The director of the World Health Organization tweeted Sunday he will go into self-quarantine after coming into contact with someone who tested positive for COVID-19.
Dr. Tedros Adhanom Ghebreyesus said he is well and not showing symptoms but will be working from home as a precaution.
"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," he tweeted.
