The COVID-19 pandemic has led to significant mental health consequences, including anxiety, depression, and stress. A review of existing literature reveals that these psychological issues are common among the general population, healthcare workers, and vulnerable groups such as older adults, the homeless, and pregnant women. The literature highlights the need for mental health services and social support to mitigate these adverse effects. Therapeutic interventions, including online counseling and telepsychiatry, have been proposed to address mental health needs during the pandemic. However, the quality of evidence is relatively low, and further research is needed to assess the impact in different countries and among specific vulnerable populations. The long-term mental health impact of COVID-19 may be severe, and a coordinated effort from the healthcare system is essential to manage it effectively.The COVID-19 pandemic has led to significant mental health consequences, including anxiety, depression, and stress.
