A review article assessing the psychosocial impact of COVID-19 stated that quarantined individuals and positive COVID-19 patients tend to suffer from loneliness, anxiety, panic, post-traumatic stress disorder, and depression. Researchers concluded that setting up mental health organizations specific for future pandemics for research and arranging awareness programs is desperately needed. 
A review article assessing the impact of COVID-19 on mental health found that fear of the unknown leads to higher anxiety level in both healthy people and those with pre-existing mental health problems, and that unjustified public fear may lead to discrimination and stigmatization of the illness.
These mental health concerns may evolve into long-lasting health problems, isolation and stigma. Researchers concluded that global health measures should be employed to address psychosocial stressors, particularly related to the use of isolation/quarantine, fear and vulnerability among the general population. 
A meta-analyses including studies assessing the prevalence of stress, anxiety and depression in the general population during the COVID-19 pandemic found that people with higher levels of education had greater levels of anxiety, depression, and stress. Previous medical conditions may contribute to increased anxiety levels. Researchers found that the prevalences of stress, anxiety, and depression, as a result of the pandemic in the general population, are 29.6%, 31.9% and 33.7% respectively.
