Infectious disease outbreaks have occurred sporadically over the centuries. The most significant ones of this century, as reported by the WHO, include the EVD epidemic, SARS pandemic, Swine Flu pandemic and MERS pandemic. The long-term mental health consequences of outbreaks are as profound as physical ones and can last for years post-outbreak. This highlights the need for enhancing the preparedness of pragmatic mental health service provision. Due to its magnitude, the novel COVID-19 pandemic has proven to be the most impactful. Compared to previous outbreaks, COVID-19 has also occurred at higher rates in frontline staff in addition to patients. Since COVID-19 is more contagious than earlier outbreaks, there is a need to identify infected people quickly and isolate them and their contacts. This is the current context in which mental health services including IAPT have had to operate. Evidently, IAPT services are a major mental health service provider in the UK which have demonstrated variability in their response to COVID-19. While some IAPT services quickly adapted their existing strengths and resources (e.g. remote working) other services were less prepared. To date there are no clear unitary guidelines on how IAPT services can use their pre-existing resources to respond to the long-term effects of outbreaks. In light of this, the current paper aims to reflect on the lessons learned from past outbreaks in order to consider how an enhanced remit of IAPT might integrate with other services to meet the long-term needs of patients and staff affected by COVID-19.
