China Railway Construction Corp, one of the country's two biggest rail construction contractors by sales revenue, will send the first group of medical teams with experience in fighting COVID-19 to Nigeria on Wednesday to help with the country's battle against the virus.

The 15-member team was selected from the group's affiliated hospitals. They are scheduled to work in Nigeria for 30 days and will provide necessary medical aid and guidance on epidemic prevention and control to the railway's Chinese and Nigerian employees in the West African country.

The Chinese doctors, who specialize in such areas as infectious disease prevention, pulmonary and critical care medicine, also will share their practical medical experiences in Nigeria, which demanded its citizens remain indoors in Lagos, Abuja and Ogun state for 14 days, starting from last Monday.

Nigeria is one of the railway's core country markets in Africa, with more than 140 projects under construction and a total contract value of $16.6 billion. At present, there are 1,600 Chinese workers and 12,763 Nigerian employees building railroads, subways, bridges, and other infrastructure and service facilities in the country.
