Based on his experience in the Democratic Republic of the Congo with Ebola,Ryan has said that while physical distancing,lock-downs,and movement restrictions will stop the spread of COVID-19,eradicating the virus will require large scale public health interventions with a focus on the central tenets of containment:community-based surveillance,contact tracing,isolation,and quarantine.

In 2025 the WHO announced that Ryan was being dropped from the executive leadership team,a decision for which it cited a funding crisis initiated by US withdrawal,and consequently a reduced salary budget,as well as a desire for gender and regional balance among leaders. [18]
