BEIJING, Feb. 9 (Xinhua) -- China has stepped up efforts to curb the spread of the novel coronavirus (2019-nCoV). Here are the latest developments:

-- Authorities on Sunday started to disinfect the city of Wuhan twice a day to beef up efforts in containing the outbreak of the novel strain of coronavirus. Wuhan is the epicenter of the virus outbreak in central China's Hubei Province.

-- More medical teams are arriving in virus-hit Wuhan to help battle the epidemic.

On Saturday night, 260 medical workers came to Wuhan from the Third Xiangya Hospital of Central South University, bringing new medical equipment and supplies. A charter plane of Xiamen Airlines brought 264 medics from Xiamen City, in east China's Fujian Province, and authorities sent 132 medical staff by plane from Wuxi City, in the eastern Jiangsu Province.

Chinese health authorities have dispatched a total of 11,921 medical personnels from across the country to Hubei Province to aid the fight against the novel coronavirus pneumonia, according to the National Health Commission on Sunday.

-- Trade unions in China have provided a financial aid of more than 20 million yuan (about 2.9 million U.S. dollars) to help Hubei Province battle the epidemic.

The All-China Federation of Trade Unions also donated 200 tonnes of disinfectants and 20,000 masks.

-- Chinese authorities have reassured producers of key medical supplies that the government would be the ultimate buyer in a move to encourage production to contain the novel coronavirus outbreak.

Such products initially include test kits, medical goggles, medical protective gear and masks, as well as their raw materials, and the list will be adjusted with the development of the epidemic, according to a guideline jointly issued by several ministries.

-- Authorities have begun closed-off management in some residential buildings in Huanggang, one of the cities worst hit by the epidemic in Hubei.

The buildings include those hosting confirmed cases of infection, suspected cases, patients with fever and possible link to the virus, and those who had close contacts with infected patients.

-- The National Health Commission Sunday said it received reports of 2,656 new confirmed cases of novel coronavirus infection and 89 deaths on Saturday from 31 provincial-level regions and the Xinjiang Production and Construction Corps.

The overall confirmed cases on the Chinese mainland had reached 37,198 by the end of Saturday and 811 people had died of the disease.

The two makeshift hospitals --Leishenshan (Thunder God Mountain) and Huoshenshan (Fire God Mountain), together can accommodate 2,600 beds.

-- China released an application guide to solicit research and development projects on rapid test kits for the novel coronavirus. The on-site quick testing equipment and reagents should be able to identify confirmed infection among suspected patients within 1.5 hours to help prevent and control the epidemic. Research institutes, universities and enterprises can submit applications to the Ministry of Science and Technology from Feb. 8 to 13.
