ABSTRACT
Background: The development of COVID-19 pandemic has affected all segments of the population;however, it had a significant impact on vulnerable subjects, such as in people experiencing homelessness. The aim of this study was to evaluate the prevalence of COVID-19 spread in homeless persons in the city of Rome, Italy. Design and Methods: Patients included in the study underwent a clinical evaluation and rapid antibody analysis on capillary blood for the presence of immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies to SARS-CoV-2 virus. Symptomatic patients were not included in the screening and immediately referred to local hospitals for further evaluation.
ABSTRACT
This review aimed to gather information about the biological effects of bovine colostrum (BC) supplementation for improving the respiratory health in humans and the potential role of bioactive molecules from BC as adjunctive therapy for SARS-CoV-2 infection (Coronavirus Disease 2019–COVID-19). Several studies have shown that BC supplementation is effective against infections and respiratory allergies, as well as in attenuating immunosuppression caused by intense exercise in high-performance athletes. The major immune system modulation proteins present in BC are immunoglobulins, lactoferrin and transforming growth factor-β (TGF-β). Studies have revealed that lactoferrin is effective in combating SARS-CoV-2. Hyperimmune colostrum may constitute an alternative way to produce specific antibodies against COVID-19. Based on the immune system boosting ability as well as anti-inflammatory, antioxidant and antiviral/antibacterial activities, we suggest that well designed, randomized, placebo-controlled, multicenter clinical trials should be done to verify the safety and effectiveness of BC supplements against SARS-CoV-2 infection. © 2021 The Author(s).

ABSTRACT
Homeless persons and migrants in precarious housing conditions are vulnerable populations that have been peculiarly impacted by the Coronavirus Disease 19 (COVID-19) pandemic. These populations are more at risk of contracting COVID-19 as they often find it difficult to adhere to public health directives and, if exposed, may be more susceptible to illness or death due to the higher prevalence of underlying physical and mental comorbidities compared to the general population. In addition, vulnerable populations may have limited access to essential diagnostics and treatments, thus leading to untreated COVID-19 cases and their development into more severe forms. Health, social and government agencies should collaborate to develop services that support these communities, in accordance with the World Health Organization principles. Migrant and homeless centers have a central role, as they provide a significant contribution to prevent infection spread and favor access to early medical treatment to those affected, thus preventing more severe forms of infection.
