notify discriminatory acts and to support those affected by harmful misconceptions (Rzymski and Nowicki, 2020). Individuals in Economic Vulnerability As in natural hazards, the economically disadvantaged people seem to be more susceptible to the threat and more likely to be minced by it (Bavel et al., 2020). For instance, a study has shown that groups with lower income may have been performing less physical exercises during this period, due to less access to Internet and technological tools. This is evidence that, besides the economic impairment, these individuals are also more vulnerable to physical and psychological repercussions of social isolation (PeƧanha et al., 2020). Furthermore, there has been correlation between socioeconomic deprivation and ability to adopt preventive measures, enhancing the risk inequality (Atchison et al., 2020). Those living in informal settlements have particular stressors that decline their mental health. For instance, space constraints, violence and overcrowding implicates in decreased capability to adhere to the social distancing measures and, as a consequence, in increased fear of contamination (Corburn et al., 2020). Furthermore, basic needs such as access to water, waste collection, sewers and adequate housing may not be available. Moreover, most of the individuals living in slums are informal workers and, therefore, are more vulnerable to the economical impact of the pandemic (Corburn et al., 2020). Finally, racism, xenophobia and stigmatization of the poor have raised during the pandemic, which implicates in even worse outcomes regarding the mental health of these populations (Corburn et al., 2020). Homeless Individuals Homeless individuals compose another vulnerable group for contracting COVID-19 and for the psychological impact of the pandemic (Hsu et al., 2020; Khan et al., 2020; Mesa Vieira et al., 2020). First, this group faces difficulties in taking preventive measures for COVID-19, such as hand washing and self-isolation. Conversely, they are more prone to risky behaviors such as substance abuse and the sharing of needles (Wood et al., 2020). Second, many individuals have an increased prevalence of comorbidities and chronic diseases compared with people of similar age, including mental health disorders like bipolar disorder and schizophrenia (Khan et al., 2020; Mesa Vieira et al., 2020; Wood et al., 2020). Third, they face enhanced obstacles to receive treatment for previous medical conditions, especially considering their reduced accessibility to telehealth services (Wood et al., 2020). Prisoners The vulnerability of the prison population in the COVID-19 pandemic does not seem to be thoroughly explored by the scientific community (Hewson et al., 2020). Notwithstanding, this group of individuals comprise numerous risk factors for worse mental health outcomes secondary to the current circumstances. This magnified emotional impact is a result of several aspects. The frequency of pre-existing psychological disorders, neurodevelopmental health, substance misuse, suicide and self-harm is already increased in this group compared to the rest of the population (Hewson et al., 2020; Kothari et al., 2020). Moreover, as consequences of the COVID-19 pandemic, these individuals have been suffering with diminished social interaction with other inmates and outside visitors, suspension of jury trials and delay of court hearings, and recreational and occupational prison activities (Fovet et al., 2020; Hewson et al., 2020
