A study conducted in Toronto, Canada, during the SARS outbreak examined the psychological effects of quarantine on 129 quarantined individuals. The results showed a high prevalence of psychological distress, with 28.9% reporting symptoms of posttraumatic stress disorder (PTSD) and 31.2% experiencing depressive symptoms. Longer quarantine durations and exposure to someone with SARS were associated with increased PTSD and depressive symptoms. The study also found that individuals with lower household incomes experienced higher levels of psychological distress, suggesting the need for additional support for this group. Quarantine, while effective in containing infectious diseases, can have significant psychological, emotional, and financial impacts on individuals. The study highlighted the importance of understanding the psychological effects of quarantine to improve disease containment and minimize negative consequences for quarantined individuals, their families, and social networks. The research also found that many quarantined individuals felt isolated and experienced anxiety due to the lack of social contact and the stress of infection control measures. The study used validated psychological scales to assess distress levels and found that the mean IES-R score was 15.2 and the mean CES-D score was 13.0. These scores indicated that a significant proportion of quarantined individuals experienced symptoms of PTSD and depression. The study also found that individuals who wore masks all the time had higher distress scores, suggesting that strict adherence to infection control measures may increase psychological distress. The study's findings highlight the need for public health officials to be aware of the psychological effects of quarantine and to provide additional support to those at risk. The research also underscores the importance of improving public understanding of quarantine measures and the rationale behind them to reduce distress and enhance compliance. Despite its limitations, the study provides valuable insights into the psychological impact of quarantine and the need for further research to address the challenges associated with this public health measure.A study conducted in Toronto, Canada, during the SARS outbreak examined the psychological effects of quarantine on 129 quarantined individuals.
