The COVID-19 pandemic has brought to light tremendous gaps and issues faced by health systems globally . Commendable effort has been made to retain continuity of care for non-COVID-19 patients amidst the pandemic, particularly using technology-enhanced models of care . However, these efforts are not sufficient to tackle the impending challenges that health systems around the world will face next: (1) vaccine uptake and hesitancy; (2) a mental health crisis; and (3) post-COVID-19 migration . In this letter to the editor, explanation of why each of these issues is concerning and how each subsequent issue grows in severity is provided . Particular focus on the issue of post-COVID-19 migration is made, as this challenge is quite pressing to health systems but has yet to be explored thoroughly in the literature . Possible strategies for health system planners to consider are provided in this letter . Strategies include involving stakeholders such as patients and clinicians in deliberations and deployment of interventions, focussing efforts on adapting primary health systems, and building on technology-enhanced models of care where possible . By adhering to the recommendations made in this letter, health systems may be able to proactively deal with the identified challenges before they become crises of their own, post COVID-19.
