BEIJING — Amid the further containment of COVID-19, China is forging ahead with business resumption. The following are the latest facts and figures:

— Shanghai Pudong International Airport has opened two "cabin rooms" to screen air passengers for the novel coronavirus, the Shanghai Customs said on May 21.

With a total area of 360 square meters, the two rooms located at the T1 and T2 terminals have 44 sampling booths that can work around the clock to offer nucleic acid tests for even big passenger flows, according to customs officials.

Their opening is part of the airport's preparation for resumed passenger traffic, the customs said.

Shanghai has demanded nucleic acid tests on all arrivals from overseas since March. Previously the tests at the airport were performed in converted buses, but officials later decided to build sampling facilities inside the terminals to better prepare for extreme summer weather like thunderstorms and typhoons.

— With the last asymptomatic case released from medical observation on May 21, Northeast China's Heilongjiang province has cleared all existing asymptomatic cases, the provincial health commission said on May 22.

Heilongjiang had been cleared of confirmed COVID-19 cases as the last patient was discharged from hospital after recovery on May 16.
