Director general of the World Health Organisation (WHO) , Dr Tedros Adhanom Ghebreyesus, says he has been receiving death threats and racist insults from people.He said some personal attacks came from people in Taiwan a few months ago. Ghebreyesus brushed off these personal attacks on Wednesday in a press conference, but said a line was crossed when people insulted Africa. He would have been alluding to rumours being circulated about vaccines being tested in Africa."Then I don't tolerate [it], then I say people are crossing a line...we cannot tolerate that," he said. "When it's personal, when it's death threats, I didn't care, I didn't respond... I am a very proud black person."I assure you, we [as WHO] will do everything we can to serve humanity. We will do everything to help us have no regrets at all."
