World Health Organization (WHO) Director-General Tedros Adhanom Ghebreyesus said late Sunday that he was self-quarantining after someone he had been in contact with tested positive for COVID-19, but stressed he had no symptoms, NDTV reported.

“I have been identified as a contact of someone who has tested positive for #COVID19. I am well and without symptoms but will self-quarantine over the coming days, in line with @WHO protocols, and work from home,” Ghebreyesus said in a tweet.
