BEIJING — Over 2,000 tourists who visited China’s Inner Mongolia Region were sent to hotels for two weeks of quarantine after being diagnosed with COVID-19.

This follows reports that COVID-19 has been reported in the region, which is sparsely populated and draws many tourists with its mountains, lakes, and grasslands.

Friday’s announcement by the regional government stated that 2,428 people were under observation in hotels in Ordos and Baotou.

This was after a series of reports about new cases in the region of local infection. Inner Mongolia was responsible for 19 of 48 cases of domestic transmission that were announced Friday.

These quarantines are a sign of the stringent measures China has taken in order to contain the pandemic. They include mass testing, mass screening, lockdowns, and vaccinations.

Millions of people in Lanzhou, Gansu province, bordering Inner Mongolia have been kept at home for the past week due to the discovery of cases. On Friday, ten new cases were reported.

China has reported 4,636 deaths from 91,665 COVID-19 cases since late 2019, when the first cases were discovered in Wuhan, central China.
