I am afraid for Dr. Tedros’ safety. The World Health Organization Director-General and I are walking from the WHO’s midtown-Manhattan offices to the nearby U.N. campus, where Tedros is participating in the U.N. General Assembly. As we cross avenues amid a chorus of honking horns, Tedros is so intent on answering my questions, rarely breaking eye contact, that he appears not to notice traffic lights changing and cyclists whizzing past at alarming proximity.
