Chinese officials announced Sunday that the country was banning indefinitely the trade of wildlife products in markets, supermarkets, restaurants, and on e-commerce platforms. The source of the virus has been traced to a seafood market that was illegally selling wildlife.
Places that breed wildlife were placed under quarantine and the transportation of wildlife was also banned.
Quarantines and evacuations

Additional medical supplies and staff are due to arrive in the city, including 14,000 protective suits, and 110,000 pairs of gloves, goggles, and masks. Videos circulated on Saturday showing throngs of people lined up for examinations. Many complained they had been turned away because the hospitals were at capacity.
"We are steadily pushing forward the disease control and prevention ... But right now we are facing an extremely severe public health crisis," said Hu Yinghai, deputy director-general of the Civil Affairs Department, in a news briefing.
Dozens of cities are also under quarantine, with schools and universities postponing the start a new semester until further notice.
Full threat still unclear
Most of the people who lost their lives to the virus were middle-aged or elderly and had a pre-existing medical condition.
Officials caution that the rapid increase in the death toll and number of infections does not necessarily indicate that the disease is spreading more quickly. It may instead reflect improved monitoring and reporting practices.
