More than a third of the world's population is currently living under lockdown due to the coronavirus pandemic. Lockdown measures have been in place in many countries for several weeks. The health authorities are waging war against COVID-19 and have to provide information to the public on it while facing many unknowns about the virus. What impact does this have on mental health? What impact can lockdown have upon a population? What psychological impact will this lockdown have on elderly people living in nursing and care homes in Belgium and EHPADs France? We are not aware of any French-language research which has been published on the psychological aspects of the coronavirus among the population. We will try, through this article, to approach the psychological impact upon nursing staff and residents within nursing homes.
