Posttraumatic stress disorder (PTSD)

PTSD is a mental disorder that can happen after exposure to potentially psychologically traumatic events (e.g., actual or threatened death, natural disasters, violence).

Symptoms of PTSD include recurring and distressing memories, avoiding reminders of the event(s), and disturbed sleep.Footnote 2

PTSD and the COVID-19 pandemic

The COVID-19 pandemic has impacted individuals, families, and communities in many ways.
