Dr Funmi Okunola MD conducts three interviews with 4 representatives of the World Health Organization -

Dr Maria Van Kerkhove PhD -Director of the Department of Epidemic & Pandemic Threat Management;

Dr Jamie Rylance MD - Clinical Lead for Long COVID and part of the Clinical Management Team of the Health Emergencies Program;

Cristiana Salvi - Regional Advisor for Community Resilience & Protection in the Health Security Division of WHO Europe;

Leonardo Palumbo - Technical Officer in Community Engagement in the Health Security Division of WHO Europe.

We talk about the WHO's support of Long COVID through advocacy, education research and community engagement and the steps the organization is taking to ensure Worldwide equity with regard to access to health resources for those living with Long COVID.
