The death toll from the coronavirus outbreak has risen to 170, and a confirmed case in Tibet means it has reached every region in mainland China.
Chinese health authorities said there were 7,711 confirmed cases in the country as of 29 January.
Infections have also spread to at least 15 other countries.
The World Health Organization (WHO) will meet on Thursday to again consider whether the virus constitutes a global health emergency.
“In the last few days the progress of the virus, especially in some countries, especially human-to-human transmission, worries us,” WHO Director-General Tedros Adhanom Ghebreyesus said on Wednesday.

Russia, or the Russian Federation, is a transcontinental country located in Eastern Europe and Northern Asia. It extends from the Baltic Sea in the west to the Pacific Ocean in the east, and from the Arctic Ocean in the north to the Black Sea and the Caspian Sea in the south.
Russia spans more than one-eighth of the Earth’s inhabited land area, stretching eleven time zones, and bordering 16 sovereign nations. Moscow is the country’s capital.
The Soviet Union was dissolved in 1991 and since 1993 Russia been governed as a federal semi-presidential republic.

Tibet is a region in East Asia covering much of the Tibetan Plateau spanning about 2,500,000 km2. It is the traditional homeland of the Tibetan people as well as some other ethnic groups such as Monpa, Tamang, Qiang, Sherpa and Lhoba peoples and is now also inhabited by considerable numbers of Han Chinese and Hui people.
Tibet is the highest region on Earth, with an average elevation of 4,380 m (14,000 ft). Located in the Himalayas, the highest elevation in Tibet is Mount Everest, Earth’s highest mountain, rising 8,848.86 m (29,032 ft) above sea level.
The Tibetan Empire emerged in the 7th century. At its height in the 9th century, the Tibetan Empire extended far beyond the Tibetan Plateau, from Central Asian’s Tarim Basin and the Pamirs in the west to Yunnan and Bengal in the southeast.
The region declared its independence in 1913 and maintained its autonomy until 1951. Today, China governs western and central Tibet as the Tibet Autonomous Region while the eastern areas are now mostly ethnic autonomous prefectures within Sichuan, Qinghai and other neighbouring provinces.
The World Health Organization is a specialized agency of the United Nations responsible for international public health. The WHO Constitution, which establishes the agency’s governing structure and principles, states its main objective as “the attainment by all peoples of the highest possible level of health.”
