BEIJING (AP) — China is swiftly building a 1,000-bed hospital dedicated to patients infected with a new virus that has killed 26 people, sickened hundreds and prompted unprecedented lockdowns of cities during the country’s most important holiday.

On the eve of the Lunar New Year, transportation was shut down today in at least 10 cities with a total of about 33 million people. The cities are Wuhan, where the illness has been concentrated, and nine of its neighbors in central China’s Hubei province.

“To address the insufficiency of existing medical resources,” Wuhan authorities said in a Friday notice, the city is constructing a hospital modeled after the Xiaotangshan SARS hospital in Beijing. The facility will be a prefabricated structure on a 270,000-square-foot lot, slated for completion Feb. 3.

The SARS hospital was built from scratch in 2003 in just six days to treat an outbreak of a similar respiratory virus that had spread from China to more than a dozen countries and killed about 800 people. The hospital featured individual isolation units that looked like rows of tiny cabins.

Normally bustling streets, malls and other public spaces were eerily quiet in Wuhan on the second day of its lockdown. Masks were mandatory in public, and images from the city showed empty shelves as people stocked up for what could be an extended isolation. Train stations, the airport and subways were closed; police checked incoming vehicles but did not entirely close off roads.

Hospitals in Wuhan were grappling with a flood of patients and a lack of supplies. Videos circulating online showed throngs of frantic people in masks lined up for checks.
