Coronavirus Outbreak Outside China is World's 'Greatest Concern', WHO Chief Says VOA News The head of the World Health Organization warned Thursday that the coronavirus outbreak outside China is now the world's "greatest concern." Despite a decline in the number of new cases in China for the second straight day, Tedros Adhanom Ghebreyesus told reporters at his daily briefing in Geneva, "It's what's happening in the rest of the world that's now our greatest concern." The WHO director-general said the global community is "at a decisive point," but "If you acted aggressively now, you can contain the virus. You can prevent people getting sick. You can save lives." Health officials around the globe are focused on what measures they can take to stop the spread of a coronavirus that has infected at least 82,000 people in more than 40 countries since it emerged in China in late December. The United States and South Korea called off joint military drills, and the U.S. issued a new travel warning advising its citizens to avoid going to South Korea, which has reported the most cases outside of China so far. South Korean health officials said Thursday there were 505 more cases, increasing its total to 1,766. .
