The COVID-19 pandemic has not only had health, economic, and political impacts, but also significant psychosocial and mental health consequences worldwide. In this article, different documentation and studies on mental health were analyzed, with the aim of identifying the various problems detected during the pandemic. Methodologically, a narrative and integrative review of the scientific literature was carried out. In Latin America, the most recent studies have documented and made patent effects on the various vulnerized populations such as migrants, women, children, the elderly, people living with significant disabilities, people experiencing marked housing and food insecurity, and temporary workers laboring in what has been referred to as the informal economy. In light of this, it is proposed that addressing these issues should involve the coordination of transnational policies and the definition of an agenda of critical priorities to focus and address. For this to come about, it is important that the empirical evidence generated by regional epidemiological studies contribute to the design of public policies on mental health of the Latin American population, so that they reduce the negative effects as well as prevent the future consequences of a pandemic that is not yet over.
