China donated $6 million on Tuesday to the United Nations' fund for combating the outbreak of the Ebola virus in West Africa.

In addition, the number of Chinese medical workers in affected countries will increase to 1,000 over the next few months.

The donation will be used to support the UN's mission to build up health service networks and collaborative projects with a number of national and local governments. Some of the cash will finance work being carried out by private contractors to improve sanitary conditions in West Africa.
