Twenty-three bus lines had been suspended by 10 am on Tuesday. Bus service to provinces including Jiangsu, Hunan and Henan, which have reported outbreaks in recent days, has been suspended, as has service at some subway stops in the city.

Shows and performances at scenic areas in Wuhan were also suspended as of Tuesday and summer classes at training centers canceled.

Supplies of daily necessities, including rice, flour, meat, eggs, vegetables and milk, are abundant and prices are stable, the city's commerce bureau said.

All outlets of the 13 major supermarkets as well as over 400 gas stations are operating as usual, the bureau added.

"We have increased supplies to the stores around the closed residential communities. If there is any store running out of stock we can replenish it within two to three hours," said a staff member at Zhongbai Holdings Group, a retail outlet chain operator, in Wuhan.

Wuhan resident He Zhiqiang said, "Stocks of some goods are running out at online platforms, but supplies are ample at supermarkets."
