All of them have fought on the front lines against the virus in China.

"All the team members have rich experience in COVID-19 treatment," said team leader Zhou Lin, deputy director of the Chongqing Health Commission. "We have set up four technical groups — in medical treatment, epidemic prevention and control, testing and nursing."

The team is also bringing medical supplies to Algeria that were donated by the Chongqing municipal government. The supplies include protective clothing, face masks and goggles.
