The COVID-19 pandemic has hugely affected the world and human lives, the economy, and lifestyles. The pandemic control measures, such as lockdowns, forced many people to migrate from their destination to their source in various states, leading to increased vulnerability of migrants. The present review aimed to explore the different health, economic, and social impacts on internal migrants of India during the pandemic. The publications on internal migration and COVID-19 from India were retrieved from PubMed and Google Scholar using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 159 articles were extracted, of which 28 were reviewed. The articles published after March 1, 2020, were included in the review, irrespective of the design. Out of 28 articles, only half were original studies; the rest were either perspective, opinion, and review studies or editorial and commentary papers. Depression, anxiety, and stress due to job loss and lockdown were the major health issues documented. There was livelihood disturbance due to loss of income, such as inability to pay rent, loans, borrowing from relatives, and fear of its consequences. The migrants also faced stigma and discrimination from the villagers. The review also highlighted that although the government implemented various schemes to help the migrants, the majority were left out due to the non-availability of identity proof and ration cards. The safeguarding measures for these unregistered migrants must be facilitated to access health, economic, and social protection. Although various publications have focused on the mental health of the migrants, the socio-ecological aspects have been least explored, which calls for further studies. The literature on the impact of COVID-19 on other vulnerable populations like women and children and access to healthcare services is also scant, which needs to be explored further.
