Obsessive-compulsive disorder is characterized by the presence of either obsessions or compulsions, but more commonly by both symptoms that can cause marked impairment or distress.
Obsession is a recurrent, persistent, intrusive, unwanted thought, image or urge that cause distressing emotions (eg anxiety and disgust).
Compulsion is a repetitive behavior or mental act that the person feels driven to perform, in order to lessen the distress caused by the obsession.
Anxiety is the central feature of obsessive-compulsive disorder.
A recent cross-sectional study shows that the mental health burden (ie, symptoms of depression, anxiety, insomnia, acute stress) associated with coronavirus disease 2019 (COVID-19) is considerable in China, particularly among individuals with confirmed or suspected COVID-19 and those exposed to patients with COVID-19 at work.
