Results: Among 70,512 migrants (91% males and 9% females, all <60years old) who landed in Italy during the observation period, 2,861 tested positive, with an incidence rate of 40.6 (39.1-42.1) cases per 1,000. In the same period, an incidence rate of 177.6 (177.5-177.8) has been recorded in the resident population, with an IR of 0.22 (0.22-0.23). 89.9% of cases were males and almost half (49.6%) belonged to the age group 25- 39years old. 99% of cases reported no symptoms, no relevant comorbidity has been reported and no cases have been hospitalized. Conclusions: Our findings clearly highlight the low rate of SARS-CoV-2 infection in migrants reaching Italy by sea with an incidence rate that is roughly a quarter of that of the resident population, encouraging the opportunity to investigate the reasons for such an observation. Moreover, our study confirms the ‘‘healthy migrant effect’’ in migrants reaching Italy by sea. Key messages:  Irregular migrants arriving in Italy did not increase the COVID-19 burden in the country, thus alarmism is not justified.  Further studies are needed to investigate the reasons for the lower incidence observed.

Although the European Union offers guidance on individual health assessment of refugees fleeing the war in Ukraine, assessment practice varies across host countries and even on national basis. Thus, the aim of this project was to identify and prioritize procedures for mental health assessment of Ukrainian refugee minors in Norway. Methods: This project applied a modified three-round-Delphi method. In a first step, the leading public health nurse and community physician in 40 municipalities across Norway were contacted via e-mail and asked to state who is in charge of health assessment, what is current assessing practice and what are the problems and needs. Answers were analysed and condensed and will be presented for rating in a second and third round. Results: Preliminary results from the first round suggest that most municipalities are currently in a planning phase with uncertainties surrounding who and how future assessments will be done. Public health nurses or general practitioners are often in charge of health assessments, but it is unclear if this includes age-adjusted mental health assessments. Conclusions: Preliminary results show that current practice in assessing mental health and psychosocial support for Ukranian refugee minors in Norway is very diverse. There is a need to evaluate and prioritize current procedures to assure an equal and age- adjusted procedures for all refugee minors, regardless of where they have resettled. Key messages:  Current practice in assessing mental health and psychosocial support among Ukrainian refugee minors is very diverse.  Assessment of mental health in Ukrainian refugees depends on infrastructure and local municipal resources.

However, there is still no evidence on the level of knowledge of these HIV prevention tools among immigrants from sub- Saharan Africa living in precarious situations, a population particularly affected by HIV. The aim of this study is to describe the knowledge of these tools in this population and analyse the factors associated with this knowledge. Methods: The data mobilized are from the Makasi interventional research that was conducted between 2018 and 2020 among immigrants from sub-Saharan Africa in precarious situations in the greater Paris area. Using data collected from 601 participants, we described levels of knowledge of HIV treatment effectiveness, treatment as prevention (TasP), post- exposure prophylaxis (PEP), and pre-exposure prophylaxis (PrEP), by sex with a chi2 test. We investigated factors associated with their knowledge with logistic regressions adjusted for sociodemographic characteristics, living condi- tions and sexual behaviors (p  0.2). Results: The population surveyed was predominantly men (76%), from West Africa (61%) and in a precarious situation: 69% were unemployed, 74% were undocumented, 46% had no health coverage and 13% were homeless. In this population, knowl- edge of antiretroviral treatments for HIV prevention was heterogeneous: the effectiveness of HIV treatment was well known (84%), but only half of the respondents (46%) were aware of TasP and very few knew about PEP and PrEP: 6% and 5% respectively. Multivariable-adjusted models showed that these tools was better known by educated people, those who had a social network in France, those who have had access to the health system and those who were exposed to sexual risks. Conclusions: While sub-Saharan African immigrants know the effectiveness of HIV treatment and use certain prevention tools such as HIV testing, they are not aware of PEP and PrEP. Key messages:  PEP and PrEP are two HIV prevention tools that are not well known by sub-Saharan African immigrants.  There is an urgent need to disseminate information about these prevention tools to immigrants.
