Relevant documents available in selected websites were searched. The data generated were compiled, and information was synthesised within the WHO framework for critical preparedness, readiness and response actions against COVID-19. Further, scenarios of “no cases” and “sporadic cases” were analysed against the actions and priority areas of work of said framework.Results: Study revealed differences in implementation approach of strategic actions and priority areas of work, such as in terms of activation, timeliness of implementing emergency response plans, variations in case management strategies as seen in contact tracing, management of asymptomatic contacts, isolation, quarantine and selection of cohort for laboratory investigation. Besides, gaps were found in availability and activation of business continuity plans.Conclusion: Global political and health authorities need much robust mechanisms for preparedness, response and coordination of contagious diseases with similar nature.
