Ten medical teams from State-owned enterprises were dispatched to Shanghai to aid the city's battle against the current COVID-19 outbreak, said to the State-owned Assets Supervision and Administration Commission on Tuesday.

The State-owned enterprises which sent medical assistance to Shanghai include China National Nuclear Corporation, China National Pharmaceutical Group Corp, and China Aerospace Science and Technology Corporation, according to the commission.

A medical team of 180 nucleic acid testing experts from Xi'an Dianli Hosptial, which is a subsidiary of China General Technology (Group) Holding Co, arrived in Shanghai on April 3 to support a mobile laboratory used to analyze 20,000 nucleic acid test samples every day.

"We will try our best to speed up the testing work. This is what we can contribute to help the city return to normal," said tester Hu Zuomin. "We will not go before the outbreak is under control."

China State Shipbuilding Corporation had sent 12 medical workers from Wuhan, Hubei province to support a makeshift hospital in Shanghai. Meanwhile, 64 medical staff from Shanghai Zhongye Hospital affiliated to China Minmetals Corporation have been working in a makeshift hospital from April 7 to 11.

During two rounds of nucleic acid testing in Shanghai, more than 3,200 medical workers from Zhongye Hospital took samples from over 1.3 million people. In just a month, the clinical department of the hospital completed over 400,000 nucleic acid tests, more than the number of tests it had processed in the past two years combined.
