The World Health Organization chief Tedros Adhanom Ghebreyesus will self-isolate over the coming days after he had been in contact with someone who tested positive for Covid-19.
WHO said this on late Sunday in a tweet.
"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," reads his tweet.
Tedros has been at the forefront of the United Nations health agency's efforts to battle the pandemic, reports AFP.
"It is critically important that we all comply with health guidance. This is how we will break chains of #COVID19 transmission, suppress the virus, and protect health systems," reads WHO chief's another tweet.
The 55-year-old former Ethiopian minister of health and foreign affairs has for months reiterated that each person has a role to play in halting the spread of the virus.
Geneva, where WHO is headquartered, declared a fresh state of emergency on Sunday and said it would go beyond Swiss national measures and shut down all bars, restaurants and non-essential shops.
The number of confirmed COVID-19 cases has surpassed 46.4 million globally, with 1.19 million fatalities and more than 31 million recoveries, according to the latest tally from Johns Hopkins University.
