. Methods We detected different patterns of health care cost trajectories using time-series clustering of longitudinal data of asylum seekers in the canton of Vaud in Switzerland. These data included all adult asylum seekers and recipients of emergency aid who entered the canton between 2012 and 2015 and were followed until 2018. The different clusters of health care cost trajectories were then described using a multinomial logistic regression model. Results We identified a concave, an upward trending, and a downward trending cluster of health care cost trajectories with different characteristics being associated with each cluster. The likelihood of being in the concave cluster is positively associated with coming from the Eastern Mediterranean region or Africa rather than Europe and with a higher share of consultations with an interpreter. The likelihood of being in the upward trending cluster, which accrued the highest costs, is positively associated with 20–24-year-olds rather than older individuals, coming from Europe than any other region and having a mental disorder. In contrast to the other two clusters, the likelihood of being in the downward trending cluster is positively associated with having contacted the RESAMI network within the first month after arrival, which might indicate the potential of early intervention. It is also positively associated with older age and living in a group lodge. Conclusions Asylum seekers are heterogeneous in terms of health care cost trajectories. Exploring these differences can help point to possible ways to improve the care and supporting services provided to asylum seekers. Our findings could indicate that early and patient-centered interventions might be well-suited to this aim.
