We read with interest Goodwin et al's paper on ‘Psychological distress after the Great East Japan Earthquake’,^{Reference Goodwin, Sugiyama, Sun, Aida and Ben-Ezra1} which featured in the March 2020 BJPsych themed issue on ‘Disasters and Trauma’. This is timely given the current climate when the UK and other nations of the world are grappling with the disastrous consequences of infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) otherwise known as coronavirus disease 2019 (COVID-19). Although the physical impact of the global pandemic is yet to be adequately quantified, the huge psychological and social burdens on human existence are issues we need to start addressing in order to be ahead of whatever curve we may end up with globally.^{Reference Holmes, O'Connor, Perry, Tracey and Wessely2}

With time, society will be dealing with the psychiatric impact (in extreme cases) or the psychological impact (in not so extreme cases) of COVID-19. Bereavement, grief, loss, separation, anxiety, fear, paranoia, adjustment reactions and depression are foreseeable after-effects when life starts to return to what we previously considered ‘normal everyday life’. Some degree of ‘antisocial’ behaviour will emerge with ‘social distancing’ becoming a norm, and physical distancing could become a weapon of subtle intimidation or bullying in the workplace or even at schools. Also, we cannot overlook supposedly minor conditions like anger or frustration fuelling the emergence or resurgence of violence against self, domestic violence and violence at the community level following such an impact on our daily lives. According to the charity Refuge, the National Domestic Abuse helpline has seen a 25% increase in calls and online requests for help since the lockdown.^{Reference Kelly and Morgan3} Recently, the UK Parliament's Home Affairs Select Committee called for removal of the time limit on prosecutions to ensure perpetrators of domestic abuse during the lockdown do not get away with their crimes.^{Reference Grierson4}

Currently, there is no physical war between nations but there is a fight to contain a crowned virus – although small, pathogenic and not human, it is nonetheless powerful enough to crash the world system to a large extent. Our concern is that in addition to the above, the worsening or re-emergence of previous mental health problems in the context of a lockdown situation, as well as the new onset of mental health problems once the limitations or containment of lockdown is over could potentially overload primary and secondary mental health services.

Mental health services at all levels, including psychological services in primary care, bereavement services and secondary mental health services therefore need to start preparing for post-lockdown demand for care by making arrangements for how they will manage increased demands for services. Mental health promotion should be launched now and after the COVID-19 pandemic to prevent an overloading of the National Health Service via the mental health services’ route. Proactive steps therefore need to be taken to make this overloading less likely. Will mental health services be prepared for the extra demands that will follow the aftermath of this pandemic? Only time will tell.
