Antonio Guterres was speaking at the opening of the first virtual World Health Assembly, the decision-making body of the World Health Organization (WHO) held over two days with a focus on the coronavirus.

Opening the assembly, Switzerland's President Simonetta Sommaruga said: "In the past, the WHO has been able to learn lessons from epidemics which the organization has had to deal with,
"I am convinced that the organization will also be able to carry out a thorough and critical review of the current crisis to improve its future health emergency management."
