Dr David Nabarro said:
It has been an honour and a privilege to visit so many countries and see some of the truly inspiring work going on to improve people's health.
It has been a tough yet rewarding campaign and whilst disappointed, I urge everyone to unite behind the new Director-General and his vision for the World Health Organization. Only by working together and sharing ideas can we improve the health of people everywhere.
I am optimistic for the future under the leadership of Tedros and wish him all the best in his new role.
