Plagues, pandemics and epidemics in Irish history prior to COVID-19 (coronavirus): what can we learn?

Objectives: This paper seeks to provide a brief overview of epidemics and pandemics in Irish history and to identify any lessons that might be useful in relation to psychiatry in the context of COVID-19. Methods: A review of selected key reports, papers and publications related to epidemics and pandemics in Irish history was conducted. Results: Viruses, epidemics and pandemics are recurring features of human history. Early Irish sources record a broad array of plagues, pandemics and epidemics including bubonic plague, typhus, cholera, dysentery and smallpox, as well as an alleged epidemic of insanity in the 19th century (that never truly occurred). Like the Spanish flu pandemic (1918-20), COVID-19 (a new coronavirus) presents both the challenge of the illness itself and the problems caused by the anxiety that the virus triggers. Managing this anxiety has always been a challenge, especially with the Spanish flu. People with mental illness had particularly poor outcomes with the Spanish flu, often related to the large, unhygienic mental hospitals in which so many were housed. Conclusions: Even today, a full century after the Spanish flu pandemic, people with mental illness remain at increased risk of poor physical health, so it is imperative that multi-disciplinary care continues during the current outbreak of COVID-19, despite the manifest difficulties involved. The histories of previous epidemics and pandemics clearly demonstrate that good communication and solidarity matter, now more than ever, especially for people with mental illness.
