In the days before scientists understood how yellow fever was transmitted - and well before there was a vaccine - people referred to the disease by how it manifested itself. They called it “Vómito Negro” - black vomit. In this episode, Dr Sylvain Aldighieri from the Pan American Health Organization helps us chart the deadly history of yellow fever from 3000 years ago through the present day. We also speak to Dr Ibrahima Soce Fall, WHO’s Assistant Director-General for emergency response about the setting up of the EYE strategy and the plan to eliminate yellow fever epidemics by 2026.
