Top infections disease official Anthony Fauci said Sunday that after strict containment and mitigation, China's novel coronavirus outbreak is "coming down right now."

On ABC's "This Week," the director of the National Institute of Allergy and Infectious Diseases said it takes several weeks to a few months for the outbreak to dwindle, pointing to China and South Korea as examples.

China, where COVID-19 first set off alarms, passed through the worst, Fauci said. According to a Johns Hopkins University database, the country has had the bulk of the cases and fatalities: nearly 81,000 confirmed cases and more than 3,200 deaths.
