“…Research in response to the 2003 SARS outbreak and its impact on people who are homeless identified challenges in communicating public health messages with marginalized populations and in providing space for screening or quarantining ( Leung, 2008 ). Another report identified low incidence of H1N1 among marginalized populations such as sex workers; its authors suggested that social marginalization may have had a protective effect against infection ( Rodwell et al, 2010 ).…”

“…Moreover, among the homeless people included during the 2011 snapshot, the rate of seasonal influenza vaccination was reported as 35.6% (data not shown), which was lower than the estimated influenza vaccination coverage in persons aged less than 65 years with an underlying condition in France in January 2011 (46.6%) [ 12 ]. Recently, a study suggested that the social isolation of homeless people might have been protective against pandemic influenza 2009 [ 5 ].…”

Respiratory viruses within homeless shelters in Marseille, France

et al. 2014

BackgroundHomeless shelters are identified as places where humans are at high risk of acquiring respiratory disease. We previously reported the prevalence of the main respiratory diseases affecting a population of homeless in Marseille, France. Here, we investigated the prevalence of 10 respiratory viruses in a similar homeless population during 2 successive winter seasons.FindingsFollowing a clinical examination, we collected nasal specimens from which the RT-PCR detection of 10 respiratory viruses was performed through snapshot investigations. Among the 265 patients included, 150 (56.6%) reported at least one respiratory symptom of which 13 (8.7%) had positive swabs for at least one respiratory virus, and 115 patients reported any respiratory symptom of which 10 (8.7%) had positive swabs for respiratory virus. Overall, 23 patients had positive swabs for at least one respiratory virus. Human rhinovirus (HRV) was the predominant virus (13 isolates) followed by enteroviruses (3), human metapneumovirus (2), human coronavirus OC43 (2), 229E virus (2) and human respiratory syncytial virus subtype B (1). Among the patients infected with HRV, 10 were collected during the same snapshot.ConclusionsAlthough one half of the patients reported respiratory symptoms, the prevalence of respiratory viruses was within the range of that previously described in adult asymptomatic patients outside the homeless community. Most HRV-positive swabs were collected during the same snapshot suggesting a local outbreak. No influenza viruses were found despite the fact that one half of the patients were investigated during the peak of the seasonal influenza epidemic in Marseille.

“…Four PCR-based prevalence surveys conducted among 1103 homeless or persons from marginalised populations between 2005 and 2018 fulfilled the eligibility criteria [2, 15, 84, 85]. Three were conducted among adult sheltered homeless persons in Marseille, France, and one was conducted among marginalised populations, including homeless persons, in Tijuana, Mexico.…”

“…Three were conducted among adult sheltered homeless persons in Marseille, France, and one was conducted among marginalised populations, including homeless persons, in Tijuana, Mexico. Three studies were conducted in adults (mean age: 35-44 years, range 18-84 years) [2, 15, 84] and one in a population comprising children and adults (mean age: 41 years, range 7-76 years) [85]. These studies reported a 1.0-3.0% rate of influenza nasopharyngeal carriage among sheltered homeless persons.…”

Background. Homelessness may result in the breakdown of regular health services, including routine vaccination programmes. A literature review was conducted to describe vaccine-preventable diseases (VPD) other than tuberculosis in homeless populations and to summarize vaccination recommendations in homeless people. Methods. We followed Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. We searched peer-reviewed literature published in English, French or Spanish reporting the outbreak of VPD or VPD prevalence in both infant and adult homeless populations published between 1980 and 2020, using PubMed/Medline, SciELO, Google Scholar, and Web of Science databases. Relevant information from the studies was charted in Microsoft Excel and results were summarised using a descriptive analytical method. Results. Seventy-five articles were included. A high prevalence of past HBV and HAV infections were observed through serosurveys, mostly in high income countries or high-middle income countries (USA, Canada, France, Iran or Brazil). Nine outbreaks of HAV infection were also reported, with lethality rates ranging from 0-4.8%. The studies discussed numerous risk factors positively associated with HBV infection, including older age, homosexual or bisexual practice, injected drug use (IDU), and, with HAV infection including IDU, having sexual partner(s) with a history of unspecified hepatitis, insertive anal penetration, or originating from a country with a high prevalence of anti-HAV antibody. Eleven outbreaks of pneumococcal infection affecting homeless persons were reported in Canada and USA, with lethality rates from 0-15.6%. Five diphtheria outbreaks were reported. Vaccination status was rarely documented in these studies. Conclusions. The literature suggests that homeless populations generally experience a higher VPD burden and lower immunisation rates. The findings suggest the need for a national vaccination programme and planning for delivering vaccines in this population.
