From the search for a vaccine to strategies for exiting lock-down, the World Health Organisation is guiding the globe in the fight against COVID-19.

In an Ask The Agenda special Margaret Harris, Spokesperson for the World Health Organization (WHO) returns alongside Prof Karol Sikora, Dean of the University of Buckingham's medical school and former chief of the cancer programme at the WHO to answer your questions about the pandemic.

When Dr Harris was asked where the WHO stands on the debate of the origin of COVID-19, she said doctors in France "went back and looked at people who had been tested for influenza and pneumonia and one of them came back as positive for COVID…it would indeed be very useful to go back at the samples taken of people where the diagnosis was not clear."

When The Agenda's Stephen Cole asked Prof Sikora about the prospect of the US halting its WHO funding, Prof Sikora said, "Children in Africa will die if Mr Trump cancels his subscription - there's no doubt."
