**1. Introduction**

Coronavirus Disease 2019 [COVID-19] appeared in Wuhan, China in December 2019 and spread rapidly throughout the country and then the world, so today we are facing a pandemic [1]. From 15 April 2020 to 21 July 2022, a number of 571,833,637 Covid-19 patients were identified in the world, of which 6,396,439 deaths due to the virus occurred [2]. So far, this virus has caused 108,721,646 total infected cases and 1,499,042 total deaths in the USA. The most cases and mortality of 212,621,751 and 1,868,908 respectively, occurred after this pandemic in Europe. Also, in Asia, there have been 165,724,865 total cases and 1,444,347 total deaths due to this virus [2].

The ambiguous nature of the disease and its unfamiliarity, as well as the implementation of quarantine measures that were strictly applied in some countries, such as China, to keep a large number of people in isolation, increased the burden of the disease and affected many aspects of their lives. It has caused widespread psychological problems such as panic disorder, anxiety, and depression along with physical problems [3]. Sirati Nir mentions according to Wang & et al "Anxiety caused by the fear of being in the community causes people not to enter shopping centers, students do not enter educational centers, and workers and tourists do not enter work and leisure institutions, and these cases lead to feelings of reduced independence and stress and worries about income and security occupations and other issues have led to psychological problems, with governments in China, Singapore, and Australia expressing concern about the psychological side effects of Covid-19, and the longterm effects of this isolation and fear in society are considered serious threats to mental health" [4].

Psychiatric disorders are highly prevalent in medical illnesses. According to world health organization (WHO) figures, at least 52 million people worldwide suffer from severe mental illness and 150 million from severe mental disorders [5]. A mental disorder is a behavioral and psychological pattern that occurs in a person and is associated with a functional disorder caused by a biological disorder [social, psychological, genetic, physical, or chemical] [6]. In addition to the suffering and limitations that it creates for the individual, mental illness causes discrimination in social and professional activities due to the stigma of mental illness and thus imposes a heavy financial burden on society and the individual [7]. In a systematic review, it was reported that the quality of life of communities that suffer from Covid-19 is greatly reduced due to social distance [8].

Also, epidemic outbreaks can cause significant psychological stress that may lead to adverse effects on the quality of life and overall mental health of employees, which emphasizes the need to establish psychological support programs for medical workers during infectious disease outbreaks. It has been suggested that social support may be a powerful strategy to reduce the negative consequences of mental status faced by medical workers during infectious disease epidemics [9, 10]. In research on previous epidemics in recent years, a wide range of psychosocial effects on individuals at the individual, community, and Internationally reported at the time of the outbreak of infection [11]; so the flu outbreak, about 3–10% of the general public were concerned about being infected with the virus and the disease [12]. In the study of the Ebola outbreak, a wide range of psychosocial effects on individuals during the outbreak of infection were reported at the individual, national and international levels, and at the individual level, individuals seeking high fears of illness or death, feeling weak. They had experienced disability and social stigma [11]. Closing schools and businesses increased the negative emotions that people experienced. For example, during the outbreak of SARS, significant psychological effects were reported, especially in younger people than in older people [13, 14].

### **2. The importance of the issue**

Because the coronavirus COVID-19 is a public health emergency of international concern, it poses a challenge to psychological resilience. According to the evidence ordinary people, patients, staff, and family members of patients and health workers are exposed to the psychological damage caused by the epidemic of the virus.

Understanding the mental state of people exposed to psychological disorders can help professionals to provide targeted psychological interventions to improve the patient's mental health. Also, it is necessary to provide evidence-based strategies to policymakers in any community to reduce the adverse psychological effects and psychiatric symptoms during an epidemic, which can lead to restrictive measures to control and alleviate psychological problems following or during the COVID-19 epidemic [15]. Due to the onset of the Covid-19 epidemic in China, evidence-based assessments and mental health interventions for patients and health care staff are relatively rare [16]. Therefore, conducting a systematic study by reviewing and combining all related documents can create a more complete picture of the dimensions of this problem in society. Coronavirus infection has been performed worldwide and has looked for symptoms such as depression, anxiety, insomnia and anxiety and potential risk factors associated with it, and can therefore provide a clear basis for intervention and implementation of mental health intervention policies for confronting this challenge efficiently and effectively.
