“…In our study, homeless people were characterised by a high proportion of migrants, a high proportion of smokers, and one third lacked health insurance coverage which is in line with previous surveys conducted in Marseille homeless shelters [ 3 – 5 ] and with surveys conducted in others European cities such as Frankfurt (Germany) [ 8 ] and Geneva (Switzerland) [ 6 ].…”

“…In 2005, an APTB screening campaign was conducted among 221 homeless people in Marseille, using CXRs, and reported a 0.9% rate of infection [ 11 ]. During the 2013–2018 period, we conducted 1-day cross-sectional surveys among 617 sheltered homeless people, using various microbiological investigations (qPCR of sputum or stools, sputum culture), and found no cases of APTB [ 3 ]. These results are in line with the 0–2% APTB prevalence reported among homeless populations in western European countries during the 2000–2019 period [ 3 , 6 , 12 ].…”

These results are in line with the 0–2% APTB prevalence reported among homeless populations in western European countries during the 2000–2019 period [ 3 , 6 , 12 ]. As in our preliminary survey, conducted in 2018, we found a higher prevalence of participants with a positive screening result (9.2% and 12.2%, respectively) than in the study by Janssens et al (4.1%).…”

“…Nevertheless, concentrated epidemics continue to occur among hard-to-reach groups such as homeless people and migrants [ 1 , 2 ]. Homeless people accounted for 7% of all new ATPB cases in Marseille (France) in 2016, while the homeless population in Marseille represents only around 0.2% of the population [ 3 ]. Over the past two decades, we have seen a change in the sheltered homeless population in Marseille, with a rising proportion of migrants [ 4 ].…”

“…In a preliminary study conducted by our team in 2018, in two Marseille homeless shelters, we showed that the use a short questionnaire aiming at screening for APTB [ 6 ] was well accepted by both homeless persons and medical staff during Chest X-ray (CXR)-based TB screening campaigns [ 3 ]. In this paper, we report the results of cross-sectional 1-day surveys conducted at these two Marseille homeless shelters in 2019, where all participants were investigated using questionnaire, chest radiography and microbiological examination of respiratory samples, with the aim of assessing the reliability of this screening questionnaire in a population of sheltered homeless people.…”

We aimed to assess the reliability of a screening questionnaire for Active Pulmonary Tuberculosis (APTB) in a population of sheltered homeless persons (HP). Participants from two homeless shelters completed a questionnaire specially designed to identify patients at high-risk of APTB (available at www.tb-screen.ch ), underwent a Chest X-ray (CXR), and provided sputum samples. Computed Tomography (CT) scanning was subsequently performed on those which had images consistent with APTB. Microscopical examination, real-time polymerase chain reaction (qPCR) and culture testing were applied for Mycobacterium tuberculosis complex detection. Additionally, we retrospectively selected 16 HP hospitalised in our hospital between 2017 and 2019 with biologically confirmed tuberculosis and typical CXR images, and retrospectively documented a screening questionnaire by reviewing their medical files. Overall, the population ( n = 383 HP) was predominantly migrants (87%). Forty-seven individuals (11.7%) had positive screening questionnaire scores and four (2.4%) displayed abnormal CXR features consistent with APTB. Three of them three underwent CT scanning that ruled out APTB and one was lost to follow-up. None tested positive through microbiological investigation. Fifteen (of 16, 93.8%) hospitalised patients with biologically confirmed APTB had a positive screening questionnaire score. The sensitivity and specificity of questionnaire for confirmed APTB were 93.8% and 87.7%, respectively. Screening questionnaires can be used as a first assessment tool in people arriving at homeless shelters and to refer those screening positive for a CXR.

We review the most recent work conducted by our group on the circulation of infectious agents in mobile populations, including pilgrims participating in the Hajj (Mecca, Saudi Arabia) and the Grand Magal of Touba (Senegal) pilgrimages, homeless people, and medical students participating in an elective abroad. Using a similar epidemiological study design with standardized questionnaires and molecular assays allows comparison of different populations of travelers. The main infectious pathogens and antibiotic resistance genes linked to travel were identified in certain specific populations of travelers, as well as in a group of homeless migrant people in Marseille. The role of several risk factors has also been demonstrated, allowing identifying individuals at increased risk of disease or pathogen carriage on which to base targeted preventive measures. Such results, together with those obtained through international surveillance networks allow better description of the epidemiology of travel-associated infectious diseases.
